| Outline of Final Research Achievements |
Recently, DBT has been developed and has been introduced in a clinical field.
This device is expected as the new imaging modality that can contribute to the improvement of diagnostic accuracy in the breast cancer because it can produce slice images and 3D images.In this research, we evaluated and confirmed that DBT had higher diagnostic value compared to conventional 2D. In addition, we developed new image processing parameters of DBT and compared to the current DBT images. As a results, we also confirmed that the new image processing parameters showed higher diagnostic values and higher depiction values compared to conventional DBT images using current image processing parameters.
