Medical image processing device

Abstract

The medical image processing device includes: a centerline analysis and processing unit (15), which extracts at least two coronary artery centerline structures from data of at least two images related to the heart and corresponding to at least two heartbeat time phases, in order to generate Coronary artery centerline structures corresponding to multiple heartbeat time phases in one heartbeat, interpolating coronary artery centerline structures involved in other heartbeat phases based on at least two extracted coronary artery centerline structures; displacement distribution A calculation unit (19) calculates a plurality of displacement distributions between each heartbeat phase based on a plurality of coronary artery centerline structures covering one heartbeat.

Description

technical field [0001] Embodiments of the present invention relate to a medical image processing device. Background technique [0002] As is well known, in ischemic heart disease, blood flow to the myocardium is obstructed due to occlusion or stenosis of the coronary arteries, and the supply is insufficient or interrupted, thereby causing disturbance in the heart. As a symptom, there is pain, pressure, mainly in the front chest, sometimes in the left wrist or back. [0003] FFR (Fractional Flow Reserve: Fractional Flow Reserve) is an index for determining whether the myocardium is in an ischemic state due to coronary artery stenosis. like Figure 9 As shown, a pressure guide wire is inserted into the blood vessel of the subject, and Pin, which is the upstream pressure of the stenosis, and Pout, which is the downstream pressure, are measured. Defined by FFR=Pout / Pin. [0004] In general, in most cases, surgical treatment (catheter surgery: PCI) is required when the FFR val...

AI Technical Summary

Problems solved by technology

[0007] However, in simulation-based measurement, time-series volume data covering at least one heartbeat is required, and therefore a lot of work and time are spent on imaging and data analysis

In addition, in the heartbeat phase when the heart is moving fast, the coronary arteries may sometimes be blurred, and errors may be included in the data.
