    摘要: A cardiac imaging system including an imaging module including an ultrasound emitter and one or more position markers. A tracking and control system may include a position sensing system for sensing a location and orientation of the position marker relative to a predetermined reference. The tracking and control system may be operable with the imaging module to produce at least a three dimensional image of a patient's anatomy. A method of cardiac imaging may include operatively attaching one or more position markers to an imaging module including an ultrasound emitter. The method may further include sensing a location and orientation of the position marker relative to a predetermined reference, and producing at least a three dimensional image of a patient's anatomy by evaluating one or more images obtained by the imaging module and aligning the image(s) obtained by the imaging module relative to the location and orientation of the position marker.

    摘要: In an electrophysiology (EP) lab, a bedside interface device allows an EP physician to directly control various diagnostic and therapeutic systems, including an electro-anatomic mapping system. The bedside interface device can include a computer with wireless communication capability as well as a touch-responsive display panel and voice recognition. The bedside interface device can also be a hand-graspable wireless remote control device that is configured to detect motions or gestures made with the remote control by the physician, allowing the physician to directly interact with the mapping system. The bedside interface device can also be a motion capture camera configured to determine motion patterns of the physician's arms, legs, trunk, face and the like, which are defined in advance to correspond to commands for the mapping system. The bedside interface device may also include voice recognition capabilities to allow a physician to directly issue verbal commands to the mapping system.

    摘要: A method of registering two or more localization systems utilizing unique coordinate frames A and B to a common coordinate frames includes measuring position information for one or more reference locations r in each coordinate frame (e.g., Ar and Br). For each reference location, a fiducial grouping is created from the respective position measurements (e.g., (Ar, Br)). The fiducial groupings are used to generate a mapping functionfthat transforms position measurements expressed relative to the second coordinate frame B to the first coordinate frame A. The mapping function f is defined such that a distance between f(Br) and Ar is about zero for each reference location r. Each localization system may also measure position information for a respective fixed reference localization element. Divergence between these fixed reference localization elements in the common coordinate system may be used to monitor, signal, and correct for anomalies such as dislodgement and drift.

    摘要: A method of modeling a surface from a plurality of geometry points representing an object generally includes binning the plurality of geometry points into an n-dimensional array of cells and associating a binary value with each cell; applying a dilation algorithm to the binned plurality of geometry points to output a dilated binary representation of the plurality of geometry points; applying an erosion algorithm to the dilated binary representation of the plurality of geometry points to output a segmented volume; and applying a surface construction algorithm to the segmented volume to form a surface model of the object.
