Problems solved by technology

[0004] The technical problem to be solved by the present invention is to intelligently locate the bones of the front and rear two whole-body imaging images collected by professional equipment. When the bone scan image is positioned for the bone, it takes a long time, the proportion of experience dependence is high, and the bone is easy to be wrongly positioned.

Abstract

The invention discloses a whole-body bone imaging bone segmentation method based on atlas registration. The method comprises the following steps: acquiring original whole-body bone imaging data collected by professional equipment; subjecting the original whole-body bone imaging data to preprocessing including pollution detection processing, pollution repair processing, standardization processing,registration processing and regularization processing; and according to a deformation segmentation template stored in the system, carrying out segmentation processing on the preprocessed whole-body bone development image to obtain a segmentation result of whole-body bone development. By means of the method, bone positioning can be conducted on an image obtained through single whole-body bone scanning examination, a basis is provided for bone lesion positioning, development quality is improved by automatically reducing a difference through bone development pollution detection and a pollution repair algorithm, and the development difference between different whole-body bone scans is solved; and rapid, accurate and intelligent positioning of the whole-body bone imaging skeleton is achieved.

Description

technical field [0001] The invention relates to an image processing method, in particular to a whole-body bone imaging bone segmentation method based on atlas registration. Background technique [0002] For the localization of whole-body bone imaging, three kinds of examinations are commonly used: MRI examination, CT examination, and SPECT whole-body bone imaging examination. Due to its good sensitivity and comprehensiveness, SPECT is currently the main examination method in the field of bone metastasis diagnosis in my country. This article only talks about the most commonly used SPECT whole-body bone imaging examination, that is, the image data of each examination is manually positioned by professional nuclear medicine technicians. At present, in some hospitals with better medical conditions, for patients who may suffer from cancer, the usual method is to use professional equipment to collect two whole-body imaging images, front and back. After completing the data collect...
