Abstract

The invention belongs to the technical field of medical devices, and particularly relates to a B-ultrasonic examination device based on canceration targeted positioning for early diagnosis of a breast cancer. According to the B-ultrasonic examination device based on canceration targeted positioning for early diagnosis of the breast cancer, photosensitive substances are guided into early tumors in a targeted mode through cancer targeted positioning, light energy absorbed by the photosensitive substances is converted into heat energy through infrared light irradiation, the temperature of tumor tissues containing the photosensitive substances rises, therefore, the ultrasonic transmission speed is changed, and acoustic impedance of the tissues is the product of density and sound speed; under a condition that the sound speed is changed, the acoustic impedance is changed along with the change of the sound speed, so that the change of echoes is caused, and the echoes are displayed in an ultrasonic image after being detected and processed by the B-ultrasonic examination device based on canceration targeted positioning, so that a B-ultrasonic inspection of early-stage cancer lesions is realized. The B-ultrasonic examination device comprises an ultrasonic detection head with an infrared emission function, an infrared light emission driver, a scanning controller, an ultrasonic receiver, a detector, a digital conversion DSC, an image processor, a display and the like. A powerful tool is provided for early diagnosis of the breast cancer.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a B-ultrasound examination device based on canceration targeting and positioning. Background technique [0002] At present, there are more than 10 kinds of methods for the diagnosis of breast diseases in clinical practice, but there are not many methods for the diagnosis of early breast cancer that are really mature or have good application prospects. At present, there are mainly: mammography, breast color Doppler ultrasonography, breast duct endoscopy, breast duct lavage, CT and magnetic resonance, etc. Among them, a large number of studies have confirmed that mammography is the main method of breast cancer screening recommended internationally in recent years. It can detect breast cancer with no mass in clinical examination. Women over 50 years old are sensitive. Sex is as high as 94%, 87% for 40-49 years old, and 77% for 30-39 years old. However, in the e...
