Efficient and accurate division method for ultrasonic positioning tumor image

Abstract

The invention discloses an efficient and accurate division method for an ultrasonic positioning tumor image, and relates to the technical field of medical image.The method comprises the following steps that S1, the ultrasonic positioning tumor image of a patient is shot, the shot image is recorded and stored into a storage device of a computer, medical image pictures of the same tumor focus under three dimensions are collected, and the medical image pictures are stored in a database; forming a data set, and preprocessing the ultrasonic positioning image; s2, ROI region extraction is carried out on the data set, gray level image conversion is carried out on the preprocessed image, PET / CT data set images added with pseudo colors are converted into gray level images, ROI region image extraction is carried out, local features, namely an ROI region image corresponding to a focus region, are extracted from global gray level images of the data set according to clinical marks, and the ROI region image is normalized. According to the method, the textural features in the sub-regions are extracted in a computer-aided manner, and the dividing rules of the sub-regions are combined, so that the boundary of the tumor is better reflected, and meanwhile, the labor intensity of doctors is reduced.

Description

Technical field [0001] The present invention relates to the field of medical imaging techniques, and more particularly to high-efficiency precision division methods for ultrasound positioning tumor images. Background technique [0002] Ultrasound medicine is a discipline that combines acoustics, medicine, optical and electronics. Any study of acoustic technologies above audio-listening frequencies is ultrasonic medical, including ultrasound diagnosis, ultrasonic therapeutics and biomedicine. Therefore, ultrasonic medicine has the characteristics of medical treatment, reason, and work, which is widely involved, and has a high value in prevention, diagnosis, treatment of diseases. [0003] The precise division of the lesion area of ​​the ultrasonic image is of great significance and application value. It can guide the treatment probe to focus high-intensity ultrasound to the lesion area, which can improve the treatment effect, and avoid damage to other organizations. Under normal c...
