Outline of Final Research Achievements

Dense breast and younger age group's diseased rate are expensive more than Europe and America in Japan.Therefore it's being considered to add ultrasound exam to the breast cancer screening in Japan.But it was difficult to manage appropriately except for expert screener because quality control of breast ultrasonic equipment wasn't indicated clearly.
Therefore beginner's screeners have a possibility that they don't notice a breakdown of equipment and degradation.
In this study, We proposed the method which can estimate every facilities objectively using Phantom and digital Phantom. This study enabled objective quality control for breast ultrasonic equipment. Many screeners were simple and high reproducibility quality control became possible.
