Description

technical field [0001] The invention relates to the technical field of radiation detection and imaging, in particular to a high-speed and low-time-space complexity PET crystal position spectrum data segmentation system and method. Background technique [0002] Positron Emission Tomography (PET) to obtain super-sensitive functional images has great advantages in advanced imaging diagnosis of tumors, cardiovascular diseases, brain function and other diseases. Currently commonly used PET detectors mainly adopt the design method of a crystal array composed of crystal strips coupled with a photoelectric conversion device. When the gamma photon is incident on the scintillation crystal, the gamma photon interacts with the crystal to deposit energy and generate a visible light signal. The photomultiplier tube receives the generated light signal and converts it into a corresponding electrical signal output. According to the obtained electrical signal, it can The incident position of...
