Description
Summary:The study of the breast using mammography commenced at the major cancer centre in the late 1960s. Clinically useful images were first obtained using a Xerox system in the early 1970s. The development of quality assurance phantoms since this time is described, also research into the evaluation of breast dose and optimisation of the imaging chain. Physical and biological phantoms were used to evaluate available imaging configurations, and examples of the parameters investigated - target material, choice of image receptor - are given. A number of Monte Carlo programmes have been developed to quantify image quality parameters and patient dose. They have been used to optimise available imaging configurations for a wide range of breast thicknesses and radiographic parameters. Examples of studies into dose reduction by the addition of filtration choice of kVp, and the use of grids are given.
