Problems solved by technology

[0005] The low resolution of myocardial SPECT images, small imaging size, continuous myocardial image defects caused by myocardial ischemia, and images of the free end of the bottom of the heart often lead to the failure of traditional methods for calculating the center of foreground objects
Due to the low resolution, small

Abstract

The invention discloses a left ventricle center and a region of interest extraction method, a device adopting the method and a system. According to the left ventricle center and region of the interestextraction method, the device adopting the method and the system, the central position of the left ventricle and the stereoscopic region of interest of myocardium are automatically calculated according to an SPECT cross-sectional image, the central position of the left ventricle and the stereoscopic region of interest of the myocardium are enabled to be distinguished from surrounding tissues andartifacts, a judgment result is enabled not to depend on human experience, the result is accurate, the speed is fast, the calculation speed of myocardial SPECT quantitative indexes is increased, manpower is saved, and efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of SPECT imaging, in particular to a method, device and system for extracting a left ventricular center and a region of interest. Background technique [0002] Emission tomography is a non-invasive nuclear medicine imaging method. Single Photon Emission Computed Tomography (SPECT, Single Photon Emission Computed Tomography) is a type of emission tomography, which has been widely used in pre-clinical drug research and clinical disease diagnosis. . [0003] At present, SPECT / PET is widely used in myocardial tomographic imaging for non-destructive diagnosis of coronary heart disease. However, the traditional qualitative analysis method relies on the naked eye to interpret the image, because it is necessary to analyze dozens of images in the three directions of myocardial short axis X, horizontal long axis Z, and vertical long axis Y, and to compare motion and delay one by one. In this case, the worklo...
