Medical imaging refers to the techniques and processes used to create images of the human body (or parts thereof) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and physiology).

As a discipline and in its widest sense, it is part of biological imaging and incorporates radiology (in the wider sense), radiological sciences, endoscopy, (medical) thermography, medical photography and microscopy (e.g. for human pathological investigations).

Measurement and recording techniques which are not primarily designed to produce images, such as electroencephalography (EEG) and magnetoencephalography (MEG) and others, but which produce data susceptible to be represented as maps (i.e. containing positional information), can be seen as forms of medical imaging.

Imaging may also refer to:

• Digital imaging, creating digital images, generally by scanning, or through digital photography
• Medical imaging, creating images of the human body or parts of it, to diagnose or examine disease
• Radar imaging, or imaging radar, for obtaining an image of an object, not just its location and speed
• Chemical imaging, the simultaneous measurement of spectra and pictures
• Personal imaging, realtime sharing of personal experience through images
• Stereo imaging, an aspect of sound recording and reproduction concerning spatial locations of the performers
• Document imaging, replicating documents commonly used in business
