Course Introduction
Radiologic Science is an interdisciplinary course that introduces students to the principles and applications of medical imaging technologies used in the diagnosis and treatment of diseases. The course covers foundational topics such as human anatomy and physiology, radiation physics, radiographic imaging procedures, radiation protection, and patient care. Students explore various modalities, including X-ray, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound, learning about image production, quality assurance, and safety protocols. Emphasis is placed on ethical considerations, effective communication, and the role of radiologic technologists within healthcare teams. This course prepares students for further study or entry-level roles in the radiologic sciences field.
