Objectives
The objective of this curricular unit is the acquisition of basic knowledge in Physics relevant to the activities involved in the operation, maintenance, or investigation of the equipment used in Medical Imaging. This knowledge includes basic Physics principles and the basic aspects of the engineering of the imaging types of equipment.
Learning outcomes and competences
By the end of the curricular unit, the students should attain proficiency in the following areas:
Basic principles in radiation Physics. Describe the structure of matter and its relation with radiation; describe the different types of radiation and their propagation; list the physics quantities and their units necessary to describe radiation and its propagation; describe the production and detection of radiation; describe the interaction of radiation with matter, particularly its use in medical imaging (x- and gamma-rays); explain the use of radiation in Medical Imaging; solve simple exercises in these subjects.
Basic concepts in medical imaging equipment. Enumerate the different imaging modalities; relate the modalities with the underlying physics mechanisms; identify the components and construct general block diagrams of the corresponding medical equipment; describe each modality's acquisition of an image.
Basic experimental Physics. Plan and perform didactic experiments: apply the Physics principles; define goals and procedures; carry out the experiments and collect the data; analyze the results; report the conclusions.
Calculus and data analysis. Use spreadsheets or small programs to analyze data from experiments and to solve problems in radiation Physics. Interpret and explain the information in technical specifications of the equipment. Use data sources, extract information regarding practical aspects of radiation physics: nuclide charts, decay diagrams, dose charts, attenuation graphs, etc.
Personal development. Work efficiently in a group; communicate with efficiency, written and orally. Develop autonomous work; self-and peer evaluation skills; critical thinking, and reasoning.

Teaching methods and learning activities
- Lectures (“aulas teórico-práticas”-TP) 1h/week. Lectures may consist of several activities: presentation and discussion of concepts; listing of the objectives for the subject under study and the corresponding reading assignments and homework; explaining the working principles of imaging equipment; simulations and experiments; problem-solving; continuous evaluation activities such as short tests.
- Laboratory classes (“práticas laboratoriais”-PL) 1x1h/week: simple laboratory experiments with x-rays (using a didactic x-ray apparatus).

Eligibility for exams
To achieve a successful continuous evaluation (CE), it is necessary to:
- Comply with the minimum attendance to each class type (75%);
- Accomplish at least 80% of all the proposed activities.
Calculation formula of final grade
The final grade (FM) is computed using
FM = 0,2 CE + 0,3 MT + 0,5 FE- CE the continuous evaluation grade;
- MT is the midterm test grade;
- FE the final exam grade, which must not be less than 10 (in 20).
Special assessment (TE, DA, ...)
By exam, under the applicable grading rules. The exam includes a component corresponding to the midterm test (MT).
Classification improvement
By exam, under the applicable grading rules. The exam includes a component corresponding to the midterm test (MT).
Observations
If the final exam grade is less than 10 (FE<10), then the final course grade (FM) will be the final exam grade (FM=FE).
