Claim One:
1. A method for displaying a medical image of a lumen of a biological structure, the method comprising providing at least one computer-readable medium having instructions stored thereon which, when executed by a computing device, cause the computing device to carry out operations comprising: obtaining image data of a lumen of a biological structure from an imaging device; correcting the image data for translational distortions, wherein correcting is accomplished without reference to another data set and wherein correcting comprises compensating for device angular distortion, wherein compensating comprises: aligning a reference position of a first frame with a catheter center position of a neighboring frame; determining a longitudinal distance between neighboring frames; evaluating an angle between two vectors, wherein a first vector is defined by a distance between a reference position in a first frame and a catheter center position in a neighboring frame, and a second vector is defined by a distance between a reference position in a first frame and a reference position in said neighboring frame; and rotating the neighboring frame about an axis through a value corresponding to the angle between the said two vectors, wherein said axis is located in a plane defined by the neighboring frame, intersecting the catheter center position of the neighboring frame, and oriented perpendicular to a plane in which said first vector and second vector are located; and displaying a corrected image.
