Abstract

Provided are a segmentation method and device based on an image of radionuclide imaging, including: determining a potential target region from an image of radionuclide imaging using a standardized value of pixels in the image of radionuclide imaging and an average standardized value and a standard deviation of pixels in a non-target region, and according to the boundary pixels and pixels within a boundary of the potential target region, and the average standardized value of the pixels of the non-target region, finally determining the boundary of a target of interest. The method or device needs to receive a non-target region selected by a user only when calculating an average standardized value and a standard deviation of pixels in the non-target region, thus significantly reducing manual intervention of a link, so as to avoid the subjectivity of segmentation results and improve the certainty of the segmentation results.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a segmentation method and device based on radionuclide imaging images. Background technique [0002] Radionuclide imaging images include Positron Emission Tomography (PET) images, referred to as PET images, and Single Photon Emission Computed Tomography (SPECT) images, referred to as SPECT images, radionuclide Imaging images have a wide range of applications in the medical field. When using PET or SPECT images for medical quantitative or semi-quantitative diagnosis, it is usually necessary to segment them, that is, to separate the region of interest in the image from the background. [0003] PET or SPECT images have the characteristics of low contrast and low spatial resolution. Therefore, the existing automatic image segmentation methods cannot accurately segment the region of interest. The existing segmentation of PET or SPECT images generally consists of Experienced doctors u...
