The course aims to help students understand:
•the use of x-rays in producing diagnostic images;
•geometric factors in Radiology;
•x-beam modulation parameters and the main devices influencing the formation of radiographic image;
•the concept of radiographic image quality;
•the main correlations and differences between traditional and digital radiographic image.
•Production of x-rays;
•Notes on the interaction of x-rays with matter;
•Radiological image formation;
•Geometric factors in Radiology;
•Radiological projection concept;
•Main, central and normal x-beam;
•Magnification, deformation and distortion of the object;
•Geometric unsharpness and the Heel effect;
•Voltage, current, time: relationships and effects in conventional and digital radiology;
•Collimators, diffusion grids and other procedures to contain the scattering;
•Concept of contrast, sensitivity, exposure latitude and spatial resolution;
•Main correlations and differences between traditional radiography and digital radiography both direct and indirect;
•Guidelines for a correct analysis of the radiographic image quality.

Written exam concerning the entire course consists of 10 open questions to meet in 90 minutes. In particular, 4 questions are proposed for the module "Radiological Information Systems, processing and archiving of images," 3 questions for the module of"Physical-geometric assumptions for radiological imaging" and 3 questions for the module “Radiodiagnostic equipment and quality control".
The questions for each module are assessed by a vote of thirty by the specific teacher.
The Teaching Coordinator verbalizes the average grade resulting from the votes held by each module to the following rules:
- The test is considered passed if the average of the marks obtained in 3 modules is equal to or greater than 18/30;
- The minimum rating of each module that helps to determine the overall average rating for the course is 16/30;
- If the vote of a module is less than 16/30, the student is required to repeat the whole exam;
- A student who achieves an overall average rating in the script at or greater than 25/30 may request an oral interview to supplement the evaluation.
