Experimental Cavitation Monitoring Data using Protein Cavitation Nuclei and Focused Ultrasound

Calibrated array element signals (in units of Pa) received using an L7-4 linear array (ATL Ultrasound, Bothell, WA, USA), where cavitation was initiated in acoustically transparent sample containers using protein cavitation nuclei (pCaN) conducted on the 15th January 2026.

This dataset contains four .mat files, one for each sample of PCaN and one PBS control that was also exposed to the same ultrasound parameters. They contain the following variables:
fs: data sampling frequency [31.25 MHz]
t: Time axis of each pulse [s]
rf: array element signals (number of array elements, number of samples, number of pulses) [Pa]
c: speed of sound [1488.4 m/s]
pulseLength: time span of ultrasound pulse [10 ms]
recordLength: length of time for each rf recording [100 us]
elPos: positions of the centre of each array element [lateral, elevational, axial], [mm]

B mode images confirming sample container alignment are also included.
