17AMBUDS - Ultrasound and Doppler Imaging Systems

Code Completion Credits Range Language
17AMBUDS KZ 2 1P+1C English
Department of Biomedical Technology

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.

Syllabus of lectures:

1.Introduction to ultrasound and doppler imaging systems, mathematical apparatus, signal processing.

2.Ultrasound probes and transducers, piezoelectric phenomenon.

3.Display modes - A, M (TM), B, C, Q, and their properties.

4.Ultrasonic probe. Linear and sector - resolution, types and principles focusing of ultrasound beam.

5.Doppler effect and its use in ultrasound imaging technique.

6.Individual device blocks and their specifications.

7.3D and 4D techniques using ultrasound techniques.

Syllabus of tutorials:

1.The theory of Hilbert transform

2.Detection of the signal envelope - application of Hilbert transform.

3.Coordinate systems - Cartesian and polar coordinates.

4.Image reconstruction of ultrasound beam - RF data processing and display.

5.Analysis of ultrasound data in Matlab and calculate their parameters - angles and distance shooting.

6.Reconstruction of ultrasound data - B mode. Converting from polar to Cartesian coordinates and interpolation of data.
