Registration process for a set of sections from an infant patient (Patient 8 in Table 1). (a) The original CT image. (b) The original TEE image. (c) The result of basic registration. (d) The result of final registration. (e) The fusion result based on the basic registration. (f) The fusion result based on the final registration. (g) The fusion result obtained from the comparison algorithm VMI. (h) The fusion result obtained from the comparison algorithm ICPMI. Note: the yellow arrows in (e), (f), and (h) indicate the alignment of the heart valves. CT, computed tomography; TEE, transesophageal electrocardiography; VMI and ICPMI, comparison algorithms.
