Navigation system for cardiac therapies using gating

a navigation system and cardiac therapy technology, applied in the field of image guided surgery, can solve the problems of not helping the catheter in actually guiding a medical device to a targeted tissue area for medical treatment, exposing both the patient and the operating room staff to radiation, and reducing the exposure to fluoroscopy. , to achieve the effect of improving outcomes, reducing radiation exposure, and ensuring accuracy

Abstract

An image guided navigation system for navigating a region of a patient which is gated using ECG signals to confirm diastole. The navigation system includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of a patient. The tracking device tracks the location of the instrument in a region of the patient. The controller superimposes an icon representative of the instrument onto the images generated from the imaging device based upon the location of the instrument. The display displays the image with the superimposed instrument. The images and a registration process may be synchronized to a physiological event.

Description

FIELD OF THE INVENTION

[0001] The present invention relates generally to image guided surgery, and more specifically, to systems and methods for using one or more medical images to assist in navigating an instrument through internal body structures, in particular for navigating a catheter in a moving body structure, such as the heart, during a surgical procedure.BACKGROUND OF THE INVENTION

[0002] Image guided medical and surgical procedures utilize patient images obtained prior to or during a medical procedure to guide a physician performing the procedure. Recent advances in imaging technology, especially in imaging technologies that produce two, three, and four dimensional images, such as computed tomography (CT), magnetic resonance imaging (MRI), isocentric C-arm fluoroscopic imaging, positron emission tomography (PET), and ultrasound imaging (US), has increased the interest in image guided medical procedures.

[0003] At present, cardiac catheterization procedures are typically performed...
