Abstract
Method and apparatus for 3D/4D ultrasonic imaging. An array of ultrasonic sources and receivers (7) positioned over or near tissue (6) transmit short encoded omnidirectional ultrasonic shots (9). The amplitude and phase of the resulting reflected waves (10) are detected, sampled and digitised. Traces from each shot are reconstructed by digital data processing. A three dimensional data volume is constructed corresponding to reflection amplitude through a regular volume. The data volume may then be imaged through any arbitrary plane. Time varying images can be readily produced as the process takes only a fraction of a second.
