A Study on the Compression Paddle Materials to Reduce Exposure during Mammography

摘要

During mammography, it is necessary to press the breast with a compression paddle to increase the concentration and contrast of images and to obtain images with high diagnostic value by using reduced exposure dose. This study is related with the compression paddle that is used for the evaluation of materials in terms of the values of radiolucency, and each pixel in existing polycarbonate, plastic series was compared by using Image J. The radiolucency dose of compression paddle material was measured as 8.552m ?У after removing the compression paddle; and the value for the materials was 6.308 m?У for PC, 5.766 m ?У for PET, 6.488 m ?У for Nylon-6, 7.067 m ?У for LLDPE, 7.174 m ?У for LDPE, 7.147 m ?У for Block-PP, 7.207 m ?У for Homo-PP, 7.140 m ?У for HDPE, 7.181 m ?У for CO-PP, and 5.550 m ?У for Acetal. The pixel value of the dose that passed each material was 975.795 after removing compression paddle without radiation attenuation by using Image J; and the pixel value for each material was 829.104 for PC, 794.679 for PET, 844.857 for Nylon-6, 891.851 for LLDPE, 888.347 for LDPE, 889.081 for Block-PP, 892.62 for Homo-PP, 887.416 for HDPE, 890.228 for CO-PP, and 780.324 for Acetal.
