A germanium (Ge) camera with laminar collimator–detector geometry, ROLEC, simulating a 195×195 mm 2 detection area, has been constructed and tested. The detector consists of five separate Ge blocks grooved into distinct electrical channels. Results show that ROLEC measuring times have to be about 3× greater than Anger camera measuring times to achieve a 5% signal‐to‐noise ratio with each device. Both spatial and energy resolution of the ROLEC exceed that of the Anger camera but sensitivity variations along the detector strips pose a significant problem in development of a clinically useful device.
