Problems solved by technology

This measurement method assumes that the vessel diameter waveform and pressure waveform are the same, and uses arm pressure to calibrate, ignoring the difference between arm pressure and carotid artery pressure, resulting in inaccurate pressure assessment and affecting the measurement accuracy of wave intensity WI

Abstract

The invention is suitable for the technical field of image processing, and particularly relates to a cerebral artery wave intensity and wave power measuring method, terminal equipment and a computer readable storage medium. The measuring method comprises the following steps: acquiring a nuclear magnetic resonance image containing brain information and neck information, and constructing a cerebral hemodynamic model according to the nuclear magnetic resonance image; and obtaining target ultrasonic flow velocity frequency spectrum waveforms of the left internal carotid artery, the right internal carotid artery, the left vertebral artery and the right vertebral artery respectively, and determining the wave intensity and the wave power of each cerebral artery according to the cerebral hemodynamic model and each target ultrasonic flow velocity frequency spectrum waveform. According to the embodiment of the invention, the measurement of the WI and WP of the whole cerebral artery is realized in a mode of combining non-invasive measurement and numerical simulation, so that the accuracy of the measurement of the WI and WP of the cerebral artery is greatly improved, and the method has relatively high usability and practicability.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a method for measuring cerebral artery wave intensity and wave power, a terminal device, and a computer-readable storage medium. Background technique [0002] Cerebral arterial wave intensity (Wave intensity, WI) and wave power (Wave power, WP) are important markers to predict the risk of Alzheimer's disease. Therefore, measurement of cerebral artery WI and WP is required. At present, only common carotid artery WI measurements can be achieved, that is, a combined echo-tracking and Doppler system is used to simultaneously acquire common carotid artery diameter and flow velocity waveforms, which are estimated by calibrating the diameter waveforms to the systolic and diastolic pressures of the arm cuff The pressure waveform of the common carotid artery is obtained to calculate the WI of the common carotid artery. This measurement method assumes that ...
