Indexing artefacts using a tertiary collimator and a method to avoid them.

Abstract

A tertiary, slotted grid collimator has been proposed as a method by which the spatial resolution of radiation fields shaped using a multileaf collimator (MLC) may be improved. The prototype device previously reported in the literature allowed each slot in the grid to be aligned with each pair of opposing leaves in the MLC. Irradiation through the… (More)
