Abstract: A system includes an imaging system and a tracking system. The system generates a navigation space based on one or more tracking signals emitted by a transmission device. The system generates a virtual space including at least a portion of a calibration phantom based on one or more images generated by the imaging system. The system identifies a set of coordinates in the virtual space in response to an event in which at least a portion of the tracked device is detected in the one or more images. The system calibrates a first coordinate system associated with the virtual space with respect to a second coordinate system associated with the navigation space in response to the event. Calibrating the first coordinate system with respect to the second coordinate system is based on the set of coordinates and temporal information associated with the event.

Abstract: Systems and methods for determining one or more phases of anatomical movement are provided. A catheter positioned in an anatomical element may be tracked using a tracker configured to track a pose of the catheter. Sensor data corresponding to a plurality of pose information of the catheter may be received from the tracker. One or more phases of motion of the anatomical element may be determined based on the plurality of pose information. An image may be received at a target phase of the one or more phases.

Abstract: A device and method are described for transmitting tissue conductance communication (TCC) signals. A device may be is configured to establish a transmission window by transmitting a TCC test signal at multiple time points over a transmission test period to a receiving device and detect at least one response to the transmitted TCC test signals performed by the receiving device. The IMD is configured to establish the transmission window based on the at least one detected response so that the transmission window is correlated to a time of relative increased transimpedance between a transmitting electrode vector and receiving electrode vector during the transmission test period.

Abstract: Methods and related systems and devices for cardiac therapy use pseudo-electric vectors (PEVs) for characterizing and representing the electrical forces generated by a patient's heart in a three-dimensional (3D) manner. PEVs may be used to predict whether a patient will respond to pacing therapy prior to implant, during implant, or in the follow-up after implant. Various cardiac therapy systems and devices, such as an electrocardiogram (ECG) belt or vest, which may include a plurality of external electrodes, may be used to obtain electrical activity information to generate the PEVs. One or more spatio-temporal PEVs may be determined using one or more sensors at one or more points in time. Spatial representation data may be determined based on the PEVs.

Abstract: The exemplary systems and methods may be configured to monitor electrical activity from a patient using a plurality of external electrodes. The exemplary systems and methods may be further configured to provide a model heart representative of the patient's heart based on at least one of a plurality of patient characteristics. The model heart can include a plurality of segments. The exemplary systems and methods may be further configured to determine a value of electrical activity for each of a plurality of anatomic regions of the model heart based on the mapped electrical activity. Each of the plurality of anatomic regions can include a subset of the plurality of segments.
