HIDXD, hand-held intraoral dental X-ray device.
Summary of select device specifications and X-ray beam quality for the five HIDXDs evaluated for stray radiation. Backscatter shields were in place for all devices. The source-to-skin distance for each device was 20 cm with the removable cones in place. A timer setting of 1.0 sec was used for the measured air kerma output for all devices. For each device, the timer setting is the only adjustable loading factor, thus differences in output for a given device are solely a result of changes to selected exposure time.
