Faculty Applied Sciences Department IST/Imaging Science and Technology Date 2012-01-25 Abstract We demonstrate the feasibility of intravascular ultrasound (IVUS) chirp imaging as well as chirp reversal ultrasound contrast imaging at intravascular ultrasound frequency. Chirp excitations were emitted with a 34?MHz single crystal intravascular transducer and compared to conventional Gaussian-shaped pulses of equal acoustic pressure. The signal to noise ratio of the chirp images was increased by up to 9?dB relative to the conventional images. Imaging of contrast microbubbles was implemented by chirp reversal, achieving a contrast to tissue ratio of 12?dB. The method shows potential for intravascular imaging of structures in and beyond coronary atherosclerotic plaques including vasa vasorum Subject biomedical transducersbiomedical ultrasonicsblood vesselschirp modulationmedical disordersultrasonic transducers To reference this document use: http://resolver.tudelft.nl/uuid:8f871146-6c21-49db-9b33-f981d852f5e2 DOI https://doi.org/10.1063/1.3679375 Publisher American Institute of Physics ISSN 0003-6951 Source http://link.aip.org/link/doi/10.1063/1.3679375 Source Applied Physics Letters, 100 (4), 2012 Part of collection Institutional Repository Document type journal article Rights (c) 2012 The Author(s)American Institute of Physics Files PDF ApplPhysLett_100_0437031.pdf 1.45 MB Close viewer /islandora/object/uuid:8f871146-6c21-49db-9b33-f981d852f5e2/datastream/OBJ/view
