Background: The objective of this paper is to illustrate the effect of a gap of 5 mm, an overlap of 5 mm and a perfect match on the dose distribution across the junction of tangential breast fields and adjacent supraclavicular and axillary fields.Materials and methods: For this purpose film dosimetry was applied to measure relative dose distributions in two sagittal planes in an anthropomorphic breast...
Aim: To use portal images acquired in routine circumstances for assessment of midplane dose variations in the patient.Material and methods: Optical density readings are performed on routinely acquired Verification films of breast and ear-nose-throat (ENT) cancer patients and these readings are converted into relative doses with the sensitometric curve. (1) The impact of redistribution is evaluated...
