Problems solved by technology

These factors will lead to irregular deformations such as barrel shape, butterfly shape, rotation, compression, and expansion of the photon event position histogram information. If no processing is done, the online processing cannot determine the row and column coordinates of the crystal pixels during the data acquisition process. It will cause the image resolution to drop, and more seriously, it will cause image information error

Abstract

The invention relates to a crystal position spectrum data segmentation system and method for plant PET. The crystal position spectrum data segmentation system structurally comprises a detector module,a data sending module, a preprocessing module, a corrosion algorithm module and a tabu search module. The method comprises the following steps: obtaining data information from a PET detector, packaging data in the detector into a data packet and sending the data packet, receiving and preprocessing the data packet information, obtaining the number of position spectrum subsets in the preprocessed data information, and segmenting the processed position spectrum data. A tabu search technology is utilized to record and sort the performed optimization process, and the search direction of the next step is guided, so that the strong optimization capability is displayed in the combined optimization neighborhood, and the high solving quality and efficiency are achieved.

Description

technical field [0001] The invention relates to the field of data segmentation, in particular to a plant PET-oriented crystal position spectrum data segmentation system and method. Background technique [0002] Positron Emission Tomography (PET) technology is a three-dimensional imaging non-destructive testing technology that injects positron isotope-labeled compounds into organisms to measure their spatial distribution and time characteristics in vitro. and the latest developments in nuclear medicine imaging for medical research and clinical diagnostics.
