Conclusion: These results highlight the potential of volumetric ULM and P-ULM for proton range verification. However, improving the image processing workflow is required to increase the specificity against background microbubble flow and enable accurate 3D dosimetry with ULM.

Keywords: proton range verification, ultrasound imaging
