Our studies have compared the “effective tissue–air ratio (TAR) method” (ICRU Report No. 24), “equivalent TAR method,” and the “generalized Batho method” (currently used by the TP‐11 computer treatment planning system) with measured results for different energy photon beams using two lung inhomogeneities to simulate a lateral chest field. Significant differences on the order of 3%–15% were found when comparing these various methods with measured values.
