Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] In the existing technology, to realize the data transmission of the PET system, each acquisition module needs to be connected to the data summary module. After the data summary is carried out by the data summary module, it is handed over to the coincidence processing module for conformity judgment, and finally transmitted to the host computer to complete the image. reconstruction. At the same time, another bus for transmitting instructions is required to be connected to each acquisition module respectively, so as to complete the relevant configuration of the acquisition module and read the state of the acquisition module. However, if you want to obtain images with higher resolution, you need to...

Abstract

The invention discloses a system and method for realizing data transmission in a PET system, which is used to simplify the structure of the PET data transmission system. The system includes n acquisition modules: nth-level acquisition module, i-level acquisition module and first-level acquisition module, each acquisition module is serially connected; n is an integer greater than 1, and i is each integer greater than 1 and less than n; the nth level acquisition module is used to send the data collected by itself to the n‑1th level Acquisition module; the i-th level acquisition module, used to superimpose the data received from the i+1-th level acquisition module and the data collected by itself, and send the superimposed data to the i-1th level acquisition module; The first-level acquisition module is used to superimpose the data received from the second-level acquisition module and the data collected by itself, and send the superimposed data to the host computer, so that the host computer can receive data from the first-level acquisition module. data for a match determination.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a system and method for realizing data transmission in a PET system. Background technique [0002] PET (Positron Emission Tomograph, Positron Emission Computed Tomography) system is an advanced molecular imaging device. Some tracers containing positron nuclides will release positron e+ during the decay process, and the released positron e+ will annihilate with negative electron e- in the surrounding environment after moving for a certain distance in the human body, resulting in A pair of gamma photons with equal energy (511KeV) and opposite propagation directions (about 180 degrees). Using the detection equipment of the PET system, the gamma photon pairs can be detected, and then the existence of positrons can be analyzed to obtain the concentration distribution of the tracer in the subject's body. [0003] The detection equipment of the PET system generally incl...
