Dosimetry measurement tools for commissioning Enhanced Dynamic Wedge

Abstract 

Measurement of Enhanced Dynamic Wedge parameters requires that the dose at a measurement point be integrated during the entire exposure as the moving jaw closes to form the dose distribution. This major difference from static fields, where dose rate measurements can be made using a single moving probe, requires major modification in measurement techniques to use devices which can measure multiple points within the field simultaneously. Each of these new tools introduce unique problems in dose measurement, which must be understood prior to their use. This paper discusses these tools.
