554821 Computerised Tomography Module

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) • Screen resolution 1280x1024 (TrueColor) • USB 2.0 port Technical Data: • Mounting of the object at the goniometer of the X-ray apparatus • Maximum object size: approx. 8 x 8 x 8 cm³ • Object resolution: approx. 0.25 mm • Angular resolution: 1 - 720 2D projections per computed tomogram • Size of the computed tomogram: 200 - 340 pixels per dimension • Connection of the module to the computer: USB 2.0 port • Connection of the X-ray apparatus to the module: USB 2.0 port • Separate video output: Cinch (CCIR) • Mains voltage: 230 V, 50/60 Hz • Dimensions: 53 cm x 34 cm x 24.5 cm • Weight: 13.5 kg Scope of delivery: • Computed tomography module • Computed tomography software • Object (small dried animal, e.g. frog) • Cell (e.g. for water) • Object holder including polystyrene holder • USB cable INSTRUCTIONS FOR USE PLEASE CLICK HERE EXPERIMENT INSTRUCTIONS PLEASE CLICK HERE
