Image of FIG. 1.
FIG. 1.

Measured (solid lines) and calculated (dashed lines) (a) profiles and (b) isodose distributions for a field used to treat prostate cancer with passively scattered protons at a depth of 19 cm. These isodose distributions and profiles are for a plane at the center of the SOBP. (c) 99% of the pixels met the 3% dose and 3 mm distance agreement criteria.

FIG. 2.

Measured (solid lines) and calculated (dashed lines) (a) profiles and (b) isodose distributions for a field used to treat lung cancer with passively scattered protons at a depth of 8.7 cm. These isodose distributions and profiles are for a plane at the center of the SOBP. (c) 100% of the pixels met the 3% dose and 3 mm distance agreement criteria.

Image of FIG. 3.
FIG. 3.

Measured (solid lines) and calculated (dashed lines) isodose distributions at different depths (0.14, 10.40, 19.40, and 23.40 cm) for a field used to treat prostate cancer with spot scanning proton beams. The nominal range and SOBP width for this field were 24.3 and 10.4 cm, respectively.

Image of FIG. 4.
FIG. 4.

Measured and calculated field profiles at different depths (0.14, 10.40, 19.40, and 23.40 cm) for a field used to treat prostate cancer with spot scanning proton beams. The nominal range and SOBP width for this patient field were 24.3 and 10.4 cm, respectively.
