Product Description

For Evaluation of Treatment Accuracy  

The CIRS Radiosurgery Head Phantom was designed to improve the accuracy of treatment plan verification in radiosurgery.  It allows for 3D dose verification in a large cranial volume.  

The Phantom is manufactured from proprietary epoxy materials and contains brain, bone spinal cord, vertebral disks and soft tissue.  Linear attenuations of the tissues are within 1% of actual attenuations from 50 keV to 25 MeV.  

The standard 6.4 x 6.4 x 6.4 cm film stack contains 13 levels of X-ray or Gafchromic® film to evaluate accuracy of 3D dose distribution. It can be interchanged with an equivalent gel dosimetry cassette or TLD holder.  Two brain-equivalent spacers allow the user to locate the cassette in one of four different positions.
