Catheter orienting markers

A method for determining the orientation of a device, the method comprising:

• 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;
• inserting the device into a vessel;
• imaging the device to capture an image of the device in an imaging plane;
• and
• processing the captured image to determine an orientation of the device relative to the imaging plane based on said markers.

A system for determining the orientation of a device, comprising:

• a processor;
• and
• a computer readable storage medium instructions that when executed cause the computer to:
• receive a captured image of an externally imaged 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;
• and
• process said captured image to determine an orientation of the device relative to an imaging plane of the captured image.
