This book reports on new trends, challenges and solutions, in the multidisciplinary fields of biomedical engineering and medical physics. Contributions spans from biomechanics, to robotic rehabilitation, radiation oncology, and image and signal processing, among many other topics. They cover advanced devices for diagnosis or patient monitoring, as well as for therapy (non-invasive surgery, rehabilitation and more). Gathering the proceedings of the 19th  Nordic-Baltic Conference on Biomedical Engineering and Medical Physics, NBC 2023, held on June 12–14, 2023, in Liepaja, Latvia, this book is expected to inform a wide audience of researchers, engineers and other professionals working in the broad field of biomedical engineering, and to offer a timely snapshot of research and projects that have been carried out within Nordic and Baltic countries, in particular, but not limited to them.
