CCEFP update: Additive manufacturing creates MRI-compatible pneumatic actuators

For some 2.2 million patients in the United States suffering from a treatment-resistant neurological disease, needle-based interventions have the potential to provide a minimally-invasive surgical cure. For safety and accuracy, these procedures require visualization of the needle relative to the target and adjacent untreated tissue. This visualization is typically done using magnetic resonance imaging (MRI). Because the magnet bore of the MRI machine closely surrounds the patient (the typical bore diameter is 60 cm), a compact robot is essentially required to access the patient and perform the surgery.
