The concept of PC-MRA is often difficult, but essential for practicing engineers and scientists working in MR related areas. The concepts are better understood by uniquely combining the physical principles of fluid flow and MR imaging, laid out by modeling the theory and applications using a commonly used software tool MATLABŪ. The book starts with a detailed theory of PC-MRA followed by a description of various image processing methods, including detailed MATLAB codes used for their implementation. The flow concepts in the context of MR imaging are explained using MATLAB based simulations. 410 0$aSpringerBriefs in Electrical and Computer Engineering,$x2191-8112 606 $aBiomedical engineering 606 $aMedical physics 606 $aRadiation 606 $aCardiac imaging 606 $aBiomedical Engineering and Bioengineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T2700X 606 $aMedical and Radiation Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P27060 606 $aCardiac Imaging$3https://scigraph.springernature.com/ontologies/product-market-codes/H29071 615 0$aBiomedical engineering. 615 0$aMedical physics. 615 0$aRadiation. 615 0$aCardiac imaging. 615 14$aBiomedical Engineering and Bioengineering. 615 24$aMedical and Radiation Physics. 615 24$aCardiac Imaging. 676 $a616.0754 700 $aSuresh Paul$b Joseph$4aut$4http://id.loc.gov/vocabulary/relators/aut$0764147 702 $aSubha GR$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910254200403321 996 $aUnderstanding Phase Contrast MR Angiography$92525664 997 $aUNINA
