1. A computer-implemented method for modeling a stimulation leadwire implanted in a portion of a patient anatomy, the method comprising: obtaining, by a computer processor, at least one image of at least a portion of the implanted stimulation leadwire; based on the at least one image, determining, by the computer processor, a relative position of the stimulation leadwire with respect to the portion of the patient anatomy; displaying, by the computer processor and in a display device, a model of the portion of the patient anatomy at coordinates of a coordinate system: and in accordance with the determined relative position, displaying, by the computer processor and in the display device, a model of the stimulation leadwire at coordinates of the coordinate system, which are offset from the coordinates of the model of the portion of the anatomy in accordance with the determined relative position of the stimulation leadwire: wherein: the stimulation leadwire includes a plurality of markers, wherein each marker is rotationally biased towards one point on or section of a perimeter of the stimulation leadwire, the perimeter extending about a center longitudinal axis of the stimulation leadwire; the determining of the relative position includes determining a rotational orientation of the leadwire about the center longitudinal axis by identifying a rotational positioning of the markers relative to each other and within and relative to the at least one image; and the determining of the relative position is performed based on a set of images of a portion of the leadwire including a respective image for each rotation of the leadwire by a certain number of degrees.
