Abstract
The quality assurance phantom for intensity-modulated radiation therapy is adapted for use with multiple dosimetric devices, such as ion chambers, MOSFET's, radiochromatic film, and TLDs. The phantom includes a base to which a static block is fixed. A dynamic block is mounted on the base and is adjustably spaced from the static block. A plurality of film dividers are sandwiched between the blocks. After film is inserted between the film dividers, the blocks are clamped together. The static and dynamic blocks include a plurality of cavities for receiving various dosimeters. The dosimeters are interchangeable within the cavities, so as to enhance the versatility of the phantom.
