Title: "RadPosi: Introduction to Medical Terminology and Radiographic Positioning Basics"
Description: This session introduces the foundational concepts of medical terminology and basic radiographic positioning techniques. Understanding medical terms is essential for effective communication in radiology, as it provides the language to describe anatomy, procedures, and imaging processes accurately. The session also covers the principles of patient alignment, image quality, and the proper use of equipment, all of which are essential for producing diagnostic images and ensuring patient safety during imaging procedures.
