Understanding Medical Physics
Medical physics applies physics principles to healthcare, focusing on advancing techniques and technologies for health-related issues. This field encompasses various areas including radiation therapy, diagnostic imaging, and nuclear medicine, where medical physicists operate in hospitals and research facilities. Diagnostic imaging techniques like X-rays and MRIs play a crucial role, allowing non-invasive examination of the body. For example, X-rays use differential absorption, enabling distinct visualization of bones and soft tissues based on their ability to absorb radiation differently.
Advancements in Radiation Therapy
Radiation therapy is a significant aspect of medical physics, utilizing high-energy radiation to target and destroy cancer cells while protecting healthy tissues. Medical physicists employ dosimetry and brachytherapy to create precise treatment plans that maximize tumor dosage and minimize exposure to surrounding areas. The principles of radioactive decay and the inverse square law are essential here, ensuring effective radiation delivery. As technology progresses, techniques like particle therapy and hybrid imaging methods such as PET-CT are being integrated, enhancing the effectiveness and precision of cancer treatment.
