Abstract
This paper describes a measurement technique specially developed to characterize optoacoustic sources in terms of their acoustic output. Attention is focused on laser assisted devices in which appropriately delivered light energy is converted into acoustic shock waves. A meaningful comparison of such devices with other therapeutic equipment designed for a direct interaction with tissue requires knowledge of the energy needed for a successful surgical treatment. It is demonstrated that knowledge of the key shock wave parameters allows the total acoustic energy associated with the shock wave to be determined. The procedure developed to calculate this energy is discussed and it is shown that the value of this energy can be conveniently used as an indicator of efficacy of an optoacoustic converter in a clinical environment. The influence of the performance of the PVDF hydrophone probes on the measurement results was also analyzed. It was determined that when appropriately selected, the wideband PVDF probes are well suited for characterization of the optoacoustic devices in the frequency range 1–100 MHz. The characterization procedure developed is applicable to surgical ultrasonic systems including conventional and laser assisted phacoemulsifiers.
