Tumor ablation curative effect prediction method, device, equipment and computer medium

Abstract

The invention discloses a tumor ablation curative effect prediction method, device and equipment and a computer medium. The tumor ablation curative effect prediction device includes a first acquisition module for acquiring an ultrasound image containing a tumor, a first processing module for processing the ultrasound image to obtain a tumor lesion parenchymal image, an expansion module used perform area expanding on the parenchymal image of the tumor lesion in the ultrasound image to obtain an expanded image of the tumor lesion, a second processing module for extracting and screening radiomicsfeatures of the parenchymal image of the tumor lesion to obtain target radiomics features, a second acquisition module for acquiring tumor-related parametric features except ultrasound images and a prediction module for performing tumor ablation curative effect prediction based on the tumor lesion expanded image, the target radiomics feature and parameter features to obtain prediction results oftumor ablation curative effect. Preoperative tumor ablation curative effect prediction can be performed based on ultrasound images and supplemented by parametric features, and limitations are small.

Description

technical field [0001] The present application relates to the technical field of ultrasonic image processing, and more specifically, to a method, device, equipment, and computer medium for predicting the curative effect of tumor ablation. Background technique [0002] Taking breast tumors as an example, with the popularization of mammography and B-ultrasound screening and the improvement of women's awareness of breast diseases, the detection rate of breast tumors is getting higher and higher, and it is showing a younger trend. At present, the ablation of breast tumors is generally guided by B-ultrasound and other medical images, and the ablation needle emits radio frequency, microwave, laser, etc. to heat the tumor focus, so as to achieve the purpose of "killing" tumor cells. Compared with the traditional surgical resection, ablation surgery has the advantages of less trauma, faster recovery, better appearance, less physical requirements for patients, and strong repeatabilit...

Problems solved by technology

[0004] However, in the current evaluation methods for the efficacy of ablation surgery, although the doctor's evaluation can achieve the purpose of preoperative evaluation, it requires a high degree of doctor's experience and is easily affected by the doctor's subjective factors. If the evaluation is wrong, the best treatment will be missed The risk of timing; although regular postoperative follow-up can monitor tumor growth through a period of follow-up examination after ablation, and then intuitively and accurately evaluate the efficacy of ablation surgery, it can only be used for postoperative evaluation of ablation efficacy, which has high limitations
