Article Snippet: Moreover, the commercially available StereoPHAN phantom in combination with the SRS mapCHECK 2D diode array (both produced by Sun Nuclear Corp., Melbourne, FL) were used for plan verification of a challenging VMAT‐SRS case and results are compared with TPS‐calculated dose distributions obtained after changing the clinically used leaf offset parameter.
