Abstract

Charge-coupled device (CCD) digital cameras have been used to expand the application area of conventional dosimeters to two-dimensional dose measurements. Although film dosimeters are normally read with scanners, CCD reading has several advantages over scanner reading: quick reading, interference filters, and no influence from the film orientation at the reading. Moreover, the lens and light source are changeable, which makes it possible to use a wide selection of dose ranges and spatial resolutions from microscopic to macroscopic.
