4DCT
4DCT (pronounced "four-dee-see-tee"), also known as Four-Dimensional Computed Tomography, is a medical imaging technique that combines multiple CT scans to create a time-resolved, or "four-dimensional," image of a moving object, such as the lungs or heart.
Pronunciation
- IPA: /fɔːr.diː.siː.tiː/
Etymology
The term "4DCT" is derived from the words "four-dimensional" and "computed tomography." "Four-dimensional" refers to the three spatial dimensions (length, width, and height) plus time, while "computed tomography" is a type of imaging technique that uses computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object.
