Sažetak
In this paper, the frequency spectra of the CUSA (Cavitation Ultrasonic Surgical Aspirator) probe at its working frequency of 25 kHz were measured in an oval container (simulating the cranium). The measurement was made at few field intensities, using the B&K hydrophone in the container, and the B&K microphone outside it. Cow brain tissue, physiologically similar to human brain was used as a dummy model. The same measurement was repeated in water to examine the spectrum difference in high and low attenuation media. During the measurement, the occurrence of the cavitation was observed by spectra changes.
