3D Ultrasound Data Acqusition System Based on Back End Scan Mode

The data acquisition of 3D-Ultrasound includes array scan and mechanical scan, and the later one is more easy to realize. Currently, the traditional probe scanning mode is Front-end scanning. Under the above scanning mode, when it scans over the breast, 2D-Ultrasound probe slides through the surface of the patients´ bodies, the image will be influenced strongly by the human ribs.In this paper we propose a new scanning mode to solve the above problem: Back-End scan, the back end rotates while the front end contacts the patients´ skin without slide. The device designed using dual stepper motors which are under the synchronization control. Experiment results show the effectiveness of the proposed device.
