Abstract

The invention provides a device for detecting conditions of an inner support adhering wall of a coronary artery. The device comprises an image obtaining unit, for obtaining optical coherence tomography images in the coronary artery; a support position calculating unit, for calculating the position of the support in each optical coherence tomography image; an inner wall position calculating unit, for calculating the position of the inner wall of the coronary artery in each optical coherence tomography image; an adhering wall condition determining unit, based on the positions of the support and the inner wall of the coronary artery in each optical coherence tomography image, for determining the conditions of the adhering wall between the support and the inner wall of the coronary artery; and an image outputting unit, according to the conditions of the adhering wall between the support and the inner wall of the coronary artery, for generating and outputting the images for reflecting the conditions of the adhering wall of the inner support of the coronary artery. The device is capable of, based on the intravascular optical coherence tomography (IVOCT) image, rapidly and automatically providing the visual and quantitative conditions of the support adhering wall for the percutaneous coronary intervention.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for detecting the adhering condition of a stent in a coronary artery. Background technique [0002] Coronary heart disease, also known as coronary atherosclerotic heart disease, is mainly caused by the accumulation of fatty substances and atherosclerotic plaques in the walls of coronary arteries. At present, the most important method to treat coronary heart disease is percutaneous coronary intervention, which is to place a stent in the narrowed or blocked coronary artery, and use the stent to stretch the blood vessel to improve the blood circulation in the blood vessel. However, at present, in the clinical operation of placing stents, due to the low resolution of X-ray contrast images, it is impossible to clearly know the situation of stent placement at all. However, once the stent is placed poorly, the stent does not fully adhere to the inner wall of the corona...
