title: Compact foreign-made dental x-ray generators: an evaluation of their acceptability for effective dental radiography. II. Image characteristics and observer performance.
abstract: Imported generators, while inexpensive and compact, feature fixed peak kilovoltage and fixed milliamperage levels. These generators, because of the relative inflexibility of their operating characteristics, cannot be modified to produce radiographic image characteristics of equal diagnostic value to the domestic generators without compromises which are unacceptable.
