Technical note: The effect of the 4‐mm‐collimator output factor on gamma knife dose distributions

We present results of investigations of the clinical significance of variations in the value of the 4‐mm‐collimator output factor, [Formula: see text]. Changes in treatment volume, dose‐volume histograms (DVHs), and isodose distributions were studied, by varying [Formula: see text] up to 20%. The va...

description We present results of investigations of the clinical significance of variations in the value of the 4‐mm‐collimator output factor, [Formula: see text]. Changes in treatment volume, dose‐volume histograms (DVHs), and isodose distributions were studied, by varying [Formula: see text] up to 20%. The variations were performed on a sample of clinical patient treatment plans for which the 4 mm collimator was used. Although smaller effects are noted for the prescription isodose line, greater dosimetric changes occur for higher dose regions within the target. PACS number(s): 87.53.–j, 87.52.–g
