Design of a needle control device for MRI-guided interventions

This graduation project consists of the design of the needle control device for MRI-guided interventions. It is an apparatus that grabs and steers a flexible needle remotely, so it could be used in an MRI while the physician controls the needle based on the scans. In this way, the physician has a clear sight of the position of the needle and the...

PneuScape: Towards High Resolution MR Safe Actuation

A future version of the DEMCON Needle Placement System (NPS) for use in the Magnetic Resonance Imaging (MRI) scanner requires accurate and small actuators that are MR (Magnetic Resonance) safe; actuators that can safely operate without interfering with the MR environment. The pneumatic stepper motor was chosen for actuation of the aiming...
