Image fusion method for detecting peripheral vascular obstructive diseases

Abstract

The invention discloses an image fusion method for detecting peripheral vascular obstructive diseases. The method comprises: in a first part, using a near-infrared II-region fluorescent blood vessel imaging technology and a laser speckle blood flow imaging technology for obtaining two heterologous images; in a second part, using an image fusion method for carrying out operation on the two images output in the last step; wherein the third part is used for positioning a concerned blood vessel in the living blood vessel information image, calculating indexes for reflecting the health condition ofthe blood vessel, mainly the blood vessel diameter stenosis rate and the blood flow velocity, and finally detecting whether the blood vessel is blocked or not according to the indexes. The advantageinformation and complementary information of the static blood vessel image and the dynamic blood flow image are organically combined, the part and the condition of vascular occlusion lesion can be well displayed, and other reasons causing limb swelling or pain, such as hematoma, vein compression and the like, can be found out. The development condition of the disease of the patient can be effectively evaluated, and corresponding treatment is provided for clinic.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image fusion method for detecting peripheral vascular obstructive diseases. Background technique [0002] Common detection methods for peripheral vascular occlusive disease include venography and color Doppler ultrasonography. The former is invasive diagnosis, difficult to operate, and will have a great impact on the patient's psychology; the latter is an auxiliary diagnosis and treatment method. Although non-invasive, there is still a certain false detection rate. In this field, the existing patents include Chinese invention patent 201811298696.5 "A device and method for evaluating the degree of vascular stenosis in peripheral arterial disease", which uses a modular method to accurately evaluate the degree of peripheral arterial vascular patency, but there are shortcomings is the lack of imaging capabilities. [0003] The present invention is based on an image fusi...
