Intravascular virtual endoscope imaging system based on electromagnetic positioning composite conduit and working method of system

Abstract

The invention relates to an intravascular virtual endoscope imaging system based on an electromagnetic positioning composite conduit and a working method of the system. The intravascular virtual endoscope imaging system comprises an electromagnetic positioning tracking module, a composite intravascular imaging conduit module and a positioning information processing and composite image presenting module, wherein the composite intravascular imaging conduit module is used for acquiring intravascular images; the electromagnetic positioning tracking module is used for acquiring a movement track of the composite intravascular imaging conduit module inside blood vessels, and used for transmitting the movement track to the positioning information processing and composite image presenting module, then correction and fusion of the intravascular images and the positioning information is implemented, and blood vessel spatial information is represented in a virtual endoscope environment. Relatively precise bases are provided for diagnosis on vasculopathy.

Description

technical field [0001] The invention relates to an intravascular virtual endoscope imaging system based on an electromagnetic positioning composite catheter and a working method thereof, belonging to the technical field of intravascular interventional imaging and diagnosis. Background technique [0002] According to my country's 2008 China Health Care Development Statistical Bulletin, cardiovascular disease is also the number one cause of death among urban and rural residents in my country, with an average of one person dying every 10 seconds, which is three times the death rate of cardiovascular disease in the United States. (1 death every 34 seconds)! The high morbidity and mortality of cardiovascular diseases have become an important factor restricting the social and economic development of our country. Recent studies have found that in most patients with acute cardiovascular and cerebrovascular events, atherosclerotic (AS) plaque rupture and thrombosis are the main patho...

Problems solved by technology

However, this patent has the following defects: the body surface three-dimensional ultrasound instrument used in the method described in this patent can only obtain images of superficial organs, and cannot realize imaging of deep blood vessels, such as coronary arteries and intracranial blood vessels, and cannot provide endoscopic imaging. In addition, CT or MRI and interventional catheters are needed to obtain the vascular skeleton first, then perform ultrasound imaging, and finally realize multi-step and multi-modal imaging of image matching

The actual operation of this patent needs to be carried out separately, that is, the use of body surface ultrasound for 3D reconstruction before operation, and the use of interventional catheters to obtain and match the path during the operation, which is complicated.
