Problems solved by technology

However, the single-wavelength light obtained through the double filter requires two cameras to obtain, and the two cameras cannot be at the same position, and the angle is deviated, so there must be errors in the data obtained in this way; moreover, the pass through of the filter The light efficiency is not necessarily exactly the same, and it cannot be controlled
Therefore, if computer image post-processing is performed based on such data, it is difficult to guarantee the reliability of the obtained blood and oxygen content detection results, and it is still difficult to meet the requirements of improving the diagnostic accuracy rate of breast diseases

Embodiment Construction

[0034] The present invention will be explained in detail below in conjunction with the description of the drawings and the clinical examples of specific embodiments.

[0035] We know that when light passes through a homogeneous medium with light-absorbing substances, its light intensity is weakened. The fraction of molecules absorbed depends only on the number of molecules present in the optical path, and has nothing to do with the intensity of incident light. If parallel monochromatic light with intensity I passes through a very thin layer of medium, the transmitted light intensity can be obtained by the Lambere-Bere law

[0036] I=I 0 exp[-KL]

[0037] where I 0 ——incident light intensity

[0038] I - transmitted light intensity

[0039] L - layer thickness through the medium

[0040] K——Extinction Coefficient or Absorptio...

Abstract

Mammary gland blood oxygen function imaging method and system is disclosed. The method includes irradiating mammary gland tissue with a double wavelength light source, receiving light with a detector, converting the analog signal of light strength into digital signal, performing image processing to calculate the variation in oxyhemoglobin and deoxyhemoglobin, and final mapping the the variation in oxyhemoglobin and deoxyhemoglobin to form figure. The system features its double wavelength generator connected to the light source controlling module, and its image analysis and processing system connected to the computerized central processing system. Using the imaging method and system can obtain sufficient and accurate image data for post computer image treatment and obtain raised diagnosis coincidence rate.

Description

technical field [0001] The invention relates to an infrared imaging method and equipment manufactured for realizing the method, in particular to a breast blood oxygen functional imaging method and a breast blood oxygen functional imaging system applicable to breast disease diagnosis. Background technique [0002] Breast cancer is a malignant tumor of breast epithelial tissue. Like other cancers, it starts with abnormalities in cells. Cancer cells are different from normal cells. One of its characteristics is uncontrolled reproduction, dysplasia, lack of normal mature cell functions, wanton invasion of adjacent tissues, and damage to the structure and function of normal tissues. Another feature of cancer cells is low adhesion, which can detach from the tumor and transfer to distant tissues or organs through blood vessels or lymphatic vessels. Therefore, in the advanced stage of breast cancer, not only the lesions of local lesions on the breast and chest wall are quite seri...
