Abstract

Image guidance of minimally invasive cardiac interventions can be augmented by registering together different imaging modalities. In this paper, we propose a method to combine three modalities: X-ray fluoroscopy, trans-esophageal ultrasound and pre-procedure MRI or CT. The registration of the pre-procedure image involves a potentially unreliable manual initialisation of its position in an X-ray projection view. The method therefore includes an automatic correction using the esophagus location as an additional constraint. We test the method in a phantom experiment and find that initialising the pre-procedure image with up to 9mm offset from its correct position results in a 92% registration success rate. The esophagus constraint improves the capture range in the out-of-plane direction, which simplifies the manual initialisation.
