摘要
Abstract
To evaluate the performance of a 3 GHz thermoacoustic tomography (TAT) system,absorbers with different shapes and contrasts were investigated using the circular scanning method,the imaging depth was probed into by adding porcine fat to the top of an absorber.Tissue-mimicking phantom experiment results show that the absorbers with different contrasts and shapes,i.e.,10 mm by 20 mm rectangle,8 mm square and 8 mm diameter circular absorbers,can be imaged,and spatial resolution and imaging depth of the system are 2 and 5 cm,respectively.关键词
