Introduction to Medical Imaging Physics and Technology

Medical imaging is at the heart of modern healthcare, transforming how we diagnose and treat diseases. This course offers a clear, accessible entry point into the fascinating physics and engineering that make these technologies possible. You will journey through the foundational science of both ionizing and non-ionizing radiation, learning how physical signals are captured and reconstructed into clear clinical images. By reading our structured explanations and working through practical written exercises, you will develop a strong conceptual grasp of the field. What you'll learn: - Understand the fundamental terminology of tomographic imaging and key image quality metrics. - Explore the physics of ionizing radiation as applied to X-ray systems and Positron Emission Tomography (PET). - Master the engineering principles of non-ionizing modalities, including Magnetic Resonance Imaging (MRI) and ultrasound. - Learn the mathematical foundations of image reconstruction, such as filtered backprojection and modern digital processing. - Analyze safety protocols, radiation doses, and modern clinical standards for patient care. The course begins with foundational concepts of wave and particle physics before guiding you step-by-step through individual imaging modalities and modern digital reconstruction techniques. It is designed for beginners, aspiring medical physicists, biomedical engineering students, and healthcare professionals seeking a solid technical foundation with no prior imaging experience required.
