Abstract

The work presents the development of a forward-looking 2D ring array for real-time volumetric endoscopic ultrasonic imaging using a novel rotary-dicing method. The completed array has an inner diameter of 3.5 mm, outer diameter of 5 mm, and 50 equal-area elements distributed concentrically. With a single front matching layer and a light backing, the array shows a center frequency of 3.5 MHz, a fractional bandwidth of 48%, insertion loss of -21.6 dB and cross-talk between nearest neighbor elements of 35.3 dB. The beam profile, two-dimensional pulse-echo point spread response, and phantom imaging of the array were studied with the Field-II simulation package. These promising results suggest that the rotary-dicing technology is an effective way to fabricate 2D ring array.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
