Abstract
Devices, systems, and methods of the present disclosure are directed to generating three-dimensional surface representations of an anatomic structure such as a heart cavity. More specifically, a three-dimensional surface representation of the anatomic structure is constrained relative to one or more anchor portions corresponding to received input regarding the location of anatomic features of the anatomic structure. The resulting three-dimensional surface representation includes salient features of the anatomic structure and, therefore, can be useful as visualization tool during any of various different medical procedures, including, for example, cardiac ablation.
Claims20
A method comprising:
- receiving a plurality of location signals, each received location signal indicative of a respective location of a medical device in an anatomic structure of a patient;
- forming a three-dimensional data structure representing volumes, within the anatomic structure, visited by the medical device at the locations corresponding to the plurality of location signals;
- receiving one or more anchor portions representing a subset of the three-dimensional data structure;
- generating a three-dimensional surface representation of the anatomic structure of the patient based on the plurality of location signals and the one or more anchor portions, the three-dimensional surface representation of the anatomic structure of the patient constrained relative to the one or more anchor portions and containing at least a portion of the three-dimensional data structure;
- and
- displaying, on a graphical user interface, a two-dimensional projection of the three-dimensional data structure, at least one of the one or more anchor portions, and/or a two-dimensional projection of the three-dimensional surface representation.
A system, comprising:
- one or more processors;
- and
- one or more non-transitory machine-readable media having stored thereon computer-executable instructions for causing the one or more processors to at least:
- receive a plurality of location signals, each received location signal indicative of a respective location of a medical device in an anatomic structure of a patient;
- form a three-dimensional data structure representing volumes, within the anatomic structure, visited by the medical device at the locations corresponding to the plurality of location signals;
- receive one or more anchor portions representing a subset of the three-dimensional data structure;
- generate a three-dimensional surface representation of the anatomic structure of the patient based on the plurality of location signals and the one or more anchor portions, the three-dimensional surface representation constrained relative to the one or more anchor portions and containing at least a portion of the three-dimensional data structure;
- and
- display, on a graphical user interface, a two-dimensional projection of the three-dimensional data structure, at least one of the one or more anchor portions, and/or a two-dimensional projection of the three-dimensional surface representation.
