In this abstract, we are introducing an MRI compatible robot for needle placement for shoulder arthrography. Gold standard for this procedure is a two-stage procedure, i.e. an intra-articular contrast injection typically guided by fluoroscopy followed by an MRI. The current two-step workflow can result in prolonged sedation time when sedation is needed for younger patients, radiation exposure, and may increase cost due to the use of both the fluoroscopy and MRI suite. In this abstract new version of our MRI compatible robot is introduced. We aimed to reduce backlash and friction to increase the positioning accuracy of this new system.
