Abstract

The invention provides a processing method and system for a single photon emission computed tomography. The method comprises the steps that wave signals are sampled in a digitized mode; a preset energy window upper limit, a preset energy window lower limit and a preset base line offset are input; according to the base line offset and the digitized wave signals, a digital base line is removed; threshold signals are extracted from the digitized wave signals; the threshold signals are added, and energy digital integration is achieved; according to the energy window upper limit and the energy window lower limit, the integral treated threshold signals are integrated, and a whole threshold event is obtained. The method has the advantages that the speed is high, the processing capacity is strong, the upgrade is easy, and the method is suitable for electronics equipment of digitalized human body single photon emission computed tomography equipment.

Description

technical field [0001] The invention relates to the technical field of single photon emission tomography, in particular to a processing method and system for single photon emission tomography. Background technique [0002] The purpose of single photon emission tomography imaging equipment is to detect and reconstruct the distribution map of tracers in human organs. This distribution map can reflect human tissue structure and corresponding physiological activities. This distribution map can also reflect the metabolic status of human tissues and organs over time. Single-photon emission tomography systems are used in clinical diagnosis and identification of tumors, and are also widely used in the diagnosis of thyroid and cardiovascular activity. [0003] The single photon emission tomography system includes subsystems such as detector array, electronic system, mechanical system, reconstruction algorithm and human-machine interface. A detector array usually consists of a seri...
