Image processing system and method

Abstract

The invention provides an image processing method, which comprises the steps of acquiring a first image of a target tissue, and acquiring a second image of the target tissue after the first image is acquired; segmenting and extracting tissue structures of the first image and the second image; registering the first image and the second image based on the tissue structures, and establishing a registration mapping relation between the first image and the second image; displaying a first sub-image of the first image; and displaying a second sub-image, which corresponds to the first sub-image, of the second image based on the registration mapping relation. The invention further provides an image processing system. According to the image processing system and method provided by the invention, a direct corresponding relation of two groups of images is established by adopting an interactive registration mode, and a display interface for comparative analysis is provided so as to carry out comparative evaluation between the two groups of images, so that a real-time evaluation effect can be acquired and is visually displayed, and the cost of comparative evaluation is low.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing system and method. Background technique [0002] Ultrasound-interventional tumor therapy has recently attracted more and more attention from doctors because it can relieve the constraints of surgical resection such as poor liver function, blood coagulation mechanism, and poor heart and kidney function in patients with liver cancer. Before ultrasound-guided tumor interventional ablation, it is necessary to obtain and evaluate images through contrast-enhanced ultrasound. By checking and analyzing whether the interventional treatment area completely covers the tumor area and the safety margin, it is possible to evaluate whether the current treatment is successful. And according to the image, the incomplete ablation area can be treated with supplementary acupuncture on the spot. [0003] In the process of obtaining images by contrast-enhanced ultrasound, i...

Problems solved by technology

Since the above evaluation is carried out on two-dimensional images, on the one hand, this scheme cannot show whether the tumor is completely ablated in three-dimensional space; good correspondence

However, the evaluation scheme based on CT / MRI images collects 3D CT / MRI before operation, and collects CT / MRI again one month after operation. Although the quality of CT / MRI images is better than that of images, this method does not meet the requirements of immediate evaluation. , and the cost is higher
