Abstract

Abstract:

IntraVascular UltraSound (IVUS) imaging can provide information of the coronary atherosclerotic plaque. It allows the doctor to make comprehensive and accurate evaluation of diseased vessel. Some ultrasound data collecting devices for imaging system exhibited insufficient data transfer speed, high cost or inflexibility, so the authors presented a high speed data transfer and imaging method for intravascular ultrasound. After being collected and processed, ultrasound data was transferred to computer through USB3.0 interface. In addition, logarithmic compression and digital coordinate conversion were applied in computer before imaging. Data transmission experiment shows that the transfer speed always stays around 2040Mb/s. Finally, phantom imaging was conducted to demonstrate the performance of the system. It shows a clear pipe wall and a smooth luminal border.

摘要：

血管内超声（IVUS）成像技术能提供动脉粥样斑块的组织信息，便于医生对血管病变作出全面、准确的评价，已广泛应用于心血管疾病的诊断。针对现有的超声数据采集装置在传输速度、成本、灵活性等方面的不足，提出并实现了一种高速的血管内超声成像数据传输及成像方法。采集到的血管内超声信号经过处理后通过高速USB3.0接口传输到PC端，再进行对数压缩以及坐标变换等操作，最后实时显示图像。实际传输速率统计显示，传输速度稳定在2040Mb/s上下。血管仿体成像实验中管壁组织清晰、内腔轮廓平滑。
