|MRI Distortion Phantom for SRS.|
For Rapid Assessment of Image Displacement in Treatment Planning Systems|
The CIRS 3D Anthropomorphic Skull Phantom is made from materials that can be imaged using X-ray, Computed Tomography and Magnetic Resonance Imaging. It images well with all MRI sequences tested to date, including T1 weighted, T2 weighted, 3D Time of Flight, MPRAGE and CISS sequences.
The skull is manufactured from a plastic-based tissue substitute, and the interstitial and surrounding soft tissues are made from a proprietary water-based polymer. The entire phantom is encased in a clear vacuum-formed plastic shell to protect the gel from desiccation.
The entire cranial portion of the skull volume is filled with a orthagonal 3D grid of 3mm diameter rods spaced 1.5 cm
|apart. Five extended axis-rods intersect at the reference origin of the grid. The end of each extended axis is fitted
with CT and MR markers allowing for accurate alignment with laser-light as well as image co-registration.
The phantom includes a 6.35 mm diameter acrylic rod with an air void of 3 mm diameter and 17 mm long in each ear canal.
