The C-Arms derive their name from the rigid, C-shaped weldment that supports the Image Intensifier,
collimator, CCD Camera, and X-ray tube. These components together are commonly called the “C”, and
the entire assembly from the casters up is known as the “C-Arm”.
The X-Ray tube generates an X-ray beam that is shaped and oriented by the collimator. After passing
through patient anatomy, the beam is directed onto a film cassette to produce a radiographic film
image, or through the image intensifier and CCD camera, to convert the X-ray image to a video signal
that is transmitted to the Workstation for display, processing, and storage.

transformer will be powered by R1 and R2. After about 1.5 second, the R1 and R2 are shorted by the
relay, which is controlled by timer circuit. The R1 and R2 can resolve the power on surge current problem.
Relay JR1 in PDU board energizes, then the relay JR1 and timer circuit in PDU board begin to work.
Pressing the Power Off key on control panel will power off the equipment.
In interlock loop, the interconnect cable, display board, collimator control board (MP1), MCB, filament
control board (MP4), and PDU Board compose the safety loop. If the interconnect cable between C-Arm
and the Workstation is removed or any PCBs in C-Arm loose from slot due to collision, the relay JR2 will
not be energized so that the system can't be powered on. There is a relay in workstation, which is
powered by PC +12V. The contactor of the relay is connected to power off key, if the PC isn't powered off,
the power off key on C-Arm is open and the system will not be powered off. This function is used to
protect PC from unintended power off.

4.5. Filament Control Board
Filament control board (MP4) can be separated to two parts simply, one is power unit and other is control
unit. The power unit offers the energy to the filament transformer primary coil and the control unit
control the energy input to the transformer by control the output voltage of the power unit. The theory is
illustrated in the following chart. For detailed circuit schematics of filament control board, please refer to
Appendix.
In the power unit, the DC 24V is fed through two parallel power transistors V6 & V7 and drives the pushpull complementary amplifier consisting of V8, V9, V10 and V11. The V6, V7, V13 and V12 are used to
adjust the voltage of the filament transformer primary. A 600Hz pulse as the V8, V9, V10 and V11 drive
signal is from MCB. V1, V4, R4 and R12 compose over current protecting circuit. When the current
through R4//R12 is too big, a signal will lock then trigger the alarm module.
In the control unit, A3A acts as an analog adder and drivers the V13 and V12 through A3B. Adjusting
POT1 may control the filament base heating current.
In Fluoroscopy mode, gate A4B is on, and MAC is fed to A3A. MAC is the Fluoro mA reference signal and
controls the tube current in Fluoro mode.
In the system, the Radiography current is constant 20mA. If the Radiography mode been selected, IDRGHC is active, gate A4B is off, gate D5C is on, a 10V voltage inputs to A3A positive port for Radiography
preheating.
When the exposure commend signal “EXPRCM-HC” is effective, gate A4D & D5D are on. A 10V voltage
adds to A3B for Radiography quick heating and KVC signal adds to the negative port of A3B through
amplifier A2B for KV compensation.
The relay K1 is used to select the small focal spot of the X-ray tube in Fluoro and the large focal spot in
Radiography In the Radiography mode, IDRG is high, K1 is active, and the large focal spot works.

transformed their voltage levels between +3.3V and +15V through optical couple circuit.
4.6. Monoblock
Monoblock can generate X-ray. It mainly consists of high voltage generator and tube insert. All high
voltage components are put into oil box, which can enhance the insulation performance.
Monoblock generates 110kV inside the oil tank. The input voltage changes from 0V to 240V peak value.
High voltage is got from high frequency and high voltage transformer T1. The primary coil is 10T and the
secondary coil is 2500T. So the maximum voltage of secondary side is 60kV peak value at 40kHz.

High voltage circuit comprises rectifier circuit and voltage doubler. High voltage circuit composes of high
voltage diode D1-D4, high voltage capacitor C1-C4. If output voltage from T1 is 60kV peak value the high
voltage circuit output 120kV to the tube.
The controller needs to get kV value and mA value from monoblock. KV sense circuit comprises high
voltage resistor R1, R4 and sense resistor R2, R3. The high voltage resistor value is 400M ohm, sense
resistor is 20k ohm If the voltage on the tube is 120kV the +kV output 3V and –kV output –3V. mA value is
measured by serial resistor between –mA and ground. So the mA voltage value is negative.

Subsystem
The tube is used to generate X-ray. This tube is a kind of double focus with fixed copper anode tube. It is
suitable for oil insulation generator.
Analog signals KV_GND and MA_CAT of sealing board are the anode and cathode of mA current signal
respectively.
There are two temperature measurement circuits in sealing board. One’s output is analog signal
OIL_TEMP.
The other’s output is connected/open status between THERMAL_SWITCH_A and THERMAL_SWITCH_B. If
the temperature of oil tank is higher than a preset threshold, the relationship between

Collimator collimates the X-ray beam to the appropriate field size and user’s setting. The x-ray beam
passes through Grid to reduce scattered X-ray photons. Image Intensifier converts this X-ray into lights
for each field size selection, and sends the light to CCD Camera head. CCD Camera head captures the
light image and sends the analog video to CCU. The CCU performs preliminary image processing, and
outputs analog signal to Frame Grabber Card. Frame Grabber card in the workstation reads the analog
signal, register into digital video, and the CPU performs real-time post-processing (Brightness, Contrast,
Edge Enhance, Zoom, and Negate) to be sent to image display. CCU also analyzes the analog input
signal, and outputs an indicator kv+ to MCB; higher kv+ when the X-ray dose is higher than desired, and
lower kv+ when the X-ray dose is lower than desired. With AutoTechnique enabled, MCB S/W converts
this signal into digital signal, and send command to X-ray Generator to increase or decrease kVp/mA
depending on the kv+ value.
4.8.2. Collimator Control
The collimator is an electromechanical assembly designed to allow the operator to restrict the size and
shape of the X-ray beam. The unit has a lead iris and shutters and is mounted directly over the X-ray
tube beam aperture. The collimator use three independent motors to control the following degrees of
freedom:
•
The diameter of the iris aperture
•
The gap spacing between the semi-transparent copper leaves
•
The rotational position/orientation of the copper leaves
Collimator specification:
•
Length×Width×Height: 290 mm×120 mm×100 mm
•
Weight: 2kg
4-16
Subsystem
•
8 leafs Motorized iris collimator
•
Shutter rotate angle: 180 degree
The collimator is controlled by control panel through MCB and collimator control board (MP1).
The function of the collimator control board is to control the iris and the Semi-transparent leaves of
collimator. The circuit of MP1 is in Appendix. Motor M1 opens or closes the shutter. Depressing the switch
“OPEN” or “CLOSE” on the console panel energizes the motor drives the petals for desired width.
Analog signals (SWPO, SRPO, FSPO and VREF), which are transmitted from MP1 to MCB, show the location
information of iris. They are amplified by operational amplifier circuit, and then sampled by ADC circuit of
MCU. The output control signal of MCB is transmitted to MP1 through optical couple circuit. LEFT, RIGHT,
OPEN, CLOSE, IRD and IRI are control command from control panel. F1 and F2 are three-horizon control
of image intensifier. IDRG-HC is exposure control command.

4.9. Computer and Peripheral
4.9.1. Computer
The computer mounted in the workstation takes over most of the communication with external devices
and is the main device of workstation. The computer runs Linux system working with image grabber card
and display card.
The computer has 2 1GB memory banks and a 250GB hard disk with standard 3.5’ SATA interface. The
partitioned SATA hard drive contains Linux system and system software. The Serial ATA interface
provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:
•
Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set
any jumpers or other configuration options.
•
Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
•
Scalability to higher performance levels.
The Ethernet port can be used to connect DICOM printer. The system operator can use the Ethernet
connector to interface the workstation to a DICOM server through the facility’s computer network. Once
the Workstation is connected to the network, the operator can query the local server to determine if the
desired images are available for download, and then download selected images to the Workstation. The
Workstation can also upload images over the same network connection. Detailed instructions on DICOM
operation are available in the Operator Manual.

NOTE
The following section describes the instruction how to set Dose Group and X-ray Control
according to the following Table “Exposure Management Matrix”. If the instruction
contradicts the corresponding regulatory requirements of certain countries or regions (for
example, some regulatory requirements are updated), change the setting according to the
regulatory requirements.
Select Dose Group option by country to set the dose limitation in normal (standard) and HLF
exposure. The available options are:
Normal 88 and HLF 100
Normal 50 and HLF 50
Normal 50 and HLF 100
Refer to the following table “Exposure Management Matrix” to set Dose Group.
The skin dose rate in the Dose Group represents the value for conditions of free-in-air irradiation at the
patient skin: 30cm along the beam axis from the image intensifier surface.
6-7
Brivo OEC 850 Mobile C-Arm X-ray Product Service Manual
1. Two dose groups in nomral (standard) fluoro mode
-Normal50: The skin dose rate does not exceed 50mGy/min in standard fluoro mode, such as
Australia, Japan, New Zealand, etc.
-Normal88: The skin dose rate does not exceed 88mGy/min in standard fluoro mode, such as
USA, Germany, etc.
2. Two dose groups in HLF mode:
-HLF50: The skin dose rate does not exceed 50 mGy/min in HLF mode, such as Australia, New
Zealand, etc.
-HLF100: The skin dose rate does not exceed 100 mGy/min in HLF mode, such as Japan, Italy, UK,
etc.
For the country, such as USA, if the skin dose rate shall not exceed 176 mGy/min in HLF mode from its
regulatory requirements, the system will use HLF100 in HLF mode because the maximum skin dose rate
of the X-ray tube cannot exceed 100 mGy/min.
3. For some country, its dose limitation should be the combination of the above normal and HLF groups.
For example,
-Australia: Normal50 and HLF50
-China: Normal88 and HLF100
4. For countries or regions that have a higher standard fluoro dose (at the patient skin) rate limit than
USA, the dose limits are set to the same value as for USA.
5. For countries or regions that have a higher HLF dose (at the patient skin) rate limit than USA, the dose
limits are set to the same value as for USA.
6. For countries or regions that do not specify standard fluoro dose at patient skin, the dose limits are set
to the same value as for USA.
7. For countries or regions that do not specify HLF dose at patient skin, the dose limits are set to the
same value as for USA.

Electrical Shock
WARNING
9-2
This system can generate lethal voltages. Practice safe electrical testing
procedures when performing periodic maintenance procedures.
Periodic Maintenance
After taking X-rays, the high voltage cables can retain a lethal charge, even if you
power down the system. Even though the contacts are recessed, high voltages can
arc several inches from their terminals if the cables are removed from the
connector wells. Use caution when disconnecting high voltage cables even when
the power is turned off. If you remove these connections, immediately discharge
their contacts against the high voltage tank case (ground).
WARNING
X-radiation Exposure
The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray
shielding in place. Use lead shielding and draping to protect personnel.
Lead aprons, radiation monitors, and appropriate radiation shields must be utilized
for the protection of all personnel in the vicinity while performing tests. Living
human anatomy should never be used as a phantom or demonstration aid. Do not
produce radiation in hallways.
WARNING
Many of the PCB's in this system contain components, which are sensitive to ElectroStatic Discharge (ESD). Observe ESD safety procedures.
