Mechanisms of controlling colour

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The aim of this study is to explore and develop methods of controlling colour while overcoming many of the inherent problems in the processing. Because to the enormous variety of paper available, testing for printing was narrowed to primarily 100% cotton papers. The negative was critical in realising the full potential of the salt prints tonal range. The film tested was limited by availability in the Australian market. The research into various films to create digital output negatives proved to be complex and time consuming.
