Abstract: A medical system may be configured to determine, at least in response to a selection or activation of a first transducer set, a second transducer set satisfying a determined positional relationship with respect to the first transducer set, each transducer in the second transducer set configured to record a respective electrogram, and the second transducer set mutually exclusive with the first transducer set. The medical system may be configured to visually display or increase a visual prominence of a portion of an electrogram set derived from or corresponding to the determined second transducer set.

Abstract: A graphical representation may include a representation of a bodily cavity and graphical elements corresponding to transducers positionable in the bodily cavity. User input may be received indicating an encircling path around at least a region of the representation of at least a portion of the bodily cavity. A first region of space may be determined as being in a determined positional relationship with respect to the encircling path, the determined positional relationship being interior or exterior of the encircling path. A machine-based selection of a first transducer set may be made, the machine-based selection selecting each transducer in the first transducer set as having at least part of a corresponding graphical element in the determined first region of space. Each transducer in the first transducer set may be activated.

Abstract: At least a first transducer set of a transducer-based device may be activated to deliver a first high voltage pulse set to cause pulsed field ablation of tissue. A data set may be monitored, the data set indicative of separation between a second transducer set of the transducer-based device and a tissue surface in a bodily cavity. Depending on a degree of separation, indicated by the data set, between the second transducer set and the tissue surface, a quality of a lesion producible in the tissue by the first high voltage pulse set may be determined. At least in response to the determination of the quality of the lesion producible in the tissue by the first high voltage pulse set, display of a graphical element set may be caused to indicate the determined quality of the lesion.

Abstract: Computing devices and methods are provided to automatically characterize a localization system tracker for a procedure. A starting tracker definition is refined until convergence using an iterative process and measured features of the tracker in images provided by a localization system camera. In each iteration, poses are determined from the measured features using a current tracker definition. The current definition is then refined using the poses and an optimization function. Tracker images may be captured passively, when performing other procedure steps. In a robotic context, command trajectories move a robot may be to respective poses where images to characterize the tracker are captured. An updated trajectory may be commanded to optimize convergence, additionally using the measured features at the updated pose in the iterative process. A robot kinematic model may be defined, refining a starting model using tracker poses from the localization system and sensor positions from the robot system.

Abstract: An electrophysiological information processing system may be configured to acquire electrophysiological information indicating sensed electrophysiological activity produced within a patient body, the electrophysiological activity sensed via at least a first transducer. Temperature information may be received indicating temperature at least proximate the first transducer. The electrophysiological information may be modified in accordance with the received temperature information, and the modified electrophysiological information may be output.

Abstract: A tissue ablation system may be configured to receive location information indicating locations of at least part of a transducer-based device in a bodily cavity; cause delivery of first tissue-ablative energy during a duration of a first particular time period in accordance with a first energy waveform parameter set at least in response to a first state in which at least part of the location information indicates at least a first rate of movement of the part of the transducer-based device in the bodily cavity; and cause delivery of second tissue-ablative energy during a duration of a second particular time period in accordance with a second energy waveform parameter set at least in response to a second state in which the at least part of the location information indicates at least a second rate of movement of the part of the transducer-based device in the bodily cavity.

Abstract: There are provided systems and methods for the safe transfer and verification of sensitive data. Personally identifying information from the sensitive data for an individual is encoded using mapping (e.g. hashing) to have statistical characteristics that limit the encoded information from being considered statistically identifiable. Identical, non-unique encoded output may be generated from multiple individuals from their respective unique personally identifying information. Determining the identity of a person using the encoded output (without any other identifying data) is statistically unlikely. The mapping may be configured such that all possible encoded output (e.g. each respective instance of output in the output space) have a statistically equal chance of being generated.

Abstract: Preoperative planning techniques are described such as for hip surgery. Rather than pre-operatively planning by reorienting a model of the boundaries of the acetabulum derived from a 3D medical image, the proposed solution reorients portions of the 3D medical image itself and simulates one or more x-ray images using the reoriented 3D data. Optionally, simulated x-ray(s) of the un-modified CT scan may also be generated for comparison purposes. The user then measures acetabular metrics on the simulated x-ray(s) in order to determine the radiographic outcomes that a given magnitude and direction of reorientation would achieve. By iteratively selecting a reorientation and measuring the simulated x-ray(s), an optimal reorientation plan is determined by the user.

Abstract: Systems, methods, etc. for collaboration enable receipt of an expert consultation providing a recommendation in a particular scenario. An example is a surgery consultation. Outcome monitoring may generate measures of outcomes to evaluate the recommendations. A predictive outcome expert system (e.g. a prognosis expert system for surgery) may be trained using the respective expert recommendations and the measures of outcomes to generate outcome predictions automatically. Such training data for the prognosis expert system may also comprise plan execution data (indicating how successfully the recommendation was actually achieved), post-procedure care data, etc. In an orthopedic context, planning data may be input to the prognosis expert system to evaluate a particular plan. The prognosis expert system may be utilized to optimize the plan responsive to the predicted outcomes.

Abstract: Preoperative planning of a procedure such as an orthopedic procedure is enabled to use first images of patient anatomy in a functional position to define a 3D model and a plan for the procedure and to export the plan to systems configured to use surface information derived from second images of the patient. First images may comprise X-rays including biplanar X-rays. Second images may comprise volumetric datasets such as CT scans. The plans and the surface information may be used together via relative to a common coordinate system. Systems configured to use surface information derived from CT scans, typically of patients in non-functional positions are thus enabled to use plans prepared from images of patients in functional positions such as from (synchronized) biplanar X-rays of patient anatomy.
