Technical solutions to the problem of reducing patient dosage

One of the greatest challenges existing today in the field of radiology is the development of equipment and techniques which will permit an accurate diagnosis and at the same time assure that the patient is subjected to the minimum radiation theoretically needed to accomplish that diagnosis. It is the purpose of this paper to discuss the present knowledge concerning what constitutes the minimum dosage and the means available either now or in the not too distant future to produce a diagnostic image utilizing this minimum dosage.
