    • PROBLEM TO BE SOLVED: To provide a method and apparatus for bringing an optical coherence tomographic (OCT) image and an intravascular ultrasound (IVUS) image with the same orientation and magnification into registration.SOLUTION: A method for bringing an IVUS and an OCT image into registration comprises: obtaining an IVUS image of an area of a lumen (S178); obtaining an OCT image of the same area of the lumen (S182); determining the same asymmetry in each of the IVUS and OCT images; overlaying the IVUS and OCT images and rotating them with respect to each other until the asymmetry in each of the IVUS and OCT images are in registration (S194), and determining the angle of rotation that resulted in the registration. The probe for OCT and IVUS imaging includes: a sheath having a first end and a second end and a wall portion defining a lumen; a marker that is opaque to light and ultrasound located between the first end and second end; and an IVUS/OCT probe head positioned within the sheath.
    • 要解决的问题:提供一种用于使相同取向和放大的光学相干断层摄影(OCT)图像和血管内超声(IVUS)图像进行配准的方法和装置。解决方案:使IVUS和OCT图像的方法 注册包括:获得管腔区域的IVUS图像(S178); 获得腔内相同区域的OCT图像(S182); 确定每个IVUS和OCT图像中相同的不对称性; 覆盖IVUS和OCT图像并相对于彼此旋转,直到每个IVUS和OCT图像中的不对称性被配准(S194),并确定导致注册的旋转角度。 用于OCT和IVUS成像的探针包括:具有第一端和第二端的护套和限定内腔的壁部分; 位于第一端和第二端之间的对光和超声波不透明的标记; 以及位于护套内的IVUS / OCT探头。
