Question

Assume that two FDG point sources with activity 100 kBq and 110 kBq, respectively, are placed in front of a PET camera and determine: (a) Object contrast (b) Signal-Difference-to-Noise Ratio in the image for 10 s collection time. The camera has a diameter of 80 cm with 5 cm wide detectors that have 30% intrinsic efficiency. The sources are placed near the center of the camera's Field of View.​
