Image acquisition system for breast cancer diagnosis equipment

Abstract

The invention discloses an image acquisition system for a breast cancer diagnosis equipment. The image acquisition system for the breast cancer diagnosis equipment comprises a mounting rack, an LED light source which is arranged on the mounting rack and used for producing infrared light, and an image acquisition module which is arranged on the mounting rack and at the upper portion of the LED light source and is used for receiving the infrared light which is emitted by the LED light source and penetrates the examined breast; the image acquisition module comprises a CCD vidicon used for shooting dynamic images and an air bag used for compressing the breast. Uniform distributed pressure can be exerted on the breast by the image acquisition module through the air bag, so that the blood content and the deoxygenated hemoglobin can be driven to produce obvious changes, and therefore mammary gland malignant lesion characteristics detected by adopting the two features of the blood content and the deoxygenated hemoglobin is 6-8 years earlier than that detected by the traditional imaging methods.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a special device for diagnosing breast cancer. Background technique [0002] In the scientific community, the process of neovascularization has been shown to be directly linked to the growth and progression of most cancers, as well as to more than 70 other human diseases. [0003] Neovascularization is a key biological process that occurs in healthy and diseased tissues. Under normal conditions, neovascularization is essential for regeneration, embryonic development and wound repair. Under these conditions, a complex process of neovascularization maintains a delicate balance. This balance is accomplished by a variety of neovascularization stimulating growth factors, cardiovascular inhibitors, cell assembly molecules, extracellular matrix and other regulatory factors. However, when this balance is disturbed, too many or too few new blood vessels are produced, leading to vario...

Problems solved by technology

[0004] Due to the relatively uniform low-absorption optical properties of breast tissue and the significant optical contrast mechanism provided by the angiogenesis effect of cancerous tissue, such as increased hemoglobin concentration and decreased oxygen saturation, optical breast tomography has the advantages of sensitivity, specificity and safety. Compared with traditional anatomical imaging modalities such as X-ray, magnetic resonance and ultrasound, it has potential comprehensive advantages. Most of the existing optical diagnostic methods only image the optical or fluorescence properties of the tissue: for example, blood oxygen diffusion optical tomography can in principle obtain the intrinsic physiological characteristics used to distinguish the degree of tissue benignity, but due to its serious inverse problem The morbidity of the method and the limitation of relying on the endogenous contrast, this method has the disadvantages of insufficient precision and large artifact interference in practical applications; fluorescence diffusion optical tomography relies on the pharmacokinetic properties of fluorescent agents between diseased and normal tissues The exogenous contrast enhancement (2 to 4 times) mechanism provided by the significant difference between the two can obtain tumor location information more reliably, but cannot obtain the intrinsic physiological characteristics of the tissue
