Embodiment Construction

[0062] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0063] like figure 1 As shown, the real-time wide-view ultrasonic imaging device of the present invention includes a wide-view image acquisition module, a wide-view image registration module, a wide-view image fusion module, and a wide-view image edge optimization module.

[0064] The panoramic image acquisition module acquires continuous sequence of ultrasonic image information, and selects two frames of image information in the continuous sequence, which are set as d frame and d+1 frame, and are transmitted to the panoramic image registration module.

[0065] Described panorama image registration module firstly carries out accurate corner point detection and determination with the image information of two frames before and after one step obtained in the previous step, gets the multi-corner points of two frames of im...

Abstract

The invention relates to a real time wide view ultrasonic imaging device and method. The method comprises the steps of acquiring an image, registering the image, fusing the image and carrying out edge optimization. The device comprises a wide view image acquisition module, a wide view image registration module, a wide view image fusion module and a wide view image edge optimization module. The method and the device which are provided by the invention have the advantages that ultrasonic image information of a continuous sequence is directly acquired from the image acquisition module for carrying out image registration and image fusion, the ultrasonic image information does not need to be acquired from a static video, then real time map making is realized by combining an efficient algorithm in the invention, and great help is provided for operation and diagnosis of a user.

Description

technical field [0001] The invention relates to the field of ultrasonic echo imaging, in particular to a real-time wide-view ultrasonic imaging device and method. Background technique [0002] Image wide-view imaging technology is a hot issue in the fields of multimedia, medical image processing and computer graphics recently. In the field of medical ultrasound imaging, it is the process of generating wide-view images using conventional scanning probes. Ultrasonic wide-view imaging is to stitch multiple two-dimensional slice images collected by moving the probe in the same plane to form a wide-field, high-resolution wide-view image, which is convenient for doctors to diagnose. [0003] Ultrasound image wide-view imaging technology is mainly divided into three main steps: image registration, image fusion and edge optimization. Image registration first extracts features from two images to obtain feature points; finds matching feature point pairs by performing similarity measu...
