Dr. Bradford Wood demonstrates remote-controlled robotic needle insertion to a predetermined target.
During medical GPS (fusion imaging)-guided tumor ablation, pre-procedural PET, MRI and/or CT scan are fused (registered) to ultrasound for real-time multi-modality feedback on needle position during treatment.

Interventional radiology's stereotactic frame is attached to a CT-gantry with hanging tools, including a robot; medical GPS (electromagnetic tracking or fusion image guidance); and high-intensity, focused-ultrasound (noninvasive tissue destruction or drug delivery).
The "operating room of the future" includes rotational angiography in the foreground and CT-based tools in the background.
Dr. Bradford Wood is chief of the Center for Interventional Oncology.
From left to right, in foreground, are high-intensity, focused ultrasound; medical GPS; and a robot (for automated, point-and-click needle placement).
Dr. Bradford Wood uses a radiofrequency generator for thermal ablation of tumors (lower right) and a magnetic field generator (the "satellite" of medical GPS, on left).
Shown is the procedure space for minimally invasive, image-guided therapy, in which imaging feedback during procedures may improve treatments.
The working space of the low-field magnetic generator is 500mm cubed. This device glues multiple imaging modalities together.
Drs. Bradford Wood (left) and Peter Pinto complete a pre-procedural selection of MRI targets.
An engineer, part of an academic-industry-government cooperative research and development agreement, tunes software for a procedure.
Physicians use multi-modality imaging feedback during the prostate fusion biopsy to precisely place needles to predetermined targets.
Multi-disciplinary collaborations require close communication and lack of disciplinary barriers, leveraging the unique translational environment of the NIH Intramural Research Program. Dr. Peter Pinto (left) is a surgical liaison for the Center for Interventional Oncology.
Close collaborations enable new perspectives on procedural medicine.
An ultrasound transducer with electromagnetically tracked sensors images the prostate during procedure with real-time feedback from pre-procedural imaging (MRI), which has been glued (registered) to the patient and to the ultrasound.
In 1955, open heart surgery was performed at the NIH Clinical Center using an ice bath and heart bypass.
Today percutaneous (with small incisions) devices are used to deliver high-dose regional chemotherapy to where it is needed. The chemotherapy is filtered outside the body on bypass before clean blood is returned to the patient, which limits systemic side effects and maximizes drug delivery to the disease location.
