- Comparison of x-radiation doses between conventional and rare earth panoramic radiographic techniques.
Comparison of x-radiation doses between conventional and rare earth panoramic radiographic techniques.
The radiation dose to radiobiologically critical organs at various anatomic sites in a phantom was compared with the use of rare earth screen/film combinations and calcium tungstate screen/film combinations. Rare earth screens and films produced a reduction in dose up to 40% to 50% depending on the anatomic site.
