Lab 7: Fan Beam vs. Cone Beam CT
In this lab exercise students observe important differences between fan beam and cone beam CT imaging. Using apertures of different width, students scan a finger phantom which contains fingers of different diameter and the same density. From the reconstructed images students measure attenuation coefficients in the fingers and observe how the values differ as the aperture changes from wide cone to narrow fan.
Lab 8: Dual Energy CT
In this lab exercise students learn how Dual Energy CT can be used to discriminate structures and objects according to their absorption characteristics at various imaging energies. Students use light of different wavelengths (energies) to scan and measure the attenuation values of colored objects in a phantom. This exercise helps students understand the importance of the energy dependence of tissue contrast in x-ray medical imaging.
Lab 9: Emission CT
In this lab exercise students investigate emission CT and the density corrections that are applied based on transmission CT images. Students work with an emission phantom which contains neutral density objects and an object which fluoresces under UV light. A transmission scan (red light) of the phantom is performed followed by an emission scan of the same phantom under UV illumination. The results of the transmission scan are then used to correct emission values in the emission CT image.
