Abstract
This paper describes a three-dimensional (3D) dynamic heart imaging system. In this system, ultrasound B-mode images are measured with a transesophageal probe, a 3D heart image at a given phase of the cardiac cycle is reconstructed with a volume rendering technique and image processing and a 3D dynamic heart image is presented by displaying the 3D static images sequentially in the cardiac cycle. Furthermore, a 3D heart image is divided into two regions with a section, and a B-mode image is reconstructed and superimposed on that section. Experimental results indicate that the system enables us not only to observe the motion of the myocardium, the mitral valve and so on from any point of view but also to observe the inside structure of the heart in detail using the 3D image and the reconstructed B-mode image.
