摘要:
Proximity controls for controlling the proximity of a gamma camera to a patient during a scan of the patient. The proximity controls consist of two spaced apart energy screens, each comprising 200 beams, parallel to and spaced from the detector of the gamma camera. When neither screen is interrupted, the camera is moved towards the patient. When both screens are interrupted, the camera is moved away from the patient. When only the screen farthest from the detector is interrupted, the camera is braked so as not to move away from or towards the patient.
