Introduction to fundamental principles of radiation physics, interaction with matter, and dosimetry for medical applications.
About this course
This course introduces the fundamental physics behind medical imaging. You will explore how radiation is produced, how it travels through matter, and how it interacts with the human body. The focus is on the principles that allow diagnostic images to be created while keeping patient exposure as low as reasonably achievable.
Topics include atomic structure, electromagnetic spectra, and the specific interactions of x-rays with tissue. You will also learn the basics of dosimetry, calculating the absorbed and equivalent doses to understand the biological implications of radiation exposure. This course lays the scientific groundwork for all subsequent imaging and radiation safety courses.
