Abstract
Systems and methods of automatically controlling, on a graphical user interface used by a physician, display views of an anatomic structure of a patient. Such systems and methods of automatically controlling display views of an anatomic structure of a patient can facilitate visualizing a position of a medical device relative to the anatomic structure during a medical procedure directed to the anatomic structure. In certain implementations, the systems and methods of the present disclosure provide automatic display views of a cardiac catheter relative to a three-dimensional model of a patient's heart cavity during a medical procedure such as cardiac ablation.
Claims21
A method comprising:
- obtaining a three-dimensional model of a heart cavity of a patient;
- receiving a signal indicative of a location of a catheter in the heart cavity of the patient;
- determining at least one geometric feature of the three-dimensional model;
- determining a display view of the three-dimensional model of the heart cavity based at least in part on the location of the catheter in the heart cavity, on one or more previous locations of the catheter in the heart cavity, and on the geometric feature of the three-dimensional model;
- and
- displaying, on a graphical user interface, the display view of the three-dimensional model of the heart cavity.
A method of controlling a display of a three-dimensional model of an anatomic structure of a patient, the method comprising:
- obtaining the three-dimensional model of the anatomic structure of the patient;
- receiving a signal indicative of a location of a medical device in the anatomic structure;
- based at least in part on the location of the medical device in the anatomic structure, selecting a display rule, from a plurality of rules, for specification of an orientation of the three-dimensional model and an image plane;
- based at least in part on the display rule, specifying i) the orientation of the three-dimensional model and ii) the image plane;
- and
- displaying, on a graphical user interface, at least a portion of a projection of the three-dimensional model, in the specified orientation, on the specified image plane.
