3D Dynamic Echocardiography with a Digitizer

概要

論文の詳細を見る
In this paper, a three-dimensional (3D) dynamic ultrasound (US) imaging system, where a US brightness-mode (B-mode) image triggered with an R-wave of electrocardiogram (ECG) was obtained with an ultrasound diagnostic device and the location and orientation of the US probe were simultaneously measured with a 3D digitizer, is described. The obtained B-mode image was then projected onto a virtual 3D space with the proposed interpolation algorithm using a Gaussian operator. Furthermore, a 3D image was presented on a cathode ray tube (CRT) and stored in virtual reality modeling language (VRML). We performed an experiment to reconstruct a 3D heart image in systole using this system. The experimental results indicate that the system enables the visualization of the 3D and internal structure of a heart viewed from any angle and has potential for use in dynamic imaging, intraoperative ultrasonography and tele-medicine.
