Test of the Acquisition System in an Analog Gamma Camera
The quality control of an analog gamma camera in our nuclear department concerns exclusively the detection head. To evaluate the acquisition system we use a test system composed of an output card and software called ASST. The test consists of transforming the digital data of a scintigraphic image into three analog signals similar to those delivered by the detection head. These signals are introduced into the acquisition system for reconstructing the image. The software ASST allows comparison between the original and the acquired image in order to evaluate the quality of acquisition.
