We present an augmented reality system that integrates needle shape sensing technology and a visual tracking system to enable a more effective visualization of preoperative MR images during MR-guided needle biopsy procedure. It allows physicians to view 3D MR images of targets within the patient fused onto the patient anatomy as well as a virtual biopsy needle registered to the real needle. This provides what-you-see-is-what-you-get interaction even after the needle is inserted into the opaque body and can improve on current MR-guided needle biopsy by providing a faster tracking, and by enabling real-time interactive procedures based on pre-acquired scans, thus avoiding costly MRI scans.
