The CIRS Model 002H9K offers a complete QA solution from CT imaging to dose verification. With the H9K, choose any point dose location 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. The center cylinder from the phantom body can be removed to simulate head and neck set-ups.
The phantom is constructed of proprietary tissue equivalent epoxy materials. Linear attenuations of the simulated tissues are within 1 percent of actual attenuation for bone and water from 50 keV to 25 MeV. These materials reportedly eliminate the need for correction factors, thus improving accuracy and saving time. The phantom simulates the patient through the entire process from CT data acquisition and planning to delivery and dose verification.
