Abstract

A real-time 3D ultrasound system using Fresnel ring array is proposed. We have developed a prototype of a convex-convex shaped 2D-array probe with curvature of 40 mm for both in the lateral-axis direction and the elevational (vertical)-axis direction, and the center frequency is 3.5MHz. As a result, a transmitted beam profile measured in water is in good accordance with the theoretical simulation using FEM. By using the convex-convex shaped 2D array probe including a newly developed multiplex-IC, the dynamic focusing is performed with Fresnel ring, so that a good isotropic beam for scan can be obtained. A preliminary real-time 3D image has been demonstrated.
