Computed Tomography Module

Records the 2D-projections of an object illuminated by x-rays within a few minutes. During the recording of the 2D-projections, the e-learning software visualizes the back projection process in two or three dimensions alternatively. After the scan the complete 3D-object is available to be viewed (rotating, zooming, transparency effects, projections, illumination similar to the Heidelberger ray-tracing model).Well-resolved images of various objects can be obtained in spite of the simple measuring method and the low energy of the x-ray radiation (35 keV) from the educational x-ray apparatus. The 3D-computed tomogram of various objects can be evaluated qualitatively and quantitatively. The learning involved in the preparation of the scanning process and image evaluation is emphasized. Additionally, a suitable x-ray apparatus (554 811USB or 554 801, X-ray tube W 554 864) and a powerful computer are required.

PC Requirements
The real-time recording and evaluation of a computed tomogram need a powerful CPU and graphics card.

For performing CT scans the following minimum requirements apply:
• Windows XP SP2 or Windows Vista (32 bit or 64 bit)
• Dual-Core CPU 2 GHz
• 2 GB RAM
• DirectX 9 compatible 3D-graphics card with shader model 3 support and 256 MB RAM
(Nvidia GeForce 7600 / 8600 or better)
• creen resolution 1024x768 (TrueColor)
• USB 2.0 port

For larger computed tomograms we recommend a more powerful PC:
• Windows Vista (32 Bit or 64 bit)
• Quad-Core Processor 2,4 GHz
• 3 GB RAM
• DirectX 9 compatible 3D-graphics cards with shader model 3 support and 512 MB RAM
(ATI Radeon 3850 /Nvidia GeForce 8800 or better)
