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.
