title: [Direct radiographic magnification and radiation exposure].
abstract: The advantage of microfocal X-ray units is the production of high-resolution magnification radiographs. Up to a magnification of x 4 the exposure equals that of a conventional radiograph. Some filter materials have been tested, aluminium filtration was found to be the best choice.
