An algorithm is:

An algorithm is:

• A. A mathematical hypothesis used in imaging
• B. A mathematical formula used to reconstruct the image in digital imaging
• C. An advanced imaging procedure
• D. The mathematical basis for film-screen imaging

Answer: (B)

An algorithm is a defined set of steps, usually expressed as a mathematical procedure, that turns raw data into a final image. In digital imaging, reconstruction relies on such a method to convert detector signals into a viewable image. This distinguishes it from the imaging procedure itself (which describes how data are acquired), from the physics underpinning film-screen imaging, or from an abstract hypothesis. For example, reconstruction formulas like those used in filtered back projection or iterative techniques are algorithms that mathematically reconstruct the image from the collected data.
