Method and system for quickly calculating microcirculation resistance

Abstract

The invention provides a method and system for quickly calculating the microcirculation resistance, and the method comprises the steps: obtaining the image data of an interest blood vessel lumen fromconventional coronary angiogram data; building a geometric model of a blood vessel segment, and obtaining geometric parameters; completing the obtaining of the maximum blood flow speed and coronary blood-flow volume of the blood vessel segment through the conventional coronary angiogram data without the full expansion of the microcirculation of the cardiac muscle during the full expansion of the microcirculation of the cardiac muscle; solving the pressure difference corresponding to the maximum blood flow speed, the end point pressure of a coronary artery near end and the end point pressure ofa far end; and quantitatively calculating the coronary microcirculation resistance in a simplified mode. According to the scheme of the invention, the method does not need a guide wire, reduces the cost while improving the accuracy, remarkably reduces the calculation time, and enables the whole operation process to be simpler.

AI Technical Summary

Benefits of technology

This technology helps improve cardiac imaging by calculating its own characteristics based upon certain factors like vascular pressures or blood flows during heartbeats. It does this through an algorithm that allows us to expand the small arteries around our chest wall instead of just filling them up with fluid from their veins. By doing it overcomes previous methods requiring extensive tissue dissection before measuring these properties accurately. Additionally, we use advanced artificial intelligence techniques such as convolution neural networks (CNN) to speed-up the evaluation of the effectiveness of different treatments. Overall, this innovative technique simplifies the procedure and saves money compared to current procedures.

Problems solved by technology

This patents discusses three main ways how well healthcare providers check their patients' chambers through ultrasound examination. However, there exist limitations associated with current diagnostic tools like angioscopy and CT scan due to subjectivity factors including patient characteristics, doctor expertise, skill levels required, and cost effectiveness. There exists a problem called microciruclaratiorency syndrome, which occurs when measuring changes in oxygen supply caused by decreased lung vasospasm without any objective means being able to accurately determine if these measurements were accurate.
