Patent number: 12004903Abstract: 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: GrantFiled: October 24, 2019Date of Patent: June 11, 2024Assignee: 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
