    Abstract: A tracking system for ultrasound imaging includes an imaging probe which acquires ultrasound image information including a plurality of ultrasound image frames; an inertial measurement unit coupled to the imaging probe and which synchronously acquires tracking information including a plurality of tracking frames indicative of motion of the imaging probe; and a controller. The controller is configured to obtain the ultrasound image information for at least two of the plurality of ultrasound image frames from the plurality of ultrasound imaging frames, and determine a similarity value based upon a comparison of the at least two ultrasound image frames. The controller is configured to compute whether the similarity value (Cframe) is less than a similarity threshold value (Cthresh), and select first or second pose estimation methods, each different from each other, based upon results of the computation of whether the similarity value (Cframe) is less than the similarity threshold value (Cthresh).

    Abstract: A system for selecting a calibration includes a data structure (138) including non-transitory computer readable storage media having a plurality of calibration entries stored therein and indexed to position and/or orientation criteria for a field generator. The field generator is configured for placement in an environment for sensor tracking. A calibration selection module (140) is configured to determine a position and/or orientation of the field generator and, based on the position and/or orientation, determine, using the data structure, corresponding calibration information stored in the data structure. The calibration information is optimized based upon the position and/or orientation of the field generator.

    Abstract: The generation of a pattern and for an adaptation to the specific geometry requires a lot of manual work. The workflow for the clinician is simplified during treatment planning. A treatment planning system is configured for determining a set of catheter or needle insertion positions to be used during treatment. The treatment planning system includes an image providing module for providing a medical image from which at least one treatment target structure can be derived. Further the treatment planning system includes a pattern providing module for providing one or a set of standard patterns for catheter or needle insertion including a plurality of catheter or needle insertion positions. The catheter or needle positions relate to treatment positions in the at least one treatment target structure.

    Abstract: A system for registration feedback includes a segmentation module (148) configured to segment a relevant three-dimensional structure in a first image to be registered and to segment a same relevant structure in a second image to be registered to provide three-dimensional segmentations of the first and second images. A registration module (152) is configured to register the three-dimensional segmentations of the first and second images by applying a registration transformation to one of the three-dimensional segmentations to map one three-dimensional segmentation onto the coordinate space of the other. A display (118) is configured to jointly display the three-dimensional segmentations of the first and second images, each of the three-dimensional segmentations having a different visual characteristic to permit identification of each of the three-dimensional segmentations in a joint display image such that registration between the three-dimensional segmentations in the joint display image provides an immediate indication of registration quality to a user.

    Abstract: A system for fusing images to account for motion compensation includes an imaging modality (110) configured to obtain a baseline image and current images. A live tracking system (115) is configured to track an imaging instrument for capturing the baseline image and the current images, the live tracking system having a coordinate system registered with the baseline image and the current images. A pose analyzer unit (132) is configured to employ field of view differences between a pose for the baseline image and a pose for a current view image using the live tracking system to generate success parameters. The success parameters are conveyed to provide feedback on image acquisition for motion compensation between the baseline image and the current view image.

    Abstract: Image co-registration (S390) entails: emitting energy, and responsively and dynamically acquiring images (216), the acquired images having a given dimensionality; selecting, repeatedly, and dynamically with the acquiring, from among the acquired images and, as a result of the selecting, changing, repeatedly, and dynamically, membership in a set (226) of images of the given dimensionality; and, synchronously with the change (S376), dynamically and iteratively registering the set to an image having a dimensionality higher than the given dimensionality. The co-registration is realizable with an imaging probe (140) for the acquiring, and a tracking system for tracking a location, and orientation, of the probe, the registering being specialized for the acquiring with the probe being dynamically, during the acquiring, any one or more of angulated, rotated and translated. The registering is initialized by individual transformations (220) of members of the set, but without need for reconstruction, of the set into an image of dimensionality higher than the given dimensionality, that derives, from the set, additional pixels (219) external to the members.
