摘要： A detector (22) detects an event. First and second time-to-digital converters(TDCs) (70, 72) generate first and second time stamps (TS1, TS2) for the detection of the event. The first TDC and the second TDC are both synchronized with a common clock signal (62) that defines a fixed time offset between the second TDC and the first TDC. An autocalibration circuit (120) adjusts the first TDC and the second TDC to keep the time difference between the second time stamp and the first time stamp equal to the fixed time offset between the second TDC and the first TDC. The detector may be a detector array, and trigger circuitry (28) propagates a trigger signal from a triggering detector of the array of detectors to the first and second TDC's. Skew correction circuitry (132, 134, 136, 142, 60, 162) adjusts a timestamp (TS) based on which detector is the triggering detector.
摘要翻译：检测器（22）检测事件。第一和第二时间数字转换器（TDC）（70,72）生成用于检测事件的第一和第二时间戳（TS1，TS2）。第一TDC和第二TDC都与定义第二TDC和第一TDC之间的固定时间偏移的公共时钟信号（62）同步。自动校准电路（120）调整第一TDC和第二TDC以保持第二时间戳和第一时间戳之间的时间差等于第二TDC与第一TDC之间的固定时间偏移。检测器可以是检测器阵列，并且触发电路（28）将触发信号从检测器阵列的触发检测器传播到第一和第二TDC。偏斜校正电路（132,134,136,142,60,162）基于哪个检测器是触发检测器来调整时间戳（TS）。

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： 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.
