Efforts focus on increasing examination sensitivity and specificity — both essential for efficient detection and patient dose reduction — beyond FFDM’s limits. Effective medical imaging must overcome two challenges:
DBT is designed to overcome the overlying structures problem.

The scan shown above depicts different structures or malignancies (biopsy cavity and micro-calcifications). These images of a freshly ablated breast, made using DBT enhanced with HPC detection, were acquired at ± 10° (21 angles) during a short scan. After comparing these with images from a conventional mammography flat panel, clinical radiologists delivered positive assessments of the DBT/HPC results. Overall, HPC is optimally suited for low-dose applications such as DBT. Its noise-free detection and high frame rate can help drastically reduce patient exposure to radiation.
