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.
