The Impact of DBT Angular Range (15° vs. 50°)

DBT acquires and combines breast images from multiple angles to create a kind of a 3D data volume of the entire breast. This is displayed in slices parallel to the detector surface and reduces the impact of overlapping breast tissue. Various commercially available systems use acquisition angles between 15 and 50 degrees. At 50 degrees, Siemens Healthineers’ Digital Breast Tomosynthesis (DBT) offers the widest angular range, resulting in higher depth resolution and better visibility of low-contrast objects.1,2

The effect of the angular range in digital breast tomosynthesis is presented in both a physics study and a discussion of clinical experience.3
