Digital breast tomosynthesis (DBT) value in breast mass detection

Digital Breast Tomosynthesis (DBT)

DBT is a three-dimensional (3D) breast imaging technology that uses a rotating X-ray source to acquire multiple image slices at several angles. The X-ray source rotates around the breast in an arc. Serial exposures are taken every few degrees in the arc rotation. These images are then reconstituted by software to produce a 3Dimage of the breast, similar to CAT scanning. It has been suggested th...

Optimization of Digital Breast Tomosynthesis (DBT) for Breast Cancer Diagnosis

Recent papers have reported the usefulness of DBT as the latest diagnostic modality for breast cancer [1]-[6]. In this chapter, the author describes clinical evaluation of the usefulness regarding DBT with reference to other diagnostic modalities such as Full Field Digital Mammography (FFDM), contrast-enhanced (CE) MRI, contrast-enhanced (CE) CT, and ultrasound (US) in accordance with prelimina...

Adaptive Diffusion Regularization for Enhancement of Microcalcifications in Digital Breast Tomosynthesis (DBT) Reconstruction

Digital breast tomosynthesis (DBT) has been shown to increase mass detection. Detection of microcalcifications in DBT is challenging because of the small, subtle signals to be searched in the large breast volume and the noise in the reconstructed volume. We developed an adaptive diffusion (AD) regularization method that can differentially regularize noise and potential signal regions during rec...
