X–Ray and Tomography

Five different experiments exploring X–rays and tomography.

In 1963 and 1964 Allan Cormack published the theoretical foundations of computer tomography in the Journal of Applied Physics. In 1972 the first computed tomographic scanner was built by Godfrey Hounsfield who, together with Allan Cormack, was awarded the Nobel Prize in Physiology or Medicine in 1979. The basic idea of computerized tomography is the illumination of an object by X-rays from numerous different angles.

Our educational X-RAY APPARATUS (preferred with W TUBE or AU TUBE) allows the illumination of objects by X-rays. The resulting 2D-projections are visualized at the fluorescence screen. These projections have a relatively low intensity. Therefore a camera of high sensitivity has to be used to record the various projections. Such a camera is implemented in the COMPUTED TOMOGRAPHY MODULE.

Each of the experiments explores a different part of X–Ray Physics:
1. Measurement and presentation of a computed tomogram with the computed tomography module
2. Computed tomography of simple geometrical objects with the computed tomography module
3. Medical basics of computed tomography with the computed tomography module
4. Determining absorption coefficients and Hounsfield units with computed tomography with the computed tomography module
5. Computed tomography of biological samples with the computed tomography module
