Data are presented to allow the photon beam quality specifier being used in the new AAPM TG-51 protocol, %dd(10)x, to be extracted from depth-dose data measured with a 1 mm lead foil either 50 cm or 30 cm from the

Two dosimetry protocols based on absorbed dose to water have recently been implemented: TG-51 and TRS-398. These protocols use different beam-quality indices: %dd(10)x and TPR20,10. The effect of electron contamination in measurements of %dd(10)x has been proposed as a disadvantage

It is useful to utilise a computed radiography system with a combination of storage phosphor plates and therapy cassettes for portal images. However, the therapy cassette has some disadvantages. The objective of the present study was to determine whether the
This study investigates a possible cause of reported significant dose discrepancies between Monte Carlo calculations and measurements in the buildup region for high-energy photon beams in large fields. A proposed hypothesis was that the discrepancy was caused by a source

The purpose of this study was to determine if condylar morphology can be accurately depicted on the panoramic radiograph and if variations in condylar anatomy affect the radiographic appearance of the condyle. The shape and angulation of the condyle were
