Method, device and apparatus for reducing false positive rate in breast ultrasonic focus detection and medium

Abstract

The invention discloses a method for reducing the false positive rate of breast ultrasonic focus detection. The method comprises the following steps: tracking a suspected focus in a video by using a KCF tracking algorithm; extracting sub-videos according to a tracking result and preprocessing the sub-videos; inputting the preprocessed sub-videos into a CSN network for prediction; if the probability of the genuine yang category output by the CSN is greater than a preset threshold value, judging that the suspected focus is genuine yang, and if the probability of the genuine yang category output by the CSN is less than or equal to the preset threshold value, judging that the suspected focus is false yang. According to the method for reducing the false positive rate of breast ultrasonic focus detection provided by the embodiment of the invention, the inter-frame information is utilized to screen the results of the single-frame detection algorithm, so that the false positive rate is greatly reduced.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to a method, device, equipment and medium for reducing the false positive rate of breast ultrasonic lesion detection. Background technique [0002] At present, breast ultrasound is one of the main methods for breast disease screening in my country. It is painless and does not cause radiation damage to the examinee. It can be performed repeatedly in a short period of time. It is suitable for women of any age, including pregnant and lactating women. Breast exam. [0003] Breast ultrasound is to use an ultrasound machine to transmit ultrasound to the breast to obtain ultrasound images, and judge the nature of the lesion according to the display of the ultrasound images. Ultrasound videos are generated during breast scans, which are used for review by sonographers to determine whether there are lesions. [0004] In the prior art, most of the breast ultrasound lesion detection algori...
