Problems solved by technology

[0003] The current medical image processing methods for multi-time series images are not suitable for multi-temporal images, and cannot calculate the changes in image characteristics between different time phases, and many image regions of interest have different imaging performances in different time-phase images. Changes in imaging appearance, reflecting differences between tissues
Therefore, the processing method that can be applied to multi-temporal images is bound to be beneficial to obtain richer useful information from images, but there is a lack of reliable methods

Abstract

The invention discloses a multi-time-sequence image processing method, electronic equipment and a storage medium. The method comprises the following steps: 1) segmenting a multi-time-sequence region of interest; 2) extracting comprehensive features of the region of interest; 3) extracting multi-time sequence image features; 4) processing an image set; and 5) performing feature screening on the feature matrix M obtained in the step 4) and then performing classification through a classifier to obtain an image processing result. According to the multi-time-sequence image processing method, multi-time-sequence image classification of multiple patients can be achieved at the same time, and richer iconography quantitative characteristics can be obtained from multi-time-phase characteristics; Themulti-temporal image features and the feature differences between different temporal images are constructed to jointly form the feature set, so that the iconography performance of different tissues can be reflected more effectively, and richer iconography information can be obtained.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a multi-sequence image processing method, electronic equipment and a storage medium. Background technique [0002] Tumor is a common malignant tumor, such as pulmonary nodules. Clinical studies have found that CT has a high accuracy in diagnosing pulmonary nodules. CT images can be used clinically for disease screening, prognosis evaluation, and efficacy evaluation. Medical image processing and analysis of images can provide favorable data support for doctors' judgments, which has extremely high practical significance. For example, patent 201810165489.6 provides a method for screening lung nodules with low radiation dose using radiomics technology. [0003] The current medical image processing methods for multi-time series images are not suitable for multi-temporal images, and cannot calculate the changes in image characteristics between different time phases, a...
