Evolution of Diagnostic Imaging Technology

Historical Perspective

The history of modern medical imaging technology spans many decades. X-rays and ultrasound emerged in the early 20th century, providing the first non-invasive glimpses into the human body. Beginning the in 1950s, significant advances were made with technologies like CT scanning and MRI. Over many years these complex technologies gradually developed into essential mainstays of clinical diagnostic imaging.

The first commercial CT scanner called the EMI Mark 1 was invented in 1972 by Godfrey Hounsfield. It captured images by rotating X-ray beams and detectors around the body. Through the 1970s and 1980s, CT scanners evolved from head-only imaging to covering full bodies with ever greater resolutions.

Meanwhile, MRI technology traces back to the discovery of nuclear magnetic resonance in the 1940s. Through the 1970s, techniques were developed to apply NMR for medical purposes. In 1977, Raymond Damadian built the first machine specifically designed for NMR scanning of the human body called the Indomitable. The first true commercial MRI was released in 1983.

These breakthroughs sparked continuous refinements to CT and MRI technologies that persist today. Modern CT scanners and MRI machines bear little semblance to their bulky predecessors, having benefited enormously from the electronics and computer revolutions.
