Embodiment Construction

[0055] In the following description, numerous details are provided in order to provide a thorough understanding of the invention. However, it will be appreciated by those skilled in the art that the following description relates only to preferred embodiments of the invention and that the invention may be practiced without one or more of these details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0056] In order to solve the above problems, the present invention proposes a photon detection method, device, equipment and system as well as a storage medium. According to an embodiment of the present invention, the sensor array is divided into different areas, and some shared readout circuits are shared between different areas to reduce the number of channels (each readout circuit can be regarded as a readout channel, reducing the number of channels means reduce the number of readout circuits cons...

Abstract

The invention provides a photon detecting method, device and facility and a storage medium. The photon detecting method comprises the steps that a first number of energy signals respectively output bya first number of shared reading circuits connected with a sensor matrix and a second number of energy signals respectively output by a second number of shared reading circuits are received, whereinthe sensor matrix is averagely divided into two sensor areas, the first number is equal to the number of sensors in each sensor area, the first number of shared reading circuits are correspondingly connected with all the sensors in each sensor area on a one-to-one mode, and each individual reading circuit is connected with the corresponding individual sensor in the sensor matrix; the responding projection positions of high-energy photons are determined based on energy distribution regularities of the first number of energy signals and the second number of energy signals. The shared reading circuits and the individual reading circuits arranged based on propagation characteristics and distribution characteristics of flickering photons in the method read electric signals output by the sensorsso as to achieve channel decrease.

Description

technical field [0001] The present invention relates to the field of positron emission imaging, in particular to a photon detection method, device, equipment and system, and a storage medium. Background technique [0002] In recent years, the positron emission imaging system has gradually shifted from the photomultiplier tube (Photomultiplier Tube, PMT for short) era to the silicon photomultiplier tube (Silicon Photomultiplier, SiPM for short) era. The full name of positron emission imaging is Positron Emission Computed Tomography (PET). and the main means of clinical diagnosis. [0003] SiPM has small size and high detection efficiency, which makes the detector compact and the system has high sensitivity. But precisely because of the small size of SiPM, the number of SiPMs coupled with scintillation crystals of the same cross-sectional area is far greater than the number of PMTs. Taking a single-ring whole-body PET system with an aperture of 76cm as an example, the light...
