The PolyCT conversion kit is equipped with laser alignment, providing users with support for installation and alignment so that they do not have to interact with the system software or mechanics. Either a magnet or a suction cup mechanism is used to attach the device. PolyCT is either clamped directly into an existing CT chuck or a centering adapter device is used to attach it to a flat rotary plate. The objects to be tested are then fastened into the universally adaptable specimen holders.
By using individual centers of rotation, the PolyCT kit optimizes its use of the area of the X-ray detector. This way, fewer angle increments are required in comparison with standard measurement procedures. With one-third of the detector, a regular scan can be carried out with up to two-thirds fewer images, which has a positive effect on the measurement period. Alternatively, if the amount of angles remains the same, image quality improves. Its simple operation and precise mechanics make the kit easy to use in every laboratory.
Fraunhofer reconstruction software is used to process the measurement data. This means that users do not need to interact with existing system architecture. The recorded CT data are processed into volume data on a separate computer system. To do this, the software has an interface for the system data format, so the application does not require any user interaction. This step is either carried out automatically by a folder monitoring function or by manually selecting the PolyCT scan data. The volume data can be imported directly into all commonly used visualization tools.
