Abstract: A silicon photomultiplier includes a plurality of microcells providing a pulse output in response to an incident radiation, each microcell including circuitry configured to enable and disable the pulse output. Each microcell includes a cell disable switch. The control logic circuit controls the cell disable switch and a self-test circuit. A microcell' s pulse output is disabled when the cell disable switch is in a first state. A method for self-test calibration of microcells includes providing a test enable signal to the microcells, integrating dark current for a predetermined time period, comparing the integrated dark current to a predetermined threshold level, and providing a signal if above the predetermined threshold level.

Abstract: Various approaches are discussed for using four-side buttable CMOS tiles to fabricate detector panels, including large-area detector panels. Fabrication may utilize pads and interconnect structures formed on the top or bottom of the CMOS tiles. Electrical connection and readout may utilize readout and digitization circuitry provided on the CMOS tiles themselves such that readout of groups or sub-arrays of pixels occurs at the tile level, while tiles are then readout at the detector level such that readout operations are tiered or multi-level.

Abstract: The present approach relates to the use of detector elements (i.e., reference detector pixels) positioned under septa of an anti-scatter collimator. Signals detected by the reference detector pixels may be used to correct for charging-sharing events with adjacent pixels and/or to characterize or correct for focal spot misalignment either in real time or as a calibration step.
