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.
