Learning outcomes
|
The subject provides the students basic information about imaging systems in medicine. Students obtain basic information from the optics, imaging sensors and digital cameras, image acquisition, processing and analysis, binary morphology, image filtration in space and frequency domain. Basics of 3 imaging methods - ultrasound, CT and magnetic resonance RT will be lectured.
By graduating this subject, students obtain basic information about diagnostics procedures problematic and evaluation and diagnostic medical instruments connection to computers and also obtain an introduce to the basic diagnostic quantities processing and their implementation in computers.
