Figure 6
Full single-scan modality to the skin. (a) Scan of the exposed radiochromic film; average dose profiles were evaluated in the horizontal and vertical ROIs indicated by the two rectangles in white. (b) Vertical profile (with indication of the FWHM) and (c) horizontal profile of the dose distribution. The vertical profile is bell-shaped with a FWHM of 3.38 mm while the horizontal profile (c) has a mean value of 5.44 mGy and a standard deviation of 1.8% around the mean value. These fluctuations are consistent with the radiochromic film dosimetry uncertainty. The insets show the position of the film on the surface of the cylindrical phantom.
