Features
· 3D-Matrix-Phantom for testing of thereconstruction accuracy in brachytherapy
· Made of PMMA
A solid phantom of very high precision designed to be used to check the different reconstruction techniques incorporated in brachytherapy treatment planning systems and in radiotherapy departments. These may include orthogonal X-rays, semi-orthogonal X-rays, stereo-shift methods, isocentric techniques utilizing C-arm X-ray equipment or a radiotherapy simulator. The Baltas Phantom can also be used for testing reconstruction algorithms and tools using CT based treatment planning procedures in modern brachytherapy. This can be realized within the framework of commissioning as well as constancy test procedures.
The phantom is cubic with 12 cm side length. It is built from 6 slabs of 2 cm PMMA thickness. Each of the slabs has a squared shaped surface of 12 cm side length. At each of the five interfaces, 5 marker spheres made by radiopaque material are inserted, resulting in a total of 25 spherical markers building a matrix.
