Abstract

The invention discloses an ultrasonic myocardial tissue multi-parameter imaging method and system, and the method comprises the steps: obtaining multiple groups of original channel data through employing a plurality of large-sound-domain divergent waves which rise and fall and are alternately transmitted from a myocardial tissue, carrying out the beam forming through employing a rapid beam forming method, and obtaining a plurality of pieces of radio frequency data after the beam forming, imaging parameter reconstruction is performed according to radio frequency data to obtain a myocardial tissue multi-parameter image, so that side lobe artifacts and phase delay interference coherent recombination caused by a large angle when the tissue rapidly deforms are improved, phase delay generated by rotation is eliminated, phase delay generated by tissue movement, alternating sequence and autocorrelation product combination are reserved, and a myocardial tissue multi-parameter image is obtained. The contrast ratio and the resolution ratio of the heart image are improved; and high-frame-rate and large-sound-domain ultrasonic myocardial tissue speed, displacement, instantaneous strain and accumulated strain images with up to 20 parameters are obtained.

Description

technical field [0001] The invention belongs to the field of ultrasonic imaging, and relates to a high-frame-rate divergent wave coherent compound heart ultrasonic myocardial multi-parameter elastic imaging technology, in particular to an ultrasonic myocardial tissue multi-parameter imaging method and system. Background technique [0002] As an imaging method with the highest frame rate in medical imaging, ultrasound has the advantages of real-time, no radiation, and bedside detection. It is often used as a means of cardiac structure and function imaging. High frame rate imaging of the heart is of great significance for heart detection. However, the heart is in fast motion (resting state heart rate is about 60bpm, and the stress state is above 120bpm) which is difficult to be well characterized by traditional imaging methods. [0003] In traditional echocardiography, there is a contradiction between frame rate and sound field. Traditional echocardiography uses focused waves...
