Example of deformable registration process. (a) Indication of the placement of the line profile that appears over time in the right. This particular frame is end-expiratory and appears in (b) as the pink vertical line. (b) Intensity profile over time for this ungated acquisition. Red lines indicate diastolic phase and the green colored lines indicate systolic phase. (c) Intensity line profiles after self-gating to diastole (all red lines). (d) After self-gating to systole. (e and f) Intensity line profiles after deformable model-based registration (DMBR).
