PET coincidence data volume control method, device and equipment and storage medium

Abstract

The invention relates to a PET coincidence data volume control method and device, computer equipment and a storage medium. The method comprises the following steps: receiving delay coincidence data of a PET detector in a set time period, wherein the set time period comprises at least one moment; obtaining a delay count value corresponding to the delay coincidence data at the first moment according to the delay coincidence data, wherein the delay count value is used for representing the number of delay coincidence data in a first moment and a previous moment in the set time period; according to the delay count value and a preset delay count threshold value, carrying out packet loss processing on delay coincidence data at a first moment and a subsequent moment in the set time period, wherein the delay counting threshold value is related to the throughput of the data acquisition link for transmitting and receiving the instant coincidence data and the delay coincidence data. By adopting the method, the implementation cost of follow-up devices, workstations and the like in accordance with the circuit can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, device and storage medium for controlling the amount of PET compliance data. Background technique [0002] With the continuous development of PET (Positron Emission Computed Tomography, Positron Emission Computed Tomography) technology, when patients go to the hospital to check some specific problems, doctors usually inject radionuclides into the patient's body and use the PET system to detect The nuclides in the patient's body are detected to obtain PET images, and then the patient's examination results can be obtained by analyzing the PET images. [0003] Currently, PET systems mainly include ring detectors, coincidence circuits, and workstations. Among them, the ring detector mainly detects the photons released by nuclides in the patient's body, converts the photons into electrical signals, and converts the electrical signals into digital sig...

Problems solved by technology

[0004]However, as the number of detectors in the PET system continues to increase, and more and more signals are transmitted from the detectors to the coincidence circuit, the coincidence data screened by the coincidence circuit The amount of data will also increase, which has very high requirements for the hardware and software of subsequent devices and workstations that conform to the circuit, which will make the implementation costs of subsequent devices and workstations that conform to the circuit higher.
