Several recent reports have described methods for calculating enhanced dynamic wedge factors (EDWFs). Many of these reports use the monitor-unit (MU) fraction method to predict EDWFs as a function of field size. Although simple in approach, MU fraction methods do not produce accurate EDWFs in large or asymmetric fields. A recently described technique, based on the MU fraction method works well ...
A technique for calculating the electric field in interference coatings is described. The used to find areas coating structure with minima. Thin absorbing metal films are introduced into these during design. results of transmission spectra narrow-band filters presented. It shown that such metal-dielectric thin-film structures block radiation long-wavelength region spectrum. Keywords: electromag...
BACKGROUND Central to the design of a randomised controlled trial is the calculation of the number of participants needed. This is typically achieved by specifying a target difference and calculating the corresponding sample size, which provides reassurance that the trial will have the required statistical power (at the planned statistical significance level) to identify whether a difference of...
