[Basic research for development of pinhole camera using a Geiger Mueller counter].
To visualize the scattered X-ray distribution in the diagnosis domain, we examined whether a Geiger Mueller (GM) counter could be applied to a pinhole camera as an X-ray detector. The GM counter detects radiation at certain detection points. To obtain two-dimensional images using the GM counter, the detector needs to be moved two-dimensionally. We constructed an apparatus using industrial actuators to move the detector. To investigate the usability of the developed apparatus, the scattered X-rays from the phantom were measured using the GM counter. The images obtained were then compared with those measured using the phosphor plate. Our results demonstrated that the GM counter can detect low count-rate radiation, but further research will be needed to obtain clear two-dimensional images. In this paper, we propose that the GM counter can be used as a complementary detector to a phosphor plate.
