摘要

光声层析成像(OAT)利用短激光脉冲诱导的声波对肿瘤进行光吸收。宽频带换能器阵列检测光声信号的波形，提供肿瘤形状及其特异性的信息。将32单元声阵列应用于激光光声成像系统的临床样机中。压电聚合物PVDF薄膜用于阵列换能器的制作。本文讨论了阵列的灵敏度及其瞬态方向性方向图。在幻影实验中测试了该阵列的性能。

Wide-band acoustic pulse detection in opto-acoustic tomography system

The optoacoustic tomography (OAT) utilizes acoustic waves induced by short laser pulses in tumor with preferential light absorption. Waveform of the opto-acoustic signal detected by a wide-band transducer array provides information about shape of tumor and its specificity. The 32-element acoustic array was employed in clinical prototype of laser optoacoustic imaging system (LOIS). Piezopolymer PVDF film was used for the array transducer fabrication. Sensitivity of the array and its transient directivity pattern are discussed in this paper. The array performance was tested in experiments with phantoms.
