Learning outcomes

Provide students with a basic physical knowledge of Computed Tomography and with the main techniques of reconstruction from projections, included the visualisation techniques. Analyze the radiation protection problems related to the use of CT. Analyze the methods of quantification of the image quality and his relationship with the operational parameters of the CT unit.

Syllabus
