THE CALCULATION OF DOSE FROM EXTERNAL PHOTON EXPOSURES USING REFERENCE HUMAN PHANTOMS AND MONTE CARLO METHODS - PART 4
This report considers the contribution from scattered radiation to the dose to organs and tissues which lie outside the useful therapy beams. The results presented are the product of Monte Carlo studies used to determine the tissue doses due to internal sputtering of the useful beams only. General cases are calculated in which central target volumes in the trunk are treated with 10 x 14 cm**2 and 14 x 14 cm**2 fields from 200 kV, 60-Co, 8 MV and 25 MV therapy equipment. Target volumes in the neck are considered to be treated with 5 x 5 cm**2 fields. Different treatment plans are calculated including rotational therapy. Also two specific cases are more fully analyzed, namely for ankylosing spondylitis and central abdomen malignant disease in the region of the head of the pancreas. The calculated organ doses are presented in tables as a percentage of the target volume dose.
