Supporting data for "Towards 3-D Plus Time Ultrafast Ultrasound Investigation of Human Arterial Wall: Wave Physiology, Computational Mechanics, and Image Formation"

Supplemental data

1. Supplemental information (text)

2. Supplemental videos of a newly observed extension wave as
well as the well-known pulse wave in the artery wall. Pulse wave propagation
from the heart (left) to the head (right) sides in videos. Actual inter-frame
duration is 1 ms.

Video1-1: pulse wave at a playback speed of 30
frames/second.

Video1-2: pulse wave at a playback speed of 3 frames/second.

Video2-1: extension wave at a playback speed of 30
frames/second.

Video2-2: extension wave at a playback speed of 3
frames/second.

3. UI for finite-element simulations. Users can download and
easily input key parameters to reproduce or simulate natural wave propagation.
Computational time for an isotropic case is about 16 hours in a standard
desktop PC. And anisotropic cases will take even more time. You are welcome to
give us feedback on new functions of this UI.

The source code (.m file) is included for test in 'COMSOL
Multiphysics with MATLAB' software. Please note that the auto-saved source code
contains all log information, which reduces its readability.

4. MATLAB code ('TheoreticalCalculation.m') for theoretical
calculation of natural wave speeds.

补充数据

1. 补充信息（文本）

2. 新观测到的扩展波以及动脉壁中著名的脉冲波的视频资料。视频展示了从心脏（左侧）至头部（右侧）的脉冲波传播过程。实际帧间持续时间为1毫秒。

Video1-1：以每秒30帧的播放速度呈现的脉冲波。

Video1-2：以每秒3帧的播放速度呈现的脉冲波。

Video2-1：以每秒30帧的播放速度呈现的扩展波。

Video2-2：以每秒3帧的播放速度呈现的扩展波。

3. 有限元模拟的用户界面。用户可以下载并轻松输入关键参数，以再现或模拟自然波传播。在标准台式电脑上，各向同性情况下的计算时间约为16小时。各向异性情况所需时间更长。我们热切期待您对我们用户界面的新功能提出宝贵意见。

4. 包含于'COMSOL Multiphysics with MATLAB'软件测试中的源代码（.m文件）。请注意，自动保存的源代码中包含了所有日志信息，这可能会降低其可读性。

5. 用于自然波速理论计算的MATLAB代码（'TheoreticalCalculation.m'）。
