血管内超声和血管内光声成像的结合已被提出用于提高动脉疾病的诊断。我们描述了一种新的扫描头设计，实现这样的多模态成像。申报器械有可能实现足够小的尺寸，用于临床血管内应用。该设计的目的是有效的图像数据采集，以促进实时三维成像和减少所需的激光脉冲重复频率。集成的扫描头由一个单一的元素，环形换能器的侧向超声传输，多模光纤与锥形反射镜的光学照明，和一个单一的聚合物microbial与机械扫描。给出了体模成像和部分实验结果。未来可以实现微阵列，以实现高帧率的血管内多模态成像。(C)2010年美国光学学会
The combination of intravascular ultrasound and intravascular photoacoustic imaging has been proposed for improving the diagnosis of arterial diseases. We describe a novel scan-head design for implementing such multimodality imaging. The proposed device has the potential to achieve a sufficiently small size for clinical intravascular applications. The design aims for efficient image data acquisition for facilitating real-time three-dimensional imaging and reducing the required laser pulse repetition frequency. The integrated scan head consists of a single-element, ring-shaped transducer for sideward ultrasound transmission, a multimode fiber with a cone-shaped mirror for optical illumination, and a single polymer microring with mechanical scanning. The phantom imaging and some experimental results are presented. A microring array can be realized in the future to achieve high-frame-rate intravascular multimodality imaging.
