Reduction of stent artifacts using high-frequency harmonic ultrasound imagingM E Frijlink
Biomedical Engineering, Erasmus MC, University Medical Center, Rotterdam, The Netherlands
Ultrasound Med Biol 31:1335-42. 2005..For the focused transducer, THI suppressed the second stent echo up to 14 dB compared with fundamental imaging. No significant reduction in stent artifact imaging was observed for the unfocused IVUS element...- Harmonic intravascular ultrasound imaging with a dual-frequency catheterMartijn E Frijlink
