Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
Although high frame rate (HFR) imaging could be a promising technique for a better assessment of myocardial function, the higher temporal resolution comes with decreased image quality, which affects the accuracy of speckle tracking echocardiography (STE). Since several adaptive beamforming algorithms have already been proposed to improve image quality, the aim of this study was to assess to what extent this impacts the accuracy of HFR STE. Simulated datasets were used to compare 7 coherence-based beamforming schemes. The STE results were similar for different beamformers with root mean square errors between 0.36 and 0.50%. Next, in vivo apical 4-chamber views were recorded from 3 healthy volunteers using the same beamforming schemes. The related strain curves were similar for the different beamforming methods and the end-systolic values showed no significant difference among beamformers and volunteers. In conclusion, our findings suggest that the choice of beamforming method does not significantly affect HFR STE in a clinical setting.
