MRI Distortion Phantom for SRS.

 

CIRS Model 603A was designed for assessment of MR image distortion in Stereotactic Radiosurgery Planning.  It is also a useful tool for verifying image fusion and deformable image registration algorithms used in various treatment planning systems.  The tissue equivalent, anthropomorphic design provides the closest conditions to a clinical imaging scenario.  The phantom can be imaged using X-ray, Computed Tomography and Magnetic Resonance.  It images well with all MRI sequences tested to date, including T1 weighted, T2 weighted, 3D Time of Flight, MPRAGE and CISS.


Features

• Provides a realistic anthropomorphic scenario for CT and MR imaging

• Unique inter-cranial 3D grid design allows assessment of spatial distortion

• Special pads enable use with all fixation frames

• CT/MR markers facilitate positioning and image registration

The skull is manufactured from a plastic-based bone substitute, and the interstitial and surrounding soft tissues are made from a proprietary signal generating water-based polymer.  The entire phantom is encased in a clear plastic shell to protect gel from desiccation.  The phantom is supplied with specially designed pads that allow fixation with any stereotactic frame or mounting for end-to-end testing.  The phantom is also suitable for frameless SRS QA.

The entire inter-cranial portion of the skull volume is filled with an orthogonal 3D grid of 3 mm diameter rods spaced 15 mm apart.  Five extended axis-rods intersect at the reference origin of the grid.  The end of each extended axis is fitted with CT/MR markers allowing for accurate positioning with lasers and co-registration of CT and MR image sets.

The phantom includes right and left air voids, 3 mm in diameter by 17 mm long to simulate each ear canal for evaluation of potential distortions commonly found in clinical settings.
