Abstract

The invention discloses a method and device for measuring blood flow reserve fraction, wherein the method includes: obtaining the vascular characteristic parameters of the target patient's coronary artery, wherein the vascular characteristic parameters include the vascular cross-sectional radius at the set position, and the coronary artery Stenosis characteristic parameters of arterial vessel stenosis areas; inputting said blood vessel characteristic parameters into a pre-established fractional blood flow reserve measurement model to obtain fractional blood flow reserve of said target patient. The invention solves the problems of time-consuming measurement of blood flow reserve fraction and high requirement for equipment calculation, and can measure blood flow reserve fraction efficiently, accurately and in real time.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical image processing, and in particular to a method and device for measuring blood flow reserve. Background technique [0002] With the development of society and economy and the change of human life style, the morbidity and mortality of coronary artery disease show a significant upward trend, and the age of onset tends to be younger, which seriously threatens people's life and health. Prevention is urgent. At the same time, with the rapid development of modern technology and the in-depth research and exploration of medical science, the prevention, diagnosis and treatment of coronary artery disease have been fully developed. [0003] The currently popular technical means for diagnosis and evaluation of coronary artery lesions mainly include: coronary angiography, intravascular ultrasound, blood flow reserve fraction and other related technical means and evaluation indicators. A...
