Wide-angle breast tomosynthesis for optimal soft-tissue lesion visibility

PROMOTIONAL ARTICLE (PROMOTIVNI ČLANAK)

DBT involves multiple projections with a moving X-ray tube acquired across an arc, rather than one single central projection that’s acquired with FFDM. In contrast to computed tomography (CT), projections are obtained over a limited angular range. The angular range ( ) refers to the maximum angle (in degrees) that the X-ray tube moves from first to last projection and varies from 15° (narrow-angle) to 50° (wide-angle) in currently available clinical DBT systems. For an angular range of 50°, the X-ray tube moves from –25° to +25° or vice versa.
