Abstract

The invention discloses a medical image retrieval method based on feature extraction and similarity matching. In the process of a radiotherapy plan, image registration is a very important key step. The purpose of the image registration in the radiotherapy plan is to find out a template image the most appropriate for a target image and to obtain a best registration result by matching operation for clinical target delineation, organ dose simulation or treatment. Therefore, it is quite important how to search out the most appropriate template image. In the method, 10 morphological features related to the form is combined with medical history information, the features are endowed with different discrimination weights, and finally 10 groups of the most similar images and related information are selected and provided for the doctor to choose, and the most appropriate template image is selected by comprehensive consideration. The operation of the method can guarantee the similarity between the template image and a target image so that it is possible to improve the applicability and the accuracy of the image registration operation in the radiotherapy plan.

Description

technical field [0001] The invention relates to a registration sample extraction method for delineating a target area of ​​a radiotherapy plan, in particular to a medical image retrieval method based on feature extraction and similarity matching. Background technique [0002] With the continuous development of computer science and information technology, medical imaging technology has also developed rapidly, and various new imaging equipment are emerging, such as computed tomography (CT), digital subtraction angiography (DSA), single photon emission tomography, etc. imaging (SPECT), magnetic resonance imaging (MRI), positron emission tomography (PET), etc. Various imaging techniques and inspection methods have their advantages and disadvantages. Not one imaging technique can be applied to the inspection and disease diagnosis of all organs of the human body. It is not that one imaging technique can replace another, but complement each other. , complement each other. In orde...
