Saskia Camps is a biomedical R&D engineer at the Swiss startup EBAMed. EBAMed develops and commercializes innovative solutions that allow for non-invasive treatment of cardiac arrhythmias using proton beams. Before joining EBAMed, Camps earned her PhD at the Eindhoven University of Technology in a collaboration with the Maastro Clinic (Maastricht, the Netherlands) and Philips Research (Eindhoven, the Netherlands). The focus of her PhD work was on automation of ultrasound image acquisition and interpretation for dose guidance in prostate cancer radiotherapy workflows. Davide Fontanarosa is a physicist with a solid background in ultrasound imaging and medical physics. He worked in one of the top institutions for radiation therapy (MAASTRO Clinic, in the Netherlands) and in one of the largest industrial research laboratories in the world, Philips Research, as a Senior Scientist. Then he moved to Queensland University of Technology (Brisbane, Australia) where he is currently working as an Associate Professor and doing research in several fields related to ultrasound, imaging techniques and radiation therapy. Emma Harris is a Reader of imaging and radiation physics at the Institute of Cancer Research in London, UK. Her research focuses on the application of radiation physics, ultrasound physics engineering and image processing to improve radiotherapy. She has spent more than a decade leading experimental studies of image guided radiotherapy and has devised and conducted a number of clinical studies investigating the use of ultrasound for image guidance of radiotherapy of cervical cancer, prostate cancer and paediatric cancers.  Frank Verhaegen is a Professor at the University of Maastricht (the Netherlands) and head of the physics research division of Maastro Clinic, a radiotherapy facility with photon, electron and proton beams. Before that, he was an Associate Professor at McGill University (Montreal, Canada). He is specialized in image guidance and dose calculations for radiotherapy. Both at Maastricht and Montreal he performed several research projects with medical companies developing novel 3/4D ultrasound imaging devices for radiotherapy. He is the co-author of several studies and review papers in this field.
