Lumbar Punctures (LP) are generally guided by palpation only without visualization of the internal anatomy, leading to repeat attempts and/or avoidance in difficult cases. Image guidance with US and X-ray is possible, but US has poor depth and CSF contrast and radiation from X-ray complicates Point of Care (POC) use. We present a magnet design for a POC MR guided LP device that will couple to a mechanical track for needle insertion. The single-sided magnet is an NdFeB array and achieves a 40mT field and ~50mT/m built-in gradient in the ROI. Simulations of the magnet and imaging procedure are presented.
