摘要：

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 rime. Here we report the design considerations that led to these improvements.
