- W2004258406 abstract "A method to measure transverse blood flow, based on correlation between consecutive radio frequency (RF) signals, has been developed. Currently, we are implementing the method for an intravascular (IVUS) array catheter. In this paper, the acoustical beam (line-spread function, LSF) was experimentally measured and compared with the simulated one. Next, the experimental LSF(E) was convolved with a matrix of white noise to produce RF(E) signals. Decorrelation pattern from the RF(E) signals was compared with the correspondent autoconvolution of the LSF(E) and a good agreement was found. We conclude that the transverse decorrelation pattern of the IVUS array catheter can be assessed from the properties of the acoustical beam." @default.
