Image-guided catheterisations are an important clinical tool for cardiovascular diseases. In order to increase the accuracy of the procedure with an additional MRI roadmap, a 3D high resolution scan and additional respiratory information are required. Here we present a method that records all the necessary information during a single whole-heart scan with a prospective respiratory resolved acquisition scheme. Moreover, an affine model to describe the breathing motion can be obtained from the same acquired data. Validation on volunteer data yielded a maximum target registration error of less than 3.4mm.
