Embodiment Construction

[0012] A probe for detecting near-infrared breast tissue proposed by the present invention is characterized in that it includes: a multi-wavelength near-infrared light source and a multi-channel photodetector for receiving near-infrared light emitted by the light source and passing through the breast tissue. A wavelength light source is located on the opposite side of the topology formed by the photodetectors that detect near-infrared light emitted by the light source through breast tissue.

[0013] The working principle of the present invention is: a multi-wavelength light source sequentially emits light of different wavelengths, and the emitted light is incident and enters the breast tissue, escapes from the tissue after being transmitted in the breast tissue, and the photodetector located outside the tissue receives the light passing through the breast tissue. Light. The photodetector converts the detected light signal into a corresponding electrical signal and transmits it...

Abstract

A probe for NIR glandular tissue detection, which belongs to the field of glandular tissue detection technology, is characterized in that the probe comprises a multi-wavelength NIR light source and a plurality of photodetectors for receiving NIR light emitted by the multi-wavelength NIR light source; the multi-wavelength NIR light source is positioned on the opposite side of the topological structure constituted by the plurality of photodetectors at a distance as far as possible. The invention also provides an embodiment. In the invention, the straight line distance between the multi-wavelength NIR light source and each photodetector is increased in the small probe, so that the small probe can be used for detecting thicker glandular tissue and the detection volume is larger, thus improving the detection efficiency.

Description

technical field [0001] The invention belongs to the comprehensive technical field of application of near-infrared laser, computer, machinery, electronics and image processing in biomedicine. Background technique [0002] Breast disease is one of the frequently occurring diseases of women. In recent years, the incidence rate has increased, and it has become the first malignant tumor in women in my country. Therefore, the census and early diagnosis of breast tissue are very important. At present, Mammography or CR technology is mostly used for census and diagnosis. Although they have a high detection rate ratio, they are low in efficiency, high in cost, and harmful to the human body. Generally, X-ray, B-ultrasound and other imaging examinations need to have a certain density resolution. Only when the cancerous mass exceeds 2mm will it be visualized. When breast cancer occurs, it first occurs in the terminal ductal lobe of the breast. From atypical The change process from hype...
