Characterization data P4-1 transducer

This dataset contains characterization data of the P4-1 medical ultrasound transducer present at the Physics of Fluids group, University of Twente. The data is used as example data for the characterization pipeline published in the GitHub repository PROTEUS-SIM/transducer-characterization. With the dataset published here and the code in the GitHub repository, the results in arXiv:2509.22090 can be reproduced.
