CIRS IMRT Head & Torso Freepoint Phantom.

The Freepoint Phantom allows any point dose location to be selected  within a circular area with diameter of 11.2 cm by simply adjusting the two rotating cylinders.  Lung and bone equivalent rods can be positioned at any location within the circular area for assessment of heterogeneity correction.  Remove the center cylinder from the phantom body to simulate head and neck set-ups.

•  Ionization chambers, TLD, MOSFET and Diodes easily positioned using interchangeable rods.

•  Choose any point dose location by rotating the cylinders.

•  Use radiographic Ready Pack® film or Gafchromic® film.

•  Close placement of detectors to film improves film calibration.

•  CT - film markers ensure accurate film to plan registration.

•  Surfaces are etched with indices for precise alignment.

•  Configure with or without heterogeneities.
