Abstract
We have previously developed instrumentation for performing thermoacoustic computed tomography (TCT) of the human breast using 434 MHz radio waves. Recently, we have modified our original TCT scanner design in a number of important ways. We have increased the number of ultrasound detectors and decreased their size, and we have replaced our single RF wave- guide with a phased array of eight wave-guides. These modifications have led to increased spatial resolution, increased imaging field of view, and decreased scan time. Here we report the design considerations that led to these improvements.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
