Abstract: A method includes, receiving from a calibration probe multiple data points acquired in an organ of a patient, each data point including (i) a respective position of the calibration probe, and (ii) a respective set of electrical values indicative of respective impedances between the position and multiple electrodes attached externally to the patient. A mapping between sets of the electrical values and respective positions in the organ is constructed, by performing for each received data point: if the mapping already contains one or more existing data points in a predefined vicinity of the data point, the one or more existing data points are adjusted responsively to the received data point, and if the predefined vicinity does not contain any existing data points, the received data point is added to the mapping. A position of a medical probe is subsequently tracked in the organ using the mapping.

Abstract: A method and system for assessing the effectiveness of a treatment regimen. In a preferred embodiment, baseline magnetic resonance imaging signals of a diseased portion of a subject's anatomy are acquired and image slices associated with diseased tissue or a selected region of interest are identified. The identified image slices are then stored and used in acquiring subsequent magnetic resonance imaging signals. The baseline and subsequently acquired magnetic resonance imaging signals are then processed to determine changes in location, size or other factors that provide an indication of whether treatment is effective. In another aspect, baseline and subsequent magnetic resonance parameters are also acquired and compared as part of determining the effective of treatment.

Abstract: Described here are systems and methods for estimating shear wave velocity from data acquired with a shear wave elastography system. More particularly, the systems and methods described here implement a spatiotemporal time-to-peak algorithm that searches for the times at which shear wave motion is at a maximum while also searching for the lateral locations at which shear wave motion is at a maximum. Motion can include displacement, velocity, or acceleration caused by propagating shear waves. A fitting procedure (e.g., a linear fit) is performed on a combined set of these temporal peaks and spatial peaks to estimate the shear wave velocity, from which mechanical properties can be computed. Motion amplitude thresholding can also be used to increase the number of points for the fitting.

Abstract: Methods and apparatus is provided for use in a medical procedure for image acquisition using a high-resolution imaging system, a three dimensional imaging system and a navigation system. A 3D imaging scan of an imaged portion of the surface of the patient is acquired using the three dimensional imaging system. Then, a first high-resolution imaging scan covering a first sub-portion of the imaged portion is acquired using the high-resolution imaging system, which is tracked by the navigation system. The 3D imaging scan and the first high-resolution imaging scan are combined to create an enhanced three dimensional image having contour lines to provide a visual representation of depth derived from depth information acquired from both the three dimensional imaging system and the high-resolution imaging system. Subsequent high resolution scans may then be stitched into the image and the updated image displayed in real-time.
