Learning outcome

After completing the course, the student should:

• Know the function of the different parts of an ultrasound scanner
• Know how to use a standard ultrasound scanner, including archiving recordings
• Have detailed knowledge on the different imaging modalities (m-mode, B-mode, 2D, 3D, Doppler, contrast)
• Be able to apply this knowledge to explain limitations and sources of error in the different modalities
• Know limitations and errors when using the Doppler-effect to measure blood velocities and flow, and in estimation of pressures in different parts of the cardiovascular system
• Know how ultrasound can be applied in clinical medicine and research with emphasis on cardiology
• Know how high-frequency ultrasound can be applied in experimental research
• Understand the physical principles behind the use of ultrasound in medical imaging
• Know the risks associated with medical ultrasound, and the formal regulations that apply.

Learning methods and activities

The course will be held as an intensive course over 2 weeks 4 weeks apart; Lectures, practical demonstrations and five exercises. Lectures will be in english if there are international participants, if not, Norwegian will be the language of the course. Mandatory participation in regular study groups in two separate weeks. Image analysis and data organization. A minimum of 5 students required to conduct the course.

Compulsory assignments

• Exercises

Further on evaluation
