Portable 3D/4D Ultrasound Diagnostic Imaging System (PUDIS)

PUDIS is a Portable 4Dimensional Ultrasound Diagnostic Imaging System with a single 2D phased arrayprobe. A 3D adaptive beamforming procedure is implemented in an advanced ultrasound computing architecture. Up to 20 volumes per second are recorded and displayed to give a real time view inside the body at a full opening angle of 80 degrees (azimuth and elevation). An easy to use user interface in combination with a decision-support process provides the possibility for a rapid and automated diagnosis of internal injuries like bleeding or facilitates image guided surgery. The objective of this paper is to describe the technological implementation of PUDIS concerning the overall operating procedure, the computing architecture, the probe with multiplexer, the adaptive beamforming method and the automated diagnosis procedure.
