The authors regret than an error was present in the legend to figure 5. The correct legend appears below:
- Fig. 5. (a) Conventional B-mode image and (b) image of the differentiated envelope between consecutive ultrasound beams at the 0th frame (time of R-wave) for participant A. (c, d) Normalized cross-correlations between the 0th and 1st frames where the correlation kernel was set as a red parallelogram on (a) and (b), respectively. (e) Estimated results of the longitudinal displacement of the intima–media complex (IMC) by the block-matching method, superimposed on the lateral M-mode image. The result using the differentiated envelope in the block-matching method is plotted as a red line and the result using the simple envelope is plotted as a blue line.
The authors would like to apologise for any inconvenience caused.

- Lateral M-Mode: Ultrasound Visualization of Displacement Along Longitudinal Direction at Intima–Media ComplexUltrasound in Medicine and BiologyVol. 49Issue 3
- PreviewQuantification of the dynamics of the carotid artery wall is useful in evaluating arteriosclerosis and atherosclerosis. As the carotid artery wall moves not only in the radial direction but also in the longitudinal direction, longitudinal movement should be considered in the analysis of the dynamic properties of the carotid artery wall. In this study, we propose a “lateral M-mode” method for visualizing the longitudinal movement of the intima–media complex (IMC). For the lateral M-mode, we set the target line in the longitudinal direction along the IMC and visualize the signals on the target line frame-by-frame by correcting the position of the target line along the radial displacement estimated by the phased tracking method.
