A transaxial view of a typical ZiPET system. Here the high-resolution detector is added into a microPET II system which has 30 low-resolution detector blocks uniformly spread over a ring of diameter 160 mm. The diameter of field of view is suppose to be the size of 30 mm. The high-resolution detector is positioned 15 mm away from the center at an angle θ with respect to the x-axis.
