The apices, DEJ and bone detail are all clearly visible. **NOTE - this image is also unacceptable due to poor positioning recognized by the overlap of the contacts. While under-exposed images can be darkened using software, contrast may still be lacking. This can be recognized by the lack of contrast in the crowns of the teeth and the gray areas between the inter proximal regions and behind the molars, as well as the presence of the positioning tab in the inter proximal.

Timing or pulses depends on the patient's size and the area of the mouth to be x-rayed. Every X-Ray unit will behave differently depending on age, maintenance and usage. NOTE: If a particular x-ray generator is not listed here, see the kV and mA settings on the x-ray generator in use and compare them to those listed above. For more information, see FAQ 10187 - NOMAD Hand Held X-ray Machine Technique Factor Chart As a result, exposure time must be increased by roughly a factor of 3 to compensate for both this along with lower than preferred kV. **NOTE about ARIBEX NOMAD: Unit uses 2.5mA - around 1/3 of that seen on most wall mounted units.
