Metric Options: Counts1 Year3 YearSelecting 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.

Article Description
We present a novel integrated mechanical and structural photoacoustic imaging (IMS-PAI) for atherosclerosis characterization. A quasi-continuous laser with pulse width of 22 ns and repetition frequency of 25 KHz was used to realize simultaneous acquisition of PA phase and temporal intensity. An algorithm utilizing sound propagation model in conjunction with temporal PA intensity was developed and applied to correct the phase deviation caused by uneven tissue surface. Integration of en-face mechanical and in-depth structural PA imaging was verified by a tissue-mimicking phantom. Moreover, complementary visualization of en-face viscoelasticity distribution and in-depth structural anatomy of an atherosclerotic tissue was achieved, which was consistent with the histology. The results demonstrated the IMS-PAI has an attractive synergy in comprehensive atherosclerosis characterization.
