Features
• Check 2D dose distributions (3D distributions optional)
• Point dose measurements in multiple planes
• Calibrate film with ion chamber
• Quickly verify individual treatment plans
• Correlate CTU to electron density
The Homogeneous Phantom allows quick checks of patient plans using one 10”x12” Ready Pack™ film. It has fine interchangeable rod locations and one set of CT film fiducial markers. The Homogeneous Phantom is elliptical in shape and properly represents human anatomy in size and proportion. It measures 30 cm long x 30 cm wide x 20 cm thick (PA).
Water equivalent interchangeable rod inserts accommodate ionization chambers allowing for point dose measurements in multiple planes within the phantom. The phantom also supports radiographic or GafChromic® film at mid-plane in the phantom for analysis of dose distributions.
Handling, assembly and proper orientation of the phantom is made easy with the use of a unique alignment base and holding device. The surfaces of the phantom are etched for ease of laser alignment, and CT markers ensure accurate film to plan registration.
