What Is Diagnostic Medical Imaging

The technology to extract clinical useful information in the format of images.

The Imaging involves physics, engineering, computer sciences, and biology.

Development of Imaging Methods

Two major advances from technologies developed during World War II (1 & 2)

(1) Nuclear Medicine from the availability of radioactive materials from nuclear reactors during late 1940s

(2) Diagnostic ultrasound evolved from the develop- ment of SONAR (sound navigation and ranging);

(3) Introduction of computed tomography (CT) in the early 1970s and magnetic resonance imaging (MRI) in the 1980s.
