摘要：
The present invention generally relates to methods, devices and systems for determining the rotational orientation of a device. The invention can involve providing a device comprising a plurality of markers, wherein each marker within the plurality of markers differs from an adjacent marker by size, shape, and/or position on the device. The invention can also involve inserting the device into a vessel and imaging the device to capture an image of the device in an imaging plane. The invention can further involve processing the captured image to determine an orientation of the device relative to the imaging plane based on the markers.
