Variation in X-ray output and quality during a diagnostic exposure can be undesirable and may result in unnecessary dose to the patient. When significant build-up or decay periods are present errors will arise if factors obtained under steady-state c

Methods of measuring and ways of expressing patient dose in routine diagnostic radiography are briefly reviewed. Measurement of dose in units such as ergs or joules should be confined to instances when dose is measured in a specific structure: this w

A radiographic method is described for comparing the effective kilovoltage and inherent nitration of diagnostic X-ray machines. The apparatus consists of a modified Xray cassette covered by a sheet of lead perforated with two rows of holes; one row i

ICRU (1963) Handbook 89, states that conversion factors of X-ray image intensifiers should be measured using radiation having an HVL of 7±0·2 mm Al; full wave rectified or constant potential can be used. It is stated that this half value layer woul

The relative merits of tungsten and molybdenum targets for mammography have been the subject of much discussion. Therefore the spectra and outputs (at constant potential) from molybdenum and tungsten targets, interchangeable in the same tube, have be
