Design of a preamplifier card for the photomultiplier tubes of a gamma camera
The service provided by Gamma Cameras (GC) in Nuclear Medicine departments fails because of their breakdown, generally due to the associated electronics and not to the physical detection components. Therefore, it was decided to develop an electronic system that allows the recovery and optimization o...
