Catphan® 700

The Catphan® 700 Phantom has been designed to address the image performance measurement requirements for state of the art CT volume scanners.

The phantom retains many of the tests and features offered in the other Catphan® models including the CTP515 low contrast test module and integrated case mounting system. Other test objects have been refined in this development including the addition of higher resolution test patterns in the new CTP714 1 to 30 line pair per centimeter test module, the addition of smaller acrylic spheres to our low contrast sphere array contained in the CTP682 sensitometry slice geometry module, and additional bone and lung samples to assist customers using their CT images for radiation therapy treatment planning.

Along with numerous modifications, the phantom also contains the new CTP721 wave insert for measuring slice geometry and resolution across the scan area. Also, in order to address possible variables due to test pattern orientation with the scanners x and y axis, the phantom has a new rotation mount. This enables the mounted phantom to be rotated 360° with alignment detents at 45° intervals to study possible angular position-dependent results.

Catphan® 700 design and construction

Test precision, durability, and efficient operation are the key design. The Catphan® 700 continues to utilize the modular concept developed with the original Catphan® phantom. The three solid cast test modules are mounted inside the phantom’s housing. The wave insert and complementary MTF bead blocks press into pockets on the uniformity body that attaches to the module housing. The new rotating mount is connected to the module housing. Using the new mount, the phantom can be quickly cantilevered off the end of the table and rotated into various angular positions to allow for artifact free scanning.

While most customers will never choose to disassemble their phantom, special care was taken in the development of the Catphan® to enable disassembly for potential upgrades or modifications. To prevent hardware artifacts, no metal hardware is used to connect the wave uniformity section to the module housing or between the housing and the mount.

Catphan® 500, 600, are designed for comprehensive evaluation of axial, spiral, multislice, conebeam, and volume CT scanners.

Catphan® Phantoms are internationally recognized for measuring the MAXIMUM obtainable performance of axial, spiral and multislice CT scanners. The Catphan® modular design allows test modules to be interchanged.

The Catphan® Phantoms are constructed from modules that fit snugly into a durable 20cm housing. All Catphan® modules are made from solid-cast materials, solid-cast construction eliminates material absorption of water, freezing and leaks associated with water bath phantoms, as well as, problems related to varied water sources.

Tests apply to all Catphan® models: Note: These products work well with AutoQA Plus CT Catphan® Software and also Catphan® QA Automated Computer Analysis Program from Image Owl, Inc.

The Phantom Laboratory and physicist, David Goodenough, Ph.D., have worked together to develop the Catphan® Phantoms.

The new Catphan® designs are based on three decades of scientific research and direct field experience in the evaluation of medical imaging equipment. These phantoms are used to complete comprehensive performance evaluations of axial, spiral and multislice CT scanners and to implement quality assurance programs.

As your testing needs change and new modules are developed you can upgrade test modules that are compatible with your Catphan® system. Additionally, the Catphan® system is ideal for traveling physicists and engineers who conduct comprehensive evaluations of CT scanners at multiple locations as they are easily transportable and no draining is required between uses.

Catphan® QA Automated Computer Analysis Program from Image Owl, Inc.

To assist Catphan® customers, The Phantom Laboratory has worked with Image Owl, Inc. to develop a web-based automated service for analysis of Catphan® phantom images with the versatility of Internet access. Catphan® 500, 503, 504, 600, and 700 models are supported.

The Phantom Laboratory sponsors a free version of the service available for Catphan® customers. Customers scan their phantom and upload a DICOM image to the web-based server where the test module is identified and results reported by the automated system. The report is available to download or print for the customer's records.

Image Owl offers additional advanced tools and services with a yearly subscription, including multiple image (slice) uploads, longitudinal performance history, and user specified alerts.
