FIG. 1.

Schematic of the three phantoms used in the dose-depth study. Phantom SSSSSSS is a homogeneous soft-tissue phantom, where each disc is composed of the tissue-equivalent material STES-NB. Phantoms SSBBSSS and SBLLBSS are heterogeneous phantoms consisting of combinations of soft and bone tissue, and soft, bone, and lung tissue-equivalent materials, respectively.

FIG. 2.

Comparison of measured and simulated tissue absorbed dose with depth within the homogenous soft-tissue phantom. Two orientations of the MOSFET dosimeters were considered: (A) epoxy bubble facing the x-ray beam, and (B) flat side of the dosimeter facing the x-ray beam.

Comparison of measured and simulated tissue absorbed dose with depth within the heterogeneous soft-tissue and bone-tissue phantom. Two orientations of the MOSFET dosimeters were considered: (A) Epoxy bubble facing the x-ray beam, and (B) flat side of the dosimeter facing the x-ray beam.

Comparison of measured and simulated tissue absorbed dose with depth within the heterogeneous soft-tissue bone-tissue, and lung-tissue phantom. Two orientations of the MOSFET dosimeters were considered: (A) epoxy bubble facing the x-ray beam, and (B) flat side of the dosimeter facing the x-ray beam.
