The accurate detection of cancers in screening mammograms requires the highest possible performance of the radiographic equipment, since such features are at the limit of detection. At present image quality is assessed by visual inspection of a radiograph of a test object, usually by a scoring system based on the visibility of features. This assessment is clearly subjective and open to inconsistencies over time and between observers.
A project carried out in collaboration with the National Coordinating Centre for the Physics of Mammography (based at St Lukes Hospital, Guildford) has investigated the potential application of computer methods to arrive at a reliable and objective means of scoring test object radiographs and therefore quantifying the performance of the screening equipment. The longer term aim of the work is to develop a standardised methodology which may be applied routinely by all UK Screening centres to in-service units and also units under commission or development. All of these factors contribute towards ensuring a service of the highest quality to women undergoing the screening provided by the NHS BSP.
This work was funded by the South West Thames Regional Health Authority, and undertaken in collaboration with St. Lukes Hospital, Guildford.
