Intravascular ultrasonic image construction method and device, ultrasonic equipment and storage medium

Abstract

The invention discloses an intravascular ultrasound image construction method and device, intravascular ultrasound equipment and a computer readable storage medium. The method comprises the steps: acquiring line data in each frame of the cross section image of an intravascular ultrasound image, and processing the line data into to-be-displayed line data; storing the to-be-displayed line data and acorresponding longitudinal section identifier according to the longitudinal section corresponding to the to-be-displayed line data and a preset data structure; and reading target to-be-displayed linedata corresponding to a target longitudinal section identifier according to a received section display command, and displaying the target to-be-displayed line data as a target longitudinal section image. Therefore, according to the construction method of the intravascular ultrasound image, the construction efficiency of the intravascular longitudinal section image is improved.

Description

technical field [0001] The present application relates to the technical field of ultrasound imaging, and more specifically, to a method and device for constructing an intravascular ultrasound image, an intravascular ultrasound device, and a computer-readable storage medium. Background technique [0002] Intravascular ultrasound (intravenous ultrasound, IVUS) refers to the combination of non-invasive ultrasound technology and invasive catheter technology, using a special catheter with an ultrasonic probe connected to the end of the medical imaging technology. At present, doctors mainly use the long-axis imaging method to read IVUS images. For a historical image with 9000 frames, taking 512 lines and 580 points per line as an example, the amount of IVUS data that needs to be stored in the storage space is: 512×580 ×8×9000=2548MB, based on the mechanical hard disk reading and writing speed of 150MB / s, the reading time takes more than 16 seconds, plus the time of digital signal ...
