One of the breast cancer screening and diagnosis methods is MRI-guided breast biopsy. Current techniques have limitations in accuracy and efficiency, which may cause lesions to be missed.

In this research, two separate innovations are investigated and reported. The first innovation is to improve the breast fixation mechanism by using so-called coffee grippers, which can secure the breast in place. The other innovation is to make use of a robotic biopsy system for needle alignment and insertion, which results in a more accurate biopsy needle insertion and also speeds up the biopsy procedure.

Both innovations were investigated with experimental setups. It turns out that the innovative breast fixation
mechanism certainly has potential, but that it is difficult to be practically effective considering the large variations in breast size and other factors. On the other hand, the robotic biopsy system proved to be effective and accurate in semi-automatic needle positioning and alignment. This way, more accurate biopsies are possible resulting in better cancer diagnosis.
