Abstract: A PET scanner includes a ring of detector modules encircling an imaging region. Each of the detector modules includes one or more sensor avalanche photodiodes (APDs) that are biased in a breakdown region in a Geiger mode. The sensor APDs output pulses in response to light from a scintillator corresponding to incident photons. A reference APD also biased in a breakdown region in a Geiger mode is optically shielded from light and outputs a voltage that is measured by an analog to digital converter. Based on the measurement, a bias control feedback loop directs a variable voltage generator to adjust a bias voltage applied to the APDs such that a difference between a voltage of a breakdown pulse and a preselected logic voltage level is minimized.

Abstract: Radiation images with different resolutions may be captured using a general-purpose driver configured with a shift register group in a single system. Each shift register is connected to a first gate line or a second gate line via a connection terminal in accordance with wiring of a radiation detector. Under the control of an FPGA, in a case of low resolution imaging, a panel control section outputs OE signals that disable the output of on signals from the shift registers to the first gate lines in accordance with CPK signals. In a case of high resolution imaging, the panel control section outputs OE signals that disable the output of on signals from the shift registers to the second gate lines. In both cases, an on signal outputted from a shift register is inputted to a succeeding shift register.
