Three-dimensional ultrasonic positioning and surgery navigation system as well as image processing method thereof

Abstract

The invention discloses a three-dimensional ultrasonic positioning and surgery navigation system. The three-dimensional ultrasonic positioning and surgery navigation system comprises an ultrasonic probe, wherein an infrared probe is arranged on the ultrasonic probe; and non-collinear three small infrared balls are mounted on the infrared probe. The three-dimensional ultrasonic positioning and surgery navigation system further comprises an infrared positioning device for positioning the infrared probe by measuring the positions of the small infrared balls; and the ultrasonic probe, the infrared probe and the infrared positioning device are connected with a computer. The invention further discloses an image processing method of the three-dimensional ultrasonic positioning and surgery navigation system. The image processing method can be used for virtually displaying three-dimensional scenes, such as a breast, a breast tumor, a puncture needle, and a surgery path, through data establishment and update, elastic registration and virtual reality. The three-dimensional ultrasonic positioning and surgery navigation system provided by the invention carries out data treatment after collecting data through ultrasonic waves and the infrared probe, is used for accurately positioning the breast by using the ultrasonic waves and infrared positioning, is used for diagnosing breast diseases, and further can be used for navigating breast puncture and surgery.

Description

Technical field [0001] The invention relates to a medical device, in particular to an ultrasonic image processing system and an image processing method of the system. Background technique [0002] At present, there are several examination methods for breast tumors in China: ① physical examination, ② mammogram X-ray, ③ ultrasound, ④ infrared scan, ⑤ puncture, ⑥ biopsy, ⑦ Others: including CT, MRI. In the past, the diagnosis of breast tumors mainly relied on X-ray photography. X-ray mammography can find occult lesions including occult breast cancer, and can perform stereotactic needle biopsy. However, the mammary glands of middle-aged and young women are mostly dense, and the contrast between fibroadenoma and surrounding tissues is not great. Therefore, mammography is not the preferred method for detecting benign breast tumors. Compared with mammography X-ray examination, ultrasound is not affected by tissue density, especially when dense breasts are accompanied by tumors, the con...

Problems solved by technology

[0005] In terms of surgical treatment, the Mammotome surgery in the United States is relatively advanced, but this technology only involves surgery, and the conventional B-ultrasound positioning method is still used
