The phantom retains many of the tests and features offered in the other Catphan® models including the CTP515 Low Contrast Module and integrated case mounting system.
Other test objects have been refined in this development including the addition of test patterns up to 30 lp/cm in the new CTP714 High Resolution 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. The Cathan® 700 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.
