摘要： A system and tuning method to collaboratively calibrate high voltage DAC values and Photomultiplier Tube DAC values of photomultiplier tubes of a gamma camera so that the detector produces a valid energy spectrum over the entire detector surface. A method for tuning a gamma camera having a plurality of photosensors, exposes the photosensors to scintillation photons corresponding to nuclear radiation of known energy; measures an energy output corresponding to each specific photosensor; calculates an average enemy output of all photosensors in the camera; collaboratively adjusts a DAC value corresponding to a voltage applied to a specific photosensor and a DACHV value corresponding to a high voltage applied to the camera based on the calculated average energy, energy output of each photosensor, and a target energy value corresponding to said known energy; and repeats the calibration until convergence is achieved between the average energy, energy output, and target energy.

摘要： Using standard or “off the shelf” cable to interconnect between the PET block detector and the detector circuit may save substantial costs given the number of PMTs in a PET system. Given space constraints, simple maintenance with reduced risk of disturbing cabling is desired, making ongoing use of standard cabling without adding further cabling desired. To implement digital gain control, a further communication is provided between the PET detector block and the detector circuit. Since the standard cable may not have additional wires for such communications and to reduce timing degradation, the PMT signals are combined, such as generating position and energy signals at the PET detector block. The four PMT signals are reduced to three signals without reduction in function, allowing a fourth twisted pair of wires in a CAT5 cable to be used for digital gain control.
摘要翻译：使用标准或现货电缆在PET块检测器和检测器电路之间进行互连可以节省大量成本，因为PET系统中PMT的数量。鉴于空间限制，需要简单的维护，减少干扰布线的风险，不断增加布线需求，不断使用标准布线。为了实现数字增益控制，在PET检测器块和检测器电路之间提供进一步的通信。由于标准电缆可能没有用于这种通信的附加电线并且减少定时劣化，所以组合PMT信号，例如在PET检测器块处产生位置和能量信号。四个PMT信号减少到三个信号，而不会降低功能，允许CAT5电缆中的第四根双绞线用于数字增益控制。
