In this exemplary embodiment, the steps of the procedure 90a are schematically illustrated in FIG. 2A and outlined below. First, in step 106, the physician places ultrasound catheter 55 in one chamber of the patient's heart and obtains one or more images of an adjacent chamber using the ultrasound catheter 55. For example, the physician inserts ultrasound catheter 55 into the right atrium 30 (FIG. 2C) and aims the ultrasound beam 57 projected from catheter 55 at an adjacent chamber, for instance, the left atrium 10 and uses the catheter 55 to acquire ultrasound images (two-dimensional “2D” ultrasound images) of the left atrium 10 and surrounding structures. The position sensor (not shown) used on the ultrasound catheter 55 and its associated location system (not shown) allow for accurate location determination (determination of position coordinates and orientation coordinates) of the position sensor and catheter 55. For example, the position sensor allows for a portion of catheter 55 to be accurately tracked and navigated using three dimensions of position coordinates (X, Y and Z coordinate axis directions) and at least two dimensions of orientation coordinates (yaw and pitch) to include up to three dimensions of orientation coordinates (yaw, pitch and roll). Accordingly, since the location coordinates (position coordinates and orientation coordinates) for a portion of the catheter 55 are determined using a location system (not shown) operatively connected to the position sensor of the catheter 55, three-dimensional ultrasound slices are obtained using the 2D ultrasound images and their associated location coordinates for each pixel of each respective 2D ultrasound image.
Another embodiment of this method 90b in accordance with the present invention is illustrated in FIG. 2B and uses many of the steps outlined for the method 90a (FIG. 2A), and likewise the same reference numerals are used for the same method steps. However, an additional step, generally designated 112, is the pre-planning and simulation step, which are the same steps: calculating dimensions of features 115, determining paths for treatment 120, simulation the sheath insertion process 125, simulation of devices inserted through the sheath 130, verifying access to all points to be treated 135, designing the treatment plan 140, and monitoring procedure and providing guidelines 150 illustrated in FIG. 1A and outlined in detail previously above.
