1. A catheter treatment system, comprising:
- an X-ray imaging apparatus;
a magnetic resonance imaging (MRI) apparatus;
a patient support apparatus configured to move a patient secured thereto between examination positions with respect to the X-ray imaging apparatus and the MRI apparatus; and
an image processor configured to fuse images obtained by the X-ray apparatus and the MRI apparatus.

Abstract
A system and method of treating tachycardias and similar syndromes by the use of catheter ablation of scar tissue is described. The patient is imaged by an X-ray device and an MRI device and the images are fused so as to facilitate identification of scar tissue. The fused image or the X-ray image with treatment areas identified is used to guide the positioning of a catheter with respect to the location to be treated. Guidance of the catheter may be use of X-ray images of the catheter tip, or acoustic or magnetic sensors. After positioning, the catheter is used to ablate body tissue. A further MRI image may be obtained to evaluate the results of the treatment.

12. A method of treating a patient, the method comprising:
-
placing a patient on a patient support apparatus; positioning the patient support apparatus with respect to one of a first imaging modality or a second imaging modality; operating one of the first imaging modality or the second imaging modality to collect data suitable for image reconstruction; moving the patient to the other of the first imaging modality or the second imaging modality so as to maintain a known orientation of the patient with respect to the first imaging modality and the second imaging modality; operating the other of the first imaging modality or the second imaging modality to collect data suitable for image reconstruction; reconstructing images from the first imaging modality and the second imaging modality and fusing the image from the first imaging modality and the second imaging modality so as to form a fused image; and using the fused image to identify a region of the patient to be treated. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A treatment system, comprising:
-
means for obtaining soft-tissue X-ray images; means for obtaining magnetic resonance images; means for transferring a patient between the means for obtaining soft-tissue X-ray images and the means for obtaining magnetic resonance images while maintaining a known orientation of the patient with respect to each of the means for obtaining the images; fusing the images obtained from the means for obtaining soft-tissue X-ray images and the means for obtaining magnetic resonance images; and means for treating a cardiac syndrome.
