The imaging potential of ultrasound to produce pictures of the inside of the body was realised in the late 1950s but it took until the 1970s for ultrasound scanners to be commonly used in hospitals.

CT scans (computerised tomography) became a reality in 1972. Although they have developed since then the principle is the same – CT scanners produce 3D images from a large series of 2D X-rays.

The MRI was first introduced in 1980. Magnetic resonance imaging scanners use a combination of magnetism and radio frequency waves to provide information about the body. Conventionally the scanners are tube shaped but an upright MRI is now available.
