Problems solved by technology

There are several problems with this design: 1. The front-end circuit is too close to the PMT, and once a fault occurs, it is easy to burn out the PMT
2. The signal processing circuit in the front-end circuit is generally prone to heat. Because it is too close to the PMT, the PMT is more sensitive to temperature. In order to strictly control the temperature of the PM

Abstract

The invention relates to a novel PET detector framework based on a SiPM. The novel PET detector framework comprises a detector box, an electronics box and a connecting cable, the connecting cable comprises an upper cable and a lower cable, the upper cable is arranged between the detector box and the electronics box and used for transmitting voltage needed for work of the detector box and output analog signals, the lower cable is arranged on the electronics box and used for transmitting digital and analog signals generated by the electronics box to a data acquisition system, a thermal insulation material is further arranged between the detector box and the electronics box, and the upper cable penetrates through the thermal insulation material. According to the novel PET detector framework, the performance and stability of a PET detector are improved, and the bulk temperature control difficulty and maintenance cost of the PET detector are also effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a SiPM-based PET detector architecture. Background technique [0002] Positron Emission Tomography (PET) is a nuclear medicine imaging technique that provides three-dimensional and functional images of the whole body. [0003] Traditional PET systems are based on PMT (Photomultiplier Tube, photomultiplier tube), PMT output signal is small (less than 5 millivolts), high operating voltage (1000-1500 volts), susceptible to external environmental interference (electromagnetic field, temperature, etc.). In order to ensure the signal quality, the design of the PMT-based PET detector requires that the front-end circuit (mainly including the power voltage divider module and signal processing circuit) be as close to the PMT as possible. There are several problems in this design: 1. The front-end circuit is too close to the PMT, and once a fault occurs, the PMT is easy to burn o...
