    • Presenting intravascular images and angiographic images co-registered on a display. As an imaging catheter is pushed through an occlusion, a center point of the catheter and an outline of the vessel wall can be displayed. A physician can see where the catheter is crossing the occlusion within the vessel. The physician can determine what path the catheter is taking the through occlusion. Methods include extending an imaging catheter through the occlusion, determining a location of a wall of the vessel relative to a center point of the catheter, obtaining a position of the catheter within a lumen of the vessel via angiography, and displaying the catheter crossing the occlusion by co-registering the location of the wall, the position of the catheter within the lumen, and the lumen on a display.
    • 呈现在显示器上共同登记的血管内图像和血管造影图像。 当成像导管被推过闭塞时,可以显示导管的中心点和血管壁的轮廓。 医生可以看到导管穿过血管内的闭塞。 医生可以确定导管穿过闭塞的路径。 方法包括通过闭塞延伸成像导管,确定血管壁相对于导管的中心点的位置,通过血管造影术获得导管在血管腔内的位置,并显示穿过闭塞的导管 通过共同对齐壁的位置,导管在管腔内的位置和显示器上的内腔。
