Patent number: 11759177Abstract: A three-dimensional ultrasound tomography method and system based on spiral scanning are provided. The method includes the following. (1) Collecting raw data: an emission array element is switched while a probe maintains a uniform linear motion, so that changes in trajectory with time of a position of an equivalent emission array element in a three-dimensional space show a spiral or a partial spiral, and echo data is received. (2) Pre-processing data. (3) Calculating coordinates of each equivalent emission array element. (4) Calculating coordinates of an imaging focus point. (5) Performing synthetic aperture focusing on each imaging focus point. (6) Post-processing data. The disclosure improves the principle of the imaging method, the design of the overall process, etc. Volume data containing information of continuous tissue layers is obtained through spiral scanning.Type: GrantFiled: May 15, 2020Date of Patent: September 19, 2023Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Ming Yuchi, Mingyue Ding, Zhaohui Liu, Qiude Zhang, Junjie Song, Shanshan Wang, Liang Zhou, Kuolin Liu

Publication number: 20210386398Abstract: A spiral ultrasonic tomography imaging method and system are provided. The method is to use synchronous rotation of an ultrasonic probe or cyclic switching of emission array elements in the ultrasonic probe under the premise of a uniform displacement of the ultrasonic probe along the Z axis, so that the change trajectory of the positions of emission array elements over time in a three-dimensional space at each ultrasonic emission time is distributed along a spiral line or a curve. During the process of the uniform displacement of the ultrasonic probe along the Z axis, the ultrasonic probe emits ultrasonic waves and receives and collects echo data. The collected echo data is stored and post-processed to realize ultrasonic tomography imaging of an object. The spiral ultrasonic tomography three-dimensional scanning method and the corresponding system realize rapid continuous uninterrupted data acquisition to ensure that higher spatial resolution in the Z-axis direction.Type: ApplicationFiled: October 24, 2019Publication date: December 16, 2021Applicant: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Ming YUCHI, Mingyue DING, Qiude ZHANG, Junjie SONG, Kuolin LIU, Zhaohui LIU, Liang ZHOU, Zhaohui QUAN, Xiaoyue FANG, Yun WU, Quan ZHOU

Patent number: 10853941Abstract: The present invention discloses a registration method and system for a non-rigid multi-modal medical image. The registration method comprises: obtaining local descriptors of a reference image according to Zernike moments of order 0 and repetition 0 and Zernike moments of order 1 and repetition 1 of the reference image; obtaining local descriptors of a floating image according to Zernike moments of order 0 and repetition 0 and Zernike moments of order 1 and repetition 1 of the floating image; and finally obtaining a registration image according to the local descriptors of the reference image and the floating image. In the present, by using self-similarity of the multi-modal medical image and adopting the Zernike moment based local descriptor, the non-rigid multi-modal medical image registration is thus converted into the non-rigid mono-modal medical image registration, thereby greatly improving its accuracy and robustness.Type: GrantFiled: October 9, 2016Date of Patent: December 1, 2020Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Xuming Zhang, Fei Zhu, Jingke Zhang, Jinxia Ren, Feng Zhao, Guanyu Li, Mingyue Ding
