Ultrasonic contrast quantitative analysis method and system for dynamic follow-up tumor local radiotherapy and chemotherapy effects and computer readable storage medium

Abstract

The invention provides an ultrasonic contrast quantitative analysis method and system for dynamic follow-up tumor local radiotherapy and chemotherapy effects and a computer readable medium, and relates to the technical field of medical imaging. The ultrasonic contrast quantitative analysis method comprises the following steps: firstly, collecting continuous dynamic contrast images from the beginning of ultrasonic contrast agent injection, preprocessing the dynamic contrast images, then carrying out focus labeling based on breathing dynamic compensation, and finally carrying out fitting calculation to obtain a time-intensity curve TIC. Errors caused by factors such as equipment and human factors are eliminated through preprocessing, interference of respiratory movement of a patient on an image is counteracted on the basis of focus labeling of respiratory dynamic compensation, and finally a TIC curve is obtained through fitting calculation, so that the accuracy and repeatability of quantitative analysis are effectively improved; and a basis is provided for non-invasive sensitive tumor local radiotherapy and chemotherapy effect evaluation.

Description

technical field [0001] The present invention relates to the technical field of medical imaging, in particular to a method, system and computer-readable storage medium for quantitative analysis of contrast-enhanced ultrasound for dynamic follow-up of the effects of local radiotherapy and chemotherapy for tumors. Background technique [0002] Radiation therapy (hereinafter referred to as "radiotherapy") and chemotherapy (hereinafter referred to as "chemotherapy") are the main treatment methods for patients with advanced solid tumors, which can increase the local control rate of the tumor. During the treatment period, timely evaluation of the treatment effect and adjustment of the treatment plan are helpful. Helps prolong patient survival and improve quality of life. However, radiotherapy and chemotherapy are adjuvant or local palliative treatments, and its efficacy is difficult to accurately evaluate. At present, the most commonly used imaging method to evaluate the curative ...
