Figures

FIG. 1.

Calibration curve for the Molecular Dynamics PDSI Scanner, converting pixel values to optical density.

Image of FIG. 2.
FIG. 2.

The change in optical density response to each fraction of 0.5 and 1 Gy for five fractions. The HS film had no base dose applied.

Image of FIG. 3.
FIG. 3.

The change in optical density response to each fraction of 2 and 5 Gy for five fractions. The HS film had no base dose applied.

Image of FIG. 4.
FIG. 4.

The change in optical density response to each fraction of 0.5 and 1 Gy for five fractions. The HS film had a base dose of 5 Gy.

Image of FIG. 5.
FIG. 5.

The change in optical density response to each fraction of 2 and 5 Gy for five fractions. The HS film had a base dose of 5 Gy.

Image of FIG. 6.
FIG. 6.

The averaged optical density measurements of exposed HS film as a function of the total accumulated dose received by the film. This includes any base dose applied, but excludes any contribution from the scanner plate nor the diffusion filter. The error bars represent the standard deviation for the averaged optical density measurements.

Image of FIG. 7.
FIG. 7.

Plot of the average as a function of dose for the data illustrated in Fig. 6. Towards the low dose range, the slope nears a value of 0.04 and slowly decreases to 0.03 for the higher doses.

Tables

Generic image for table
TABLE I.

The difference in the optical density response to multiple fractions relative to a single fraction of the same cumulative dose for HS films with no base dose applied.

Generic image for table
TABLE II.

Comparison of optical density response of film to five fractions of 1 Gy vs a single fraction of 5 Gy for HS films exposed to different base doses.
