Austra & Lian Journal of Basic Sciences, 2022

Abstract

Physics has played a fundamental role in the development and refinement of medical technologies, offering groundbreaking diagnostic and therapeutic tools. From the principles of electromagnetism in MRI to nuclear physics in PET scans, and from radiation therapy based on particle physics to cutting-edge laser and nanotechnology-based surgical techniques, the interplay between physics and medicine continues to evolve. This paper explores how physics-based innovations have transformed modern healthcare, improving patient outcomes and enabling precision medicine. It also highlights emerging areas like quantum imaging and nanophotonics that promise to further revolutionize clinical practice.
