A Novel Ultrasound Imaging System Based on Endoscopic Array Probe

Abstract:

A novel ultrasound imaging system based on endoscopic array probe is presented in this paper. The system utilizes an endoscopic linear-array probe instead of the conventional single-element probe to implement ultrasound scanning in vivo. For the system, a micro linear-array ultrasound probe sized Φ10mm×20mm is firstly designed. And then the excitation circuit, gating circuit and echo receiving and processing circuit are all designed cored by a center control unit FPGA. Finally the research of d/2 focusing algorithm is implemented on the basis of the system. After processed, the gray image of echoes reflected by a glass jar’s wall is obtained and shown on a computer.
