4.9 Technique Factors Settings and Adjustments
The factory settings in this chart are intended as a reference starting point only and are
based upon average preferences and use with the cone perpendicular to the image
receptor. Individual results may vary based upon a number of factors including image
density preferences, the various imaging sensors or available film speeds and brands,
patient size, practitioner techniques, and preferences.
Pediatric Considerations
Use of equipment and exposure settings designed for an average-sized adult can result in
excessive radiation exposure for a smaller patient, especially pediatric. Pediatric patients
may be more radio-sensitive than adults (i.e., the cancer risk per unit dose of ionizing
radiation is higher), and so unnecessary radiation exposure is of particular concern for
pediatric patients. Please use caution when configuring the KaVo NOMAD PRO 2 by
considering the patient’s age, size, body habitus, and clinical indication when verifying
exposure time settings.
