Giriprasad, P.V. SrideviProblem statement: Valvular regurgitation is recognized as the central cause of morbidity and mortality. Even though the clinician can detect the presence of regurgitation by mere physical examination; diagnostic methods become inevitable while estimating the severity of valvular regurgitation and in the transformation of cardiac chambers as in reaction to the volume overload condition. Lately, a promising new technology, the … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,220 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDF Cite
