Digital Tomosynthesis

**Semantic type:** Diagnostic Procedure

**Definition:** An imaging technique in which multiple X-rays of an object are take from a discrete number of angles. These cross-sectional images are used to reconstruct 3-D images of the object being scanned. Tomosynthesis differs from computed tomography because the range of angles used is less than 360 degrees, as used in computed tomography.
