The principal reasons for this inefficiency are the low energy and short range of the -emissions and the barrier imposed by the protective coating of the X-ray film. and Wilcox, C.D.: Design and implementation of an image management system (IMACS) for dentomaxillofacial radiology. 3 H), adsorbed on TLC adsorbents, are inefficiently detected by direct exposure to X-ray films.

DEF film has been the workhorse in inertial confinement fusion (ICF) research and is used to record x-ray images and spectra.

This represents a relatively high dose to the patient. Molteni, R.: Direct digital dental x-ray imaging with Visualix/VIXA. Traditional screen-film systems use overall film density as an exposure indicator. This film basically was still photographic film. So, if a large patient is imaged on a digital detector through a thick body part, the X-ray technique must be adjusted upward to compensate for X-ray attenuation and to ensure a sufficient number of transmitted X-rays incident on the detector in order to achieve a desired exposure index value. and Kelly, M.S.: Flash Dent: an alternative charge-coupled device/scintillator-based direct digital intraoral radiographic system. and Welander, U.: Sens-A-Ray: a new system for direct digital intraoral radiography. and Matteson, S.R.: Direct digital radiography for the detection of periodontal bone lesion. and Duret, B.: The Radio Visio-Graphy (RVG): where reality surpasses radiological fiction-a hope that is becoming reality. The ease with which Biomax-MS can be used in place of DEF (same format film, same developing process, and comparable sensitivity) makes it a good replacement.Duret, F., Coste, B.C. The lower exposure results from thinner emulsion layers, designed for use with phosphor screens.
