Square Rabbit™ White Rabbit™ Phantoms |
|
The Square Rabbit QA Phantom consists of five square 30 x 30 cm slabs - (2) 5 cm-thick slabs, (2) 4 cm-thick slabs, and (1) 2 cm-thick slab. The outside slabs have radius cut edges.
The slabs can be drilled to support an ion chamber. In addition, two film fiducials in the 2 cm slab allow for easy marking of film for absolute registration in the ProCheck™ IMRT QA software package.
Ultra-high molecular weight polyethylene (UHMW) is used to construct the Square Rabbit QA Phantom. UHMW has a density of 0.928 - 0.941 g/cc (depending on the source of reference). The phantom has 20 cm in diameter and 30 cm in length.

Square Rabbit IMRT QA Phantom, MT-NW-500-820 |
The White Rabbit IMRT QA Phantom consists of seven stacked disks forming a cylindrical phantom. The disks are 28 cm in diameter and have a central hole in four of the disks to accept an ion chamber. A holder lets the cylinder lay on its side for irradiation simulating the patient position. A second hole near the periphery is used to measure tangential treatment fields. Solid disks can be removed from the phantom and used to irradiate planar dose films, or a film can be put in the phantom for combination field exposures. Positioning the phantom accordingly can produce films in coronal, sagittal, or other planes.
Ultra-high molecular weight polyethylene (UHMW) was used to construct the Square Rabbit QA Phantom. UHMW has a density of 0.928 - 0.941 g/cc (depending on the source of reference). The phantom measures 28 cm in diameter and 25.9 cm in length.
