摘要：
Fluoroscopic imaging of a patient's heart is performed by positioning a patient in a sterile field and imaging the heart using a x-ray fluoroscopy system within the sterile to produce a two-dimensional image. The two-dimensional image is simultaneously displayed on an operative display within or adjacent the sterile filed and on a display of a remote image processor outside the operative field. The two-dimensional image of the remote display is manually marked or annotated to show anatomical or treatment information which is simultaneously shown on the operative display. Alternatively, a patient's heart is imaged using a catheter to produce a real time image. The image is presented on a screen and sent to an image processor. Treatment parameters are input to the image processor, and the image processor calculates locations of a plurality of target treatment sites which are displayed on the screen. The catheter is advanced to position a treatment element on the catheter proximate a location of a target treatment site, where the actual position of the treatment element may differ from calculated location. After treating at the actual treatment position, an image processor calculates a difference between the positions of the calculated and actual treatment sites. The locations of all remaining target treatment may be recalculated by the image processor. Further alternatively, a patient's heart is imaged using a catheter to produce a real time image which is displayed on a screen. The image is also sent to an image processor where treatment parameters are input. The image processor then calculates safe regions and/or unsafe regions for performing a treatment or diagnosis within the heart based upon the inputted treatment conditions. The image processor superimposes information on the image on the screen to identify the safe and/or unsafe regions.Selon l'invention, la représentation fluoroscopique du cœur d'un patient est exécutée en positionnant un patient dans un champ
