Construction and Use of a Micro Resolution Phantom for Small Bore MRI

Despite their usefulness in quality assurance of high resolution small bore systems, resolution phantoms with feature sizes of 100um are not commercially available. This works describes the design, manufacture, and use of resolution phantoms with features in the 100um to 500um range. These can be easily designed using CAD software and manufactured using laser drilling techniques. This provides a custom cost effective solution for labs to perform testing on new or existing sequences.
