Learning outcomes

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.

Assessment methods and criteria

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.
