This workshop session will examine the physics involved in the specialised fields of sonography, endoscopy and interventional radiology.

Sonography, also known as ultrasonography, is an imaging technique that utilises high frequency sound waves to visualise organs, tissues and blood vessels in the human body. The echoes reflected by different tissues are detected and processed to form the ultrasound image.

Endoscopy is a procedure where a long and thin tube, attached with a light and camera, is inserted directly into the body to examine an internal organ or tissue in detail. Endoscopes can be inserted through the natural openings of the body, such as the mouth or anus as well as small incisions.

Interventional radiology is a sub-specialty of radiology that uses imaging techniques such as fluoroscopy, CT, Magnetic Resonance Imaging (MRI) and ultrasound to guide procedures that diagnose and treat a growing list of medical conditions. The procedures in interventional radiology are minimally invasive, allowing patients to experience less pain and to recover faster.
