Abstract
This paper aims to highlight the pivotal role of physics in radiology, emphasizing its critical importance in both diagnostic and therapeutic applications. Radiology relies on a variety of imaging techniques, all of which are grounded in fundamental physical principles. These techniques include X-ray imaging, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). The paper provides an overview of the core physical principles underlying these technologies, discusses their applications in medical diagnostics and treatment, and underscores the importance of radiation safety and protection. Special attention is given to the role of medical physicists in the maintenance and calibration of equipment, treatment planning, as well as the training of medical staff.
