1. A computing system for visualizing a treatment device during a cardiac procedure, the system, comprising:
a communication interface that is communicatively coupled to a sensor configured to collect positional data and electrophysiological data within a cardiac anatomical structure;
a display;
a memory; and
one or more processors that are communicatively coupled to the communication interface and the memory, wherein the one or more processors are collectively configured to:
generate a graphical user interface comprising one or more topological maps constructed from a three-dimensional anatomical model of a portion of an anatomical feature, the three-dimensional anatomical model being constructed based on sensor data obtained from an intrabody device positioned within the anatomical feature, the sensor data comprising anatomical data and electrophysiological data collected during a medical procedure, wherein the one or more topological maps comprise at least one interior map view of the portion of the anatomical feature from a simulated viewpoint located within a lumen of the anatomical feature and corresponding to a position of the intrabody device; and
generate a device icon on each of the one or more topological maps, the device icon representing a real-time location and orientation of an ablating surface of the intrabody device within the anatomical feature, the device icon being rendered based on positional tracking data obtained from one or more sensors of the intrabody device.
