PET/CT distributive software system and medical equipment

Abstract

The invention relates to the technical field of medicine, and particularly discloses a PET / CT distributive software system and medical equipment. The software system comprises five subsystems, i.e. a control console subsystem, an image processor subsystem, a CT collection rebuilding subsystem, a PET collection rebuilding subsystem and a main controller subsystem, both the control console subsystem and the image processor subsystem respectively adopt a four-layer architecture, the CT collection rebuilding subsystem, the PET collection rebuilding subsystem and the main controller subsystem adopt a three-layer architecture, the five subsystems are connected through a network topological structure, and the instruction communication and data transmission are realized by virtue of network communication. The system is clear in division, only two computers are respectively used for the collection rebuilding of PET and CT, so that the transmission time of original data can be shortened; moreover, the requirement on the performance of a control console also can be lowered; meanwhile, the development progress of software can be accelerated, the reliability of the software is improved, and stability in network communication can be realized.

Description

technical field [0001] The invention relates to the field of medical technology, and specifically discloses a PET / CT distributed software system and medical equipment. Background technique [0002] The full name of PET is "Positron Emitter Tomography". Like ordinary nuclear medicine, it uses the comprehensive principle to display the medical imaging technology of living biological activities. The collected data is reconstructed by back projection and iterative methods. The distribution of emitters in space, and Displayed in a tomographic manner, a PET image is generated, but it cannot accurately locate the lesion, and it is difficult to effectively guide clinical treatment; CT is a computer tomography scan, which uses X-rays to irradiate the selected tomographic level of the human body. The amount of X-rays transmitted is an imaging principle for obtaining tomographic images. It can clearly display the tomographic images of the human body, and accurately locate the size, loc...

Problems solved by technology

This physical structure of data acquisition and image reconstruction improves the independence and speed of acquisition and reconstruction, but increases the consumption of original data transmission time between the acquisition computer and the reconstruction computer, and also increases the complexity of the system structure
