The Alderson Radiation Therapy Phantom

The Alderson Radiation Therapy phantom (ART) and its earlier version, the Alderson RANDO phantom, have been in use for over 30 years. The ART has been refined and improved in both design and materials. These phantoms are indispensable quality-assurance tools; about 10,000 are in use all over the world. They provide integrated tests of the entire chain of treatment planning and delivery.

ART phantoms are molded of tissue-equivalent material; they are designed within highly sophisticated technological constraints and follow ICRU-44 standards. They are also designed for accuracy and ease of use. a large female.

The Treatment Brassiere

Data on increased skin dose due to the ipsilateral cup were submitted to the FDA. These data provided a comparison of skin dose increased by the Treatment Brassiere with the increase found for various thermoplastic positioning devices on the market. The skin dose due to the cup material (0.50 mm thick for small cups to about 0.63 mm thick for very large cups) was found to be substantially less than for other positioning devices. The FDA has issued a 510 (k) Marketing Clearance for the Treatment Brassiere.

Phantoms For Linac Radiosurgery And The Gamma Knife

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.

Dynamic Anatomical Respiring Humanoid Phantom

The dynamic breathing phantom (TBP) is based on the Alderson Radiation Therapy (ART) phantom.

The soft tissue materials in the breathing phantom are elasticized versions of the same materials refined for the ART phantom. Rigid bones are incorporated and move under the respiring motion in the phantom. The elastic lungs have realistic respiratory density.
