“…The measurement is controlled from a single standard PC running Matlab (The MathWorks Inc., Natick, MA) under Linux. The ultrasound acquisition is carried out using the experimental ultrasound scanner RASMUS [18], which is controlled from the PC through an ethernet connection. It is a realtime ultrasound system providing full control of the transducer both in transmit and receive.…”

“…A number of approaches have been reported for ultrasound imaging using both linear array and phased array [7][8][9][10][11]. One-dimensional ultrasound transducer arrays are used to get 2D images, and two-dimensional transducer arrays have been applied to produce 3D ultrasound images [12][13][14].…”

Abstract-Blood velocity estimates using conventional color flow imaging (CFI) or Doppler techniques are angle dependent. One of the proposed techniques to overcome this limitation is the Transverse Oscillation (TO) method, which also estimates the lateral velocity components. The performance of this is evaluated on a commercial platform. Beamformed data are acquired using a commercial BK Medical scanner as opposed to the previously reported results obtained with the experimental scanner RASMUS. The implementation is evaluated using an in-house circulating flow rig by calculating the relative mean standard deviation and bias of the velocity components. The relative mean standard deviation decreases as the number of shots per estimate increases and a value of 5% is obtained for 64 shots per estimate. For a center frequency of 5 MHz at 60• , 75• , and 90• , the relative mean bias varies from 21% to 27% and is lowest at a transmit focal depth close to the center of the vessel. The present performance is comparable with the results from the experimental scanner and simulations. It is obtained with only few changes to the conventional CFI setup and further optimization can improve the performance. This illustrates the feasibility of implementing the TO method on a commercial platform for real-time estimation.
