What is it indicated for?

The Somatom Plus 4 with Volume Zoom package is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from either the same axial plane taken at different angels or spiral planes* taken at different angles.

(*spiral planes: the axial planes resulted from the continuous rotation of detectors and x-ray tube, and the simultaneous translation of the patient.)

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
