Positioning method and positioning system for breast lesion puncture point

Abstract

The invention discloses a positioning method and a positioning system for a breast lesion puncture point. The positioning method comprises the following steps of: acquiring breast images shot at two different angles by a bulb tube of an X-ray digital mammography machine, and establishing a lesion projection light cone to generate a puncture guide body model. The maximum cross section is obtained by using a plane cross section guide body of a detector which is parallel with the X-ray digital mammography machine, and a point which is far away from the edge is picked on the maximum cross section to serve as the puncture point. The puncture point determined by the positioning method is located in a breast lesion, and is remote from the edge of the lesion, and more enough lesion tissues can be obtained when puncture biopsy is performed. Compared with other puncture point coordinate computing methods, the positioning method for the breast lesion puncture point has the advantages that puncture point computation is exquisite; the theory is perfect; the result accuracy is higher; the operation is simple; and the computing speed is high.

Description

technical field

[0001] The invention relates to the technical field of mammary gland detection, in particular to a method and system for locating puncture points of mammary gland lesions. Background technique

[0002] In order to prevent and alleviate the harm of breast disease to women's health, it is necessary to use accurate detection methods to correctly diagnose the disease, and it is easy to take timely treatment measures. At present, breast disease detection methods include: X-ray mammography breast detection, X-ray digital breast detection, ultrasonic breast detection and magnetic resonance breast detection, among which, X-ray breast detection is the most commonly used detection method and is the most common method of breast detection. gold standard.

[0003] Accurate detection of small lesions (<10mm) can detect breast cancer early, treat breast cancer as early as possible, and prolong women's life, but it is difficult to make an accurate diagnosis through imagi...
