Diagnostic ultrasound is a widely used, indispensable diagnostic imaging modality that does not use electromagnetic radiation. An understanding of the physics of ultrasound is important because it helps explain some of the limitations of the modality and the artifacts encountered. In this chapter, the ...

PINNs take advantage of the governing physical laws behind the processes that generate the data, hence reducing greatly the reliance of the DNN on the labeled data during the training process. PINNs simply bridge the gap between data-scarcity and the data-intensive nature of DNNs and have been ...
Ultrasound imaging is widely used in obstetrics to monitor fetal development, as well as in cardiology to assess heart function. 2. Radiation Therapy: Physics plays a significant role in radiation therapy, a common treatment for cancer. Different techniques, such as external beam radiation therapy ...
The use of deep learning in medical imaging has increased rapidly over the past few years, finding applications throughout the entire radiology pipeline, from improved scanner performance to automatic disease detection and diagnosis. These advancements h
