Spherical Phantom to Check Mechanical & Dosimetric Parameters of Treatment Units
When the center of the sphere is used as the target for testing the treatment unit, it must indicate the relationship between the point of maximum dose and the target. These should closely coincide for an accurate system.
A three-dimensional dosimetry cylinder at the center of the sphere measures both the deviation of the maximum dose from the target and the gradient of the dose along the three orthogonal axes of the sphere.
Features and Benefits
- Homogenous dry water phantom with precise spherical shape – 16 cm diameter
- Displacement of maximum dose from center of sphere shows degree of accuracy and stability of the system
- Checks the dose-calculation algorithm for a homogenous sphere
- If both the sphere and head are purchased, only one dosimetric cylinder is needed
- This is a dry-water cone, which fits precisely in a recess in the sphere.
- It accepts the dosimetric cylinder (TLD or film).
- It houses the dosimetric cylinder at the center of the sphere.
