SOMATOM Definition Edge
The Reference in Single Source CT
For decades, Siemens has been the undisputed innovation leader in highend CT imaging. However, the clinical need to continuously improve image
quality persists. Therefore, Siemens designed the SOMATOM Definition
Edge with the revolutionary Stellar Detector – the first fully integrated
detector that significantly reduces electronic noise. This takes CT imaging
where it has never gone before.
The uniqueness of the Stellar Detector allows the SOMATOM Definition
Edge to generate ultra-thin slices, thus further improving spatial resolution
in CT. It can visualize even finest image details and thus significantly
enhances, for example, calcified plaque and stent analysis. It lets you see
what was previously unseen.
The combination of the reduced noise level of the Stellar Detector and
SAFIRE*, Siemens’ raw-data-based interactive reconstruction, is the
perfect match for ultra-low dose imaging. Together, they eliminate
the contradiction between outstanding image quality and low dose.
Physicians get more diagnostic quality at less patient radiation.
Finally, Dual Energy becomes truly suitable for single source CT imaging.
With the novel capabilities of the Stellar Detector and the only doseoptimized single source DE scan mode, the SOMATOM Definition Edge
makes it possible to add tissue characteristics to morphology. With this,
formerly unspecific morphology can now be specified for a higher level
of diagnostic information. With these unrivaled features, the SOMATOM
Definition Edge enters new frontiers in medical imaging and becomes
The Reference in Single Source CT.

*In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical
location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate
dose to obtain diagnostic image quality for the particular clinical task.

The SOMATOM Definition Edge is the reference in single source CT with out­
standing image quality at high temporal resolution and high acquisition speed.
Unprecedented spatial resolution
The SOMATOM Definition Edge is equipped
with the Stellar Detector and the STRATON®
tube with z-Sharp™ Technology. This
combination is the key to increasing spatial
resolution. Using a flying focal spot with
two distinct X-ray beams, z-Sharp acquires
two individual, overlapping slices. The Stellar
Detector delivers slices with a thickness
of 0.5 mm, resulting in a routine spatial
resolution of up to 0.30 mm, which is
equivalent to approximately 18.2 lp/cm.
8
Uncompromised temporal resolution
The new SOMATOM Definition Edge gantry
has a rotation speed of 0.28 s. Combining
this speed with the Stellar Detector and the
STRATON tube, the scanner is able to achieve
an outstanding temporal resolution of
142 ms. This makes it for ideal imaging with
significantly reduced artifacts. At the same
time, it can utilize the spatial resolution of
up to 0.30 mm within the entire FoV of up
to 500 mm. This is performance dedicated
to outstanding clinical imaging.
The STRATON tube and the
newly designed gantry enable
high spatial resolution even at
an acquisition speed of up to
230 mm/s. This takes motion
out of the equation.
The Stellar Detector puts the
SOMATOM Definition Edge in a
class of its own with a routine
spatial resolution of up to
0.30 mm, allowing visualizations
of very fine structures or lesions.
Unparalleled acquisition speed
High acquisition speed with high spatial
resolution is essential in acute care scenarios
because providing diagnosis within the
‘golden hour’ mandates the precise
localization and identification of critical
injuries. The challenge for CT is to reduce
motion artifacts when unconscious or
uncooperative patients have to be scanned
quickly. SOMATOM Definition Edge rises
to the challenge with an acquisition speed
of up to 230 mm/s at a spatial resolution
of 0.30 mm.
High-pitch high-resolution CT
Increasing spatial resolution beyond the
actual width of a detector row requires
overlapping slices. For conventional CT
systems, this means reducing pitch to
facilitate the slice overlap. For scans
requiring high pitch, the missing overlap
then reduces spatial resolution. With
z-Sharp, however, the overlap is achieved
by acquiring two distinct projections.
Consequently, the two slices overlap
independently of the used pitch and can
always provide highest resolution.

The SOMATOM Definition Edge is the reference in low signal imaging
with optimized dose efficiency – essential for bariatric examinations
or iterative reconstruction.
Optimized low-signal imaging
There are various reasons for scanning
with low signals. For example, bariatric
patients can cause strong attenuation.
Reducing dose can also cause low signals.
Many recent innovations, especially
iterative reconstruction solutions, reflect
this. It is therefore a logical step to
introduce a detector that is specially
optimized for low-signal imaging: the
Stellar Detector with TrueSignal Technology.
10
Optimized bariatric imaging
In a growing number of countries, a large
portion of the population is considered
obese. The SOMATOM Definition Edge
answers the challenge of bariatric imaging
with a 78 cm gantry bore and a table load
capacity of more than 307 kg. And, of
course, there is the outstanding image
quality delivered by the new Stellar Detector
with TrueSignal Technology.

Optimized imaging at the right dose
Iterative reconstruction allows significant

data at lower dose and then maintain the
image quality during the reconstruction.
SAFIRE (Sinogram Affirmed Iterative
Reconstruction) uses this approach to
enable a dose reduction of up to 60%*.
The unique low signal capabilities of the
Stellar Detector optimize image quality,
resulting in even higher sharpness and
clarity despite the reduced dose.

Comprehensive dose protection
In the mid-1990s, Siemens introduced its
CARE philosophy following the ALARA
(As Low As Reasonably Achievable)
principle. The idea has been to utilize every
means available to reduce patient exposure.
Siemens is the only vendor to offer a dose
protection portfolio that optimizes the
scan according to all relevant parameters.
From patient size to examination type, from
mA to kV, and from scan preparation to
data evaluation – everything is taken into
consideration.

is designed to contribute to

process resulting in an absolute

Optimized patient-centric imaging
With CARE Dose4D™, Siemens offers a
unique solution that actively modulates the
tube current to the patient’s anatomy in real
time. Additionally, CARE kV automatically
suggests the appropriate kV (the selected
voltage) to optimize the contrast-to-noise
ratio of the image while limiting the
applied dose. CARE kV takes both the
patient’s body type and the examination
type (non-contrast, bone, soft tissue,
vascular) into consideration.
*In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist
and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. The following test method was used to determine
a 4 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogeneity, low-contrast resolution and high contrast resolution were assessed in a
Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file.

Enhanced low kV image quality makes the SOMATOM Definition Edge the
reference in functional imaging for Single Source Dual Energy examinations.
Routine-ready Single Source Dual Energy
Siemens’ pioneering application development has allowed CT to expand into
new clinical fields. The introduction of
Dual Energy (DE) imaging has added
tissue characterization to morphology.
Thanks to a combination of routine-ready
scan modes and enhanced low-kV image
quality at low dose, the SOMATOM
Definition Edge brings these new
applications to everyday clinical practice.
12
Calculi characterization*
in clinical routine
Many people in developed countries suffer
from urinary stone disease. The imaging
modality of choice for urinary stone disease
is a low-dose, non-contrast CT scan. It is
very easy to perform, does not require
intravenous contrast and covers the entire
abdomen and pelvis. The essential benefit
in the diagnosis with Dual Energy CT is
that the stone type can be identified.
Functional imaging, e.g. with dual
energy (image 1–3) or perfusion
(image 4) , makes it possible to add
tissue information to morphology
Tissue characterization – Gout
Gout is amongst the most common
inflammatory joint diseases and many
people in the western world are afflicted
by this painful, destructive disease.
With syngo.CT DE Gout*, a non-invasive
assessment of gout is feasible. The
algorithm color codes different attenuation
values, so that the uric acid produced by
the disease is directly verified, confirming
the definite diagnosis of gout.
Routine-ready metal artifact reduction
Metal artifacts pose severe difficulties in
CT imaging due to the resulting artifacts.
Single Source Dual Energy now offers a
solution. The unique Stellar Detector in the
SOMATOM Definition Edge is specifically
optimized to handle low kV signals with
HiDynamics. And syngo.CT DE Monoener­
getic Imaging* enables the minimization
of metal artifacts by specifically selecting
keV levels at which the metal objects have
least impact on image quality.
Routine-ready dynamic imaging
Stroke is one of the three most frequent
causes of death worldwide. In the diagnosis
and treatment of stroke cases, time is of
the essence. With the Adaptive 4D Spiral,
Siemens has introduced a scan mode that
performs perfusion evaluations beyond the
limitations of a static detector. In addition,
the SOMATOM Definition Edge, with
the Stellar Detector and HiDynamics, is
the perfect choice for the acquisition of
dynamic datasets, typically done at low
kV levels.
Perfusion information is crucial
in many clinical fields such as
stroke or tumor assessments.
The Adaptive 4D Spiral is key to
making these exams ready for
clinical practice.

it is ready for review – allowing,
for instance, a quick assessment
of an aortic dissection.
Fast decisions in acute care
CT is the modality of choice when it comes
to diagnostic imaging in acute care
situations – whether it is for a triple rule-out
of acute chest pain, stroke assessment,
poly-trauma, or acute abdominal pain.
The CT Acute Care Engine provides clinical
functionality that delivers decisive results
for all of these challenging indications.
Thanks to automatic pre-processing,
the case is ready for reading as soon as
it is opened.

Core Technologies
Edge Technology
The SOMATOM Definition Edge delivers thinner slices for
increased spatial resolution with the unique Stellar Detector.
Thinner slices
Thinner slices deliver more image detail,
but also less light quants per voxel, i.e.
higher image noise. This lowers the signalto-noise ratio. In addition, electronic noise
causes cross-talk, which leads to slice
blurring. Conventional CT compensates
this by increasing dose. Thus, the further
reduction of slice thickness was limited.
Until now.
32
The Stellar Detector
The Stellar Detector introduces the next
generation in detector technology,
succeeding gas and solid-state technology.
Using nano-technology, it is possible to
miniaturize the electronic components
on the detector elements. For the first time,
it is therefore possible to fully integrate
the detector directly into the photodiode.
This full electronic integration is Siemens'
revolutionary TrueSignal Technology.
Innovation delivers outstanding results
High spatial resolution and high signal-tonoise ratio (SNR) are reliable indicators of
excellent image quality. Together they
describe the image detail level and sharpness that can be made visible while acquiring
diagnostic CT images. In addition, the Stellar
Detector provides a homogeneous slice
profile with the same spatial resolution
and SNR in the entire Field of View (FoV),
which is essential for consistently high
image quality.
focal spot
Conventional Technology
Cross-talk resulting
from slice blurring in a
conventional detector.
Edge Technology minimizes noise
Full electronic integration of the detector
elements minimizes electronic noise and
cross-talk. Without cross-talk, slice blurring
between neighboring detector rows can
be significantly reduced, thus making the
individual slice profile much more precise.
Siemens’ Edge Technology creates an
almost perfect model of the focal spot and
detector, generating a slice thickness of
0.5 mm. With the minimized electronic noise,
0.5 mm constitutes not only a high-res mode
but a standard mode.
detector
projection
Edge Technology
Minimized cross-talk from
the Stellar Detector creates
an almost perfect model of
the focal spot. The result is a
slice thickness of 0.5 mm.
Higher signal-to-noise ratio
Normally, the reduced light quants of a
0.5 mm slice would need compensation.
The TrueSignal Technology of the Stellar
Detector has a new answer to this
challenge: instead of increasing dose,
it makes more efficient use of the initially
available quants per voxel. As the electronic
noise of the detector is minimized, the
overall noise is reduced, so that the quants
contribute to a higher SNR.

TrueSignal Technology
TrueSignal Technology optimizes dose efficiency and delivers
outstanding image quality at reduced signal level.
TrueSignal Technology raises SNR
Based on the full electronic integration of
the Stellar Detector, TrueSignal Technology
significantly reduces electronic noise.
The resulting SNR is improved for better
utilization of low signals. Low-signal
datasets benefit from increased sharpness
and clarity, as the detector can now
differentiate much better between the signal
of individual voxels and the surrounding
image data.
34
Comparable noise level at lower signal
At high signal levels, the noise produced
by the Stellar Detector with TrueSignal
Technology is more or less the same as
the one produced by conventional CT
technology. However, when the signal is
lowered – either by high attenuations from
obese or broad shouldered patients, or
by reducing the applied mA – the impact
of TrueSignal Technology increases.
Effective use of low signals
Conventional detectors have a comparatively
high intrinsic noise level that impairs image
quality. The electronic integration of the
Stellar Detector and TrueSignal Technology
lowers the noise level significantly, so that
the available signal can be processed more
efficiently. This means that when there is
high attenuation from very large patients,
the detector can make better use of the
measured low signal.

Iterative reconstruction
When using iterative reconstruction
methods, the CT images are retransferred
to raw data after the initial reconstruction.
Comparing this new synthetic raw data
with the acquired data makes it possible to
identify differences. An updated image is
then reconstructed with reduced image
noise but without noticeable loss of
sharpness. This is repeated several times,
reducing image noise incrementally and
correcting geometrical imperfections.

Iterative reconstruction allows to reduce mA,
thus lowering the signal at the detector.
Consequently, SAFIRE examinations benefit
from the low-signal advantages of the
Stellar Detector and TrueSignal Technol­
ogy. Combined with the high computational
power of Siemens’ FAST image reconstruction
system (IRS), they enable the use of SAFIRE
in crucial clinical routine scenarios such as
acute care. The result is more benefits for
a larger number of patients.

enhanced image quality in low kV scans and functional CT examinations.

Full dynamic range for more sensitivity
Thanks to full electronic integration, the
Stellar Detector now benefits from an
extended dynamic range instead of having
to switch bandwidth like conventional
detectors. This unique feature is called
HiDynamics. It increases the sensitivity of
the detector for visualizing finer structures,
especially for low kV datasets.
Comparison of the 80 kV Dual
Energy data set (left) with the
140 kV Dual Energy data set
(right) shows: almost identical
image detail level in 80 kV due
to the improvement resulting
from HiDynamics.
Adding functional information
HiDynamics and TrueSignal Technology
thus have clear benefits in functional
imaging applications such as Dual Energy.
After acquiring two consecutive scans at
different kV levels, the two datasets can be
referenced and can then add functional
information, such as tissue characteristics,
to the morphology. Especially for low KV
datasets HiDynamics significantly increases
the detail level and sharpness of images.
Dose-optimized Single Source DE
When multiple scans of the same region
have to be performed, dose protection
becomes ever more important. Siemens has
introduced a Single Source Dual Energy
scan mode that utilizes all dose reduction
functionalities without limitations: e.g.,
CARE Dose4D for real-time mA modulation,
or SAFIRE for the reduction of mA through
iterative reconstruction.
Scanning at half the dose
The Single Source DE scan mode consists
of two successive spiral scans at different
energy levels. In order to avoid doubling
the dose, both scans are performed at
approximately half dose. As the scan uses
regular spirals, all dose reduction features can
be utilized without limitations. The excellent
capabilities of the Stellar Detector regarding
low dose / low signal imaging make possible
the industry’s only Single Source Dual
Energy scan mode optimized for low dose.
