INTRALUMINAL AND EXTRALUMINAL IMAGE REGISTRATION

INTRALUMINAL AND EXTRALUMINAL IMAGE REGISTRATION

Systems and computer-implemented methods of registering positions of a temporal sequence of intraluminal sensing device data (1011..m) to positions along a guidewire (104) in a temporal sequence of extraluminal image frames (1051..n) include: determining (S120) a position of a sensing portion (106)...

Zusammenfassung:Systems and computer-implemented methods of registering positions of a temporal sequence of intraluminal sensing device data (1011..m) to positions along a guidewire (104) in a temporal sequence of extraluminal image frames (1051..n) include: determining (S120) a position of a sensing portion (106) of the intraluminal sensing device (102) along the guidewire (104), based on a matching of image intensity values determined at positions along the guidewire (104) in the extraluminal image frame (1051..n), with an expected intensity pattern (107) representing a portion of the intraluminal sensing device (102); and mapping (S130) a position of an intraluminal sensing device data (1011..m) generated contemporaneously with the extraluminal image frame (1051..n), to the determined position along the guidewire (104).
