Objectives

Computer aided diagnosis can be defined as the the diagnosis made by the radiologist supported by a computer based medical image analysis that acts as a second opinion system. The course aims at giving the students the knowledge and ability to develop image enhancement, image analysis and classification systems useful in CAD environments.

Learning outcomes and competences

 

To contribute to develop the capacity of the students to work autonomously and in group, to do bibliographic research, to prepare written reports and to deliver oral presentations.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Previous knowledge:

Biomedical Image Analysis, Signal Processing, Matlab

Groups of 4 students will present five CAD case studies .

Software

Evaluation Type

Distributed evaluation with final exam

Designation	Weight (%)
Exame	50,00
Trabalho laboratorial	50,00
Total:	100,00

Eligibility for exams

To reach a passing grade during the semester

Calculation formula of final grade

The final mark (NF) has 2 components: CF - Evaluation during the semester (50%) which includes the study, analysis and 2 assigments on pattern recognition and image analysis (PR1+PR2), by groups of 2 students and a challenge (CH) by groups of 4 students.; 2.EX -Exam (50%), which is a written exam with problems about the taught material. A student to be approved, have to have a mark greater or equal to 8.0 in each of the components CF and EX, and NF has to be greater or equal to 10. The corresponding expressions are:

CF = 0.2*PR1+0.2*PR2+0.6*CH

NF=0.5*CF+0.5*EX, para EX >= 8.0

NF=EX para EX < 8.0

Examinations or Special Assignments

Case studies: Challenge (group of 4 students)
Two Assignments (2 students)

Special assessment (TE, DA, ...)

The students are submitted to the same type of evalutation and with the same rules  of the other students with a normal statue

Classification improvement

In the same academic year, the students may apply to improve the mark for the written exam only.
