Function and the responsibility of an ultrasound and doppler imaging systems. Imaging modes and device block diagrams. RF signal and the Hilbert transform. Technical parameters and system constraints.


Students must complete each exercise and execute tasks in a computing environment Matlab. During the semester is allowed one excused absence. In the last week of the semester there is planned written test. The test is composed of questions according to the list of topics. The test has 40 questions and the test result is evaluated according to ECTS grading scale, ie. A-E, 100-50 points. Fewer than 50 points indicates degree F. The test scoring issues 1 (27x) 3 (1x), 5 (10x) and 10 (2) points, ie. the difficulty. Most of the questions is provided as a choice of one of three answers (there is always one answer correctly) - namely the question for 1 point. Other issues for the higher number of points are usually implemented as issues where the need for a complete response in the form of a block diagram or calculation simple relationship, etc.
