2.3.3.8 Source to receiver communication pairing
Description:
A software algorithm that detects communication failure between electronic devices in the
radiation safety chain.
Purpose:
Due to the distributed computing nature of the scanner EDAQ architecture, radiation
safety tasks are controlled by separate EDAQ boards. If one or more of the EDAQ boards
are not communicating with the others, tasks may not be completed or safety status
information might not be passed to other devices.
If the communication chain between devices in upper and lower heads and cable end
electronics is disrupted, shutters will fail closed, heads will be sent offsheet and a safety
alarm will need to be cleared before scanning can resume.
2.3.3.9 Sensor position mapping
Description:
A coded resistance value at each sensor power port on the head that is read by each
sensor EDAQ board at power up to determine its location in upper and lower heads.
Purpose:
The mapping of sensor locations allows for a software check to ensure that appropriate
sources and receivers are properly position matched as a pair.
2.3.3.10 Source locks and tamper proof screws
Description:
Locks on radiation sources that secure source assemblies to head platforms.
Tamper proof screws on the radiation source platform secure the sensor modules to head
assembly.
Purpose:
These screws and locks restrict the removal of radiation sources to authorized persons
only.
