A computer program for reconstruction of images from a scanning gamma camera.
A program was written to convert the output of a scanning gamma camera into a whole body computer image which can then be used to study regional and whole body radiopharmaceutical localization. The electronically masked output of the camera is collected as a dynamic study on the computer with the time per frame set according to scan speed. The program overlays these frames onto a matrix in memory to form the image. The overlayed frame is incremented 1 pixel/frame in the direction of camera motion during camera scanning. The timing of camera motion is automatically determined by the program. Although written for a specific scanning gamma camera, the ideas inherent in the algorithm will allow the reconstruction of whole body images from other scanning cameras.
