END-TO-END
STEREOTACTIC QA
Perform image transfer
QA, dosimetry and
machine QA within the
exact coordinate system
of commercially available
stereotactic head frames
and frameless mask systems
•PHYSICS TOOLS AT YOUR FINGERTIPS
The Lucy 3D QA Phantom minimizes clinically relevant
errors by quantifying system variances in the imaging
chain to within 0.1mm. Increase your confidence in your
system to correctly image known volumes, distances and
geometries. Confirm that CT/MRI/Angioscans and image
fusion are accurately recreated within the TPS, assuring
precise target dose delivery
•SRS PATIENT DOSIMETRY QA
Obtain absolute, relative and point dose dosimetry QA
measurements at isocenter and at exact positions off
