For the cos 6 (x) model, the mean volume of ITV allphase , ITV MIP , ITV T1 and ITV T2 was 38.01 ±1.00, 38.18 ±0.79, 30.52 ±0.72, and 35.88 ±1.16 cc, respectively. Similar to the sinusoidal motion results, ITV MIP resembled ITV GT the most among all structures. DSC of >0.87, JS of >0.77, HD of <8.68 mm and MDA of <1.13 mm were obtained when comparing ITV T1 and ITV T2 to ITV GT .
