Method and device for accurately constructing breast visualization model based on CT image omics and evaluation method

Abstract

The invention discloses a method, a device and an evaluation method for accurately constructing a breast visualization model based on CT imageomics, and the modeling method comprises a method and is characterized by comprising the following steps: (1) carrying out the three-dimensional reconstruction of breast volume measurement based on CT data; and (2) performing three-dimensional reconstruction of the breast based on the data measured in the step (1). According to the method, the construction of the breast prosthesis three-dimensional construction model is perfected. According to the method, large-batch and large-scale three-dimensional reconstruction work can be effectively, accurately and rapidly carried out, and then the breast size which is more in line with the human body proportion can be constructed according to data of the whole human body scanned by CT and a visual digital simulation system and a virtual operation, so that the leap of the individualized operation quality of breast reconstruction is promoted, and the operation efficiency is improved. And meanwhile, beneficial help is provided for scheme design and simulation of various plastic surgery operations.

Description

technical field [0001] The present invention relates to breast imaging, in particular to a method and device for constructing a breast model based on CT radiomics. Background technique [0002] Breast cancer is one of the most common malignant tumors threatening the health of Chinese women. According to the 2019 WHO survey, breast cancer is the cancer with the highest incidence among urban women all over the world. About 1.5 million new cases, Asian women are about 10 years earlier than Western women, the incidence of breast cancer in my country has also increased significantly in the past 5 years, and breast cancer (≤35 years old), due to the improvement of comprehensive diagnosis and treatment and mortality The patient's social, family status, emotional status, and breast sensation retention have attracted much attention. Accompanied by the transformation of the treatment model of breast cancer from the "biomedical model to the biological-psychological-social medical model"...

AI Technical Summary

Problems solved by technology

[0005] However, the method in the above-mentioned patent is a cone-beam breast CT (CBBCT-3D) modeling measurement method for breast density detection, which is not applicable in the field of breast reconstruction

For the field of breast reconstruction, the difficulties are: 1. How to ensure the symmetry of both breasts; this is a very difficult problem in manual measurement. The volume of breast tissue changes after isolation, and manual measurement may easily lead to post-exit measurement. The deviation of the value, and the difficulty of preoperative measurement lies in the irregular shape of the breast and the change of volume with tension

2. Due to the pulling effect of gravity on the skin and the degree of skin retraction after tumor reduction, it is impossible to evaluate the expected position of the mammary gland after gland excision and prosthesis implantation replacement through digital technology, which increases the difficulty of breast reconstruction , It is necessary to constantly change the body position during the operation to observe the effect of the operation, which increases the time consumption of the operation, is not conducive to the nursing during the operation, and brings hidden dangers to the safety of anesthesia

At the same time, since it is impossible to formulate individualized breast reconstruction according to the morphological characteristics of the thorax and the patient's reminder features, the effect of no blood is mainly based on the experience of the chief surgeon, and the surgical results are uneven.
