Pencil Beam Technology
This technology projects an x-ray beam straight down  toward the patient.  The scan arm moves vertically over the patient as the pencil beam scans back and forth covering the width of the body.  The average scan time is 3 to 4 minutes with no radiation scatter and minimal dosage.

Fan Beam Technology

This technology uses an X-Ray beam that projects down in a fanned beam toward the patient.  The scan arm needs only a single vertical pass over the patient as the radiation is fanned across the width of the patient.  The average scan time is 30 to 90 seconds.  The radiation exposure is minimal, and many states require only that the operating tech wears a radiation detection badge.  The fan beam has some very minute radiation scatter.
