1. A system for treatment of a medical syndrome, the system comprising:
- an imaging modality configured to obtain data suitable for computing a computed tomographic (CT)-like image;
a computer system configured to;
calculate the CT-like image from the data obtained by the imaging modality pre-operatively, intraoperatively, or pre-operatively and intraoperatively;
identify from the CT-like image healthy tissue that is not intended to be damaged or treated;
distinguish the identified healthy tissue from all other types of tissue; and
segment the identified healthy tissue;
a display configured to display a colored, outlined, or textured image of the identified healthy tissue; and
a treatment device;
wherein the computer system is configured to inhibit operation of the treatment device at a predetermined minimum distance from the identified healthy tissue.

Abstract
A system and method of treating tachycardias and similar syndromes by the use of catheter ablation of tissue is described. A computed tomography (CT)-like image of the heart is obtained and processed to segment the various types of tissue. Papillary muscle areas are identified and displayed differently from the other nearby tissues so that the muscles can be avoided during treatment to avoid or minimize damage to the muscles during ablation treatment. Electrophysical data and scar tissue may also be identified in the image, which may be of the endoscopic type. The position of the catheter may be displayed as a synthetic image on the endoscopic view.

14. A method of treating a medical syndrome, the method comprising:
-
obtaining pre-operative imaging data using an imaging modality; computing, from the pre-operative imaging data, a three dimensional computed tomographic (CT)-like soft tissue image of an interior of a body of a patient in an area of interest; identifying a healthy region to be avoided in the area of interest; distinguishing the identified healthy region from all other types of regions in the area of interest; segmenting the identified healthy region to be avoided during treatment; and displaying a colored, outlined, or textured image of the identified healthy region to be avoided; and providing a treatment catheter comprising a catheter tip, wherein operation of a treatment catheter tip power source is inhibited when the catheter tip is within an operator-selectable distance from the identified healthy region to be avoided. - View Dependent Claims (15, 16, 17, 18, 19)
