Embodiment
[0047] In a specific embodiment, such as figure 1 , figure 2 and image 3 As shown, a detection system for upper extremity lymphedema after breast cancer surgery based on multimodal optical imaging technology includes a light source module, an image acquisition module and a host computer; the image acquisition module is connected to the light source module and the host computer ; The light source module includes a laser module and a white light module; the light source module also includes an astigmatism device.
[0048] The image acquisition module in this embodiment includes an image sensor and an imaging lens.
[0049] The astigmatism module is used to scatter the concentrated light beam so that it irradiates the body surface of the human body uniformly; the astigmatism module used in this embodiment is three astigmatism modules.
[0050] The image acquisition module in this embodiment is a Basler camera, the laser module is an 830nm laser machine, a white light module,...

The invention provides a breast cancer postoperative upper limb lymphedema detection system and method based on a multi-mode optical imaging technology. The breast cancer postoperative upper limb lymphedema detection system comprises a light source module, an image acquisition module and an upper computer, and the image acquisition module is connected with the light source module and the upper computer; and the light source module comprises a laser light source, a white light source and two single-wavelength LED light sources. Laser illumination is utilized, the image acquisition module is used for shooting an image, data of an image R channel are obtained through the upper computer, and the blood perfusion condition is calculated based on the laser speckle effect. The upper limb lymphedema detection system and method have the advantages that in upper limb lymphedema detection after the breast cancer operation, direct contact with a detected part of a patient is avoided, the optical detection principle is slightly affected by the external environment, and therefore the upper limb lymphedema detection system and method have the advantages of being high in sensitivity and reliability, high in anti-interference capacity and the like.
Description
technical field [0001] The invention relates to laser measurement and optical absorption technology and the medical field, in particular to a detection system and method for upper limb lymphedema after breast cancer surgery based on multi-modal optical imaging technology. Background technique [0002] Breast cancer-related lymphedema (BCRL) is the most common complication after radical mastectomy. According to the survey, the incidence of edema is as high as 16.6%. Once lymphedema occurs, it will plague patients for a long time, it is difficult to cure in a short time, and the harm to patients will gradually increase with swelling. Therefore, effective detection and evaluation in the early stage will reduce the incidence of postoperative upper limb lymphedema. Reduce the degree of edema and promote the recovery of patients. [0003] It is known that the cause of edema is mainly due to surgical resection of axillary lymph nodes or chemotherapy before and after surgery, resu...
