Patient Dose

Measuring the mean glandular dose to the standard breast has for many years been the main means of assessing the doses from mammographic systems. Although this is a valuable and simple approach to dose measurement it provides limited information on the doses received by individual women. Consequently the periodic measurement of doses for samples of women undergoing mammographic examinations is recommended. The NHSBSP has published software (written by NCCPM) to calculate and store the results of such dose surveys.

The use of this software helps standardise dose measurements and simplify procedures for national reviews of radiation doses in the NHS Breast Screening Programme. The software incorporates the changes in the UK dosimetry protocol outlined by Dance et al (Phys.Med.Biol,45:3225-3240,2000).

The software can be downloaded here. This version includes HVLs up to 0.8.

The software's manual can be obtained here.
