TABLE 4.
The minimum, maximum, mean, and standard deviation of the DVH D min, D max, and D mean reported from X1, Eclipse, and MIM for the same head‐and‐neck plan
| DVH D min, cGy | DVH D max, cGy | DVH D mean, cGy | ||||
|---|---|---|---|---|---|---|
| X1−Eclipse | X1−MIM | X1−Eclipse | X1−MIM | X1−Eclipse | X1−MIM | |
| Min (∆D) | −0.3 | 0.0 | −171.6 | −68.0 | −15.7 | −15.0 |
| Max (∆D) | 506.9 | 171.0 | 42.0 | 0.0 | 34.9 | 5.0 |
| Mean (∆D) | 31.3 | 13.5 | −34.8 | −23.4 | 6.7 | −0.8 |
| σ(∆D) | 122.6 | 41.0 | 55.3 | 26.5 | 16.0 | 5.5 |
Note ∆D represents the dose difference between two systems for a given DVH metric (i.e., D min, D max, or D mean).
