False Collisions
5.5.1
Locating the Cause of a False Collision
Under normal operation, the CardioMD system detects a collision by performing a logical OR
operation on the input signals from the individual collision sensors. These sensors include:
•
Collimator surface sensor, detector I
•
Collimator surface sensor, detector II
•
Detector edge sensor, detector I
•
Detector edge sensor, detector II
•
Detector end cover sensor, detector I
•
Detector end cover sensor, detector II
•
Detector top cover sensor
•
Rotate gear cover sensor.
To locate a cause of a false collision, it is practical to disable the sensors one by one in order to
determine whether one of the sensors is causing the problems.
Note
. The collision circuit will report a collision when it detects:
•
An open circuit
•
A short-circuit.
All sensors must have a resistance of approximately 20 k
Ω
in the non-collision state.
