Abstract:
1. A method for displaying images of a cyclically moving structure in a body of a living subject, comprising the steps of selecting a gating point in a motion cycle of said structure; acquiring data of said structure using a catheter having an imaging device and a position sensor; acquiring position data comprising location and orientation coordinates of said imaging device of said catheter; outputting said data of said structure and said position data to define an output of said data of said structure and an output of said position data, respectively; synchronizing said output of said data of said structure with said output of said position data relative to said gating point to define synchronized data of said structure and synchronized position data, respectively, said step of synchronizing further comprising determining a time offset between said output of said data of said structure and said output of said position data relative to said gating point; adjusting said time offset with respect to an interfering signal and acquiring images such that said images are acquired without interference; repeating said step of synchronizing said output of said data of said structure with said output of said position data relative to said gating point; and concurrently displaying gated images derived from said synchronized data of said structure in registration with said synchronized position data at said gating point in said motion cycle.
