The invention provides a TIMI myocardial perfusion frame number obtaining method. The TIMI myocardial perfusion frame number obtaining method comprises the steps of: obtaining a coronary angiography image; determining a contrast agent conduction starting moment by using a deep learning network model; determining a contrast agent conduction termination moment by using the deep learning network model; and obtaining the number of frames between the conduction starting moment and the conduction ending moment. According to the TIMI myocardial perfusion frame number obtaining method, the conductionstarting moment and the conduction ending moment of a contrast agent can be determined through the deep learning network model; operation efficiency is high; and errors are not prone to happening.
Description
technical field [0001] The invention belongs to the field of image recognition and relates to a frame counting method, in particular to a TIMI myocardial perfusion frame number acquisition method, medium and electronic equipment. Background technique [0002] Coronary blood flow velocity is an important index of coronary blood flow reserve, which is of great significance for evaluating myocardial perfusion. Traditional methods for measuring coronary blood flow, such as intracoronary ultrasound Doppler and single photon emission tomography, are often limited by various conditions in practical applications and are difficult to be widely used in clinical practice. Recently, the TIMI (Thrombolysis in Myocardial Infarction) myocardial perfusion frame count (TIMI myocardial perfusion frame count, TMPFC) method has been widely used in clinical practice to measure coronary blood flow velocity due to its simplicity and convenience. To achieve the evaluation of myocardial perfusion. ...
