A uterine myoma three-dimensional model reconstruction method and system

Abstract

The invention provides a hysteromyoma three-dimensional model reconstruction method, which comprises the following steps of: defining a region: segmenting a region with a specific voxel value range according to a voxel value of a nuclear magnetic image, and recording the region as a myoma region; wherein points of the myoma area are selected, and the interference area outside the myoma area is removed through area growth; A myoma region correction step: utilizing erasure filling or range limitation to correct the myoma region; An image conversion step: extracting a nuclear magnetic image of the myoma region, recording the nuclear magnetic image as an extracted nuclear magnetic image, and binarizing the extracted nuclear magnetic image to obtain a converted image; and a three-dimensional reproduction step: carrying out surface reconstruction on the converted image to obtain a myoma three-dimensional model of grid data composed of triangular surfaces. A three-dimensional model of hysteromyoma is quickly reconstructed, and the problems of auxiliary positioning and monitoring are solved by combining high-strength ultrasonic treatment equipment; A three-dimensional model of a uterine myoma focus is constructed through a nuclear magnetic image of a patient, and the size, the shape and the direction of myoma can be clearly displayed.

Description

technical field [0001] The present invention relates to the field of medical imaging, in particular, to a method and system for reconstructing a three-dimensional model of uterine fibroids, in particular to a method for rapidly reconstructing a three-dimensional model of uterine fibroids based on a nuclear magnetic image region segmentation growth algorithm. Background technique [0002] Uterine fibroids, also known as uterine leiomyomas, are relatively common benign tumors of the female reproductive system. Most of them are asymptomatic. With the aggravation of symptoms, the abdomen gradually becomes lumpy or oppressive. This disease occurs in women aged 35 to 50. The etiology It is not yet known that the incidence of the disease has increased in recent years and has gradually become younger. Because the symptoms of the disease are hidden, early diagnosis and treatment are one of the main means to reduce the incidence of the disease. At present, medically recognized diagno...

Problems solved by technology

However, the above-mentioned patent documents need to perform denoising preprocessing on the two-dimensional nuclear magnetic image, and some important information may be lost during the denoising process, resulting in incomplete image information, and it is necessary to find all non-empty voxels, and the calculation efficiency is not high. 3D model reconstruction is based on 3D polygonal patches, which is not accurate enough in terms of construction accuracy
