Imaging the Surgeon May Use
Captions available
The idea
Four imaging methods matter most in surgery: X-ray, computed tomography, magnetic resonance imaging and ultrasound.
In practice
X-rays use ionizing radiation for flat images; computed tomography combines X-rays into cross sections; magnetic resonance uses magnetic fields and radio waves; ultrasound uses sound waves.
Where people slip
X-ray and computed tomography expose people to radiation, a hazard covered in unit eight.
