摘要： A radiation detector module (10) for use in a time-of-flight positron emission tomography (TOF-PET) scanner (8) generates a trigger signal indicative of a detected radiation event. A timing circuit (22) including a first time-to-digital converter (TDC) (30) and a second TDC (31) is configured to output a corrected timestamp for the detected radiation event based on a first timestamp determined by the first TDC (30) and a second timestamp determined by the second TDC (31). The first TDC is synchronized to a first reference clock signal (40, 53) and the second TDC is synchronized to a second reference clock signal (42, 54), the first and second reference clock signals being asynchronous.

摘要： When detecting scintillation events in a nuclear imaging system, time- stamping and energy-gating processing is incorporated into autonomous detection modules (ADM) (14) to reduce downstream processing. Each ADM (14) is removably coupled to a detector fixture (13), and comprises a scintillation crystal array (66) and associated light detect or (s) (64), such as a silicon photomultiplier or the like. The light detector(s) (64) is coupled to a processing module (62) in or on the ADM (14), which performs the energy gating and time-stamping.

摘要： When detecting photons in a computed tomography (CT) detector, a sensor (10, 38) includes a photodiode that is switchable between liner and Geiger operation modes to increase sensing range. When signal to noise ratio (SNR) is high, a large bias voltage is applied to the photodiode (12) to charge it beyond its breakdown voltage, which makes it sensitive to single photons and causes it to operate in Geiger mode. When a photon is received at the photodiode (12), a readout transistor (18) senses the voltage drop across the photodiode (12) to detect the photon. Alternatively, when SNR is low, a low bias voltage is applied to the photodiode (12) to cause it to operate in linear mode.

摘要： A PET scanner (8) includes a ring of detector modules (10) encircling an imaging region (12). Each of the detector modules includes at least one detector pixel (24,34). Each detector pixel includes a scintillator (20, 30) optically coupled to one or more sensor APDs (54) that are biased in a breakdown region in a Geiger mode. The sensor APDs output a pulse in response to the light from the scintillator corresponding to a single incident radiation photon. A reference APD (26, 36) also biased in a breakdown region in a Geiger mode is optically shielded from light and outputs a temperature dependent signal. At least one temperature compensation circuit (40) adjusts a bias voltage applied to the sensor APDs based on the temperature dependent signal.
