Experimental results for catheter and sheath OA measurements. (a) Catheter and (b) sheath measurements over one rotation. (c) Catheter and (d) sheath measurements from a 3 cm pullback performed in vivo, with the OA values shifted and scaled to the range of [0,1] and depicted in true RGB (where the Q component is mapped to the R channel, and the U and V components the G and B channels, respectively). These images demonstrate the consistency of these measurements even during in vivo imaging.
