MAGPHAN® RT: An integrated MR QA system for radiotherapy

The Magphan® RT has been designed to meet the specific needs  MR QA in radiotherapy planning and guidance.  Distortion measurements for MRI in radiotherapy require a large field of view to encompass the range of torso sizes encountered in clinical practice. The Magphan RT’s modular design provides 2 different sizes. The large body configuration can measure distortion over a volume of 35 x 27 x 21cm and the super size configuration measures over a volume of 35 x 39 x 21 cm. The Magphan RT analysis system allows multiple image sets to be stitched together thus allowing a larger superior- inferior dimension to be achieved through table indexing.

With the large measurement volumes required for RT applications weight can become an issue. In order to make the phantom manageable for a single person without special handling devices we created a modular design with self contained sections that fit together precisely. For the large body configuration there are two sections (top and bottom) . The super size configuration includes a center module to increase volume in the the AP direction. Each module is light enough to be handle by a single person.

The modular design not only allows for easy handling of the phantom but also facilitates future system expansion with additional measurement modules.

CATPHAN® CT PHANTOMS

The Phantom Laboratory and physicist David Goodenough, Ph.D., have worked together to develop the Catphan® Phantom line. Catphan® designs are based on four decades of scientific research and direct field experience in the evaluation of CT scanning equipment.

The Catphan® system has evolved with advances in CT technology to ensure that you can measure the full capabilities of today's advanced scanners.

TOMOPHAN® DBT IMAGE QUALITY PHANTOM

If you have not worked extensively with digital breast tomosynthesis (DBT) imaging, you may not be fully aware how different it is from conventional mammography and CT. The Tomophan® phantom has been designed to provide a complete characterization of this unique imaging system through objective measurements of key performance criteria.
