| 摘 要： | 为了评估3 GHz微波热声成像系统的性能,采用圆形扫描的探测方式,对不同形状、不同对比度以及埋在猪肉脂肪中不同深度处的仿体进行了热声成像实验.仿体实验结果表明,该系统对具有不同对比度的10 mm×20 mm的矩形吸收体、边长8 mm的正方形吸收体以及直径8 mm的圆形吸收体能够清晰地成像,系统的空间分辨率和成像深度分别为2和5 cm.

| 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. |
