Abstract: An acoustic probe connectable to an imaging system. The acoustic probe has a substrate with first and second principal surfaces, at least one device insertion port comprising an opening passing through the substrate from the first principal surface to the second principal surface, and an array of acoustic transducer elements supported by the substrate and disposed around the at least one device insertion port. The acoustic probe comprising an instrument guide disposed within the device insertion port, the instrument guide being configured to selectively allow the interventional device to move freely within the device insertion port and to selectively lock the interventional device within the device insertion port in response to a user input via a user interface connected to the acoustic probe.

Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

Abstract: A system for registration feedback includes a segmentation module 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 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 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: An intervention system employs an interventional device (10), and a sensor wire (20) manually translatable within a lumen (11). The intervention system further employs a reconstruction controller (44) for reconstructing a shape of the interventional tool (10) responsive to a sensing of a manual translation of the sensor wire (20) within the lumen (11) (e.g., a EM sensor being attached to/embedded within a guide wire), and for determining a reconstruction accuracy of a translation velocity of the sensor wire (20) within the lumen (11) to thereby facilitate an accurate reconstruction of the shape of the interventional tool (10). The reconstruction accuracy may be determined by the reconstruction controller (44) as an acceptable translation velocity being less than an acceptable threshold, an unacceptable translation velocity being greater than an unacceptable threshold, and/or a borderline translation velocity being greater than the acceptable threshold and less than the unacceptable threshold. The reconstruction controller (44) generates an acceptability indicator that may be visualizing or audibly communicated via a user interface (48).

Abstract: A system (100) for tracking the position and orientation (i.e., the pose) of a medical imaging device (210) is described. The system determines in real time the pose of an imaging medical device based on a combination of image data and sensor data obtained from an imaging medical device and tracking sensors (210) associated with the device. Pose is determined based on a calculated tracking pose change and a calculated image pose change and a determined reliability of the calculated tracking pose change and the calculated image pose change.

Abstract: An electromagnetic field quality assurance system employing an electromagnetic field generator (10) for emitting an electromagnetic field (12), and one or more quality assurance electromagnetic sensors (11, 21, 31, 41, 50) for sensing the emission of the electromagnetic field (12). The system further employs a quality assurance controller (74) for assessing a tracking quality of the electromagnetic field (12) derived from a monitoring of a sensed position of each quality assurance electromagnetic sensor (11, 21, 31, 41, 50) within a field-of-view of the electromagnetic field (12). The electromagnetic field generator (10), an ultrasound probe (20), an ultrasound stepper (30) and/or a patient table (40) may be equipped with the quality assurance electromagnetic sensor(s) (11, 21, 31, 41, 50).

Abstract: A system for ablation planning and treatment includes a delineation module (124) configured to distinguish tissue types in an image, the tissue types including at least a core tissue and a margin zone encapsulating the core tissue. A treatment planning module (140) is configured to apply weightings in a cost function to prioritize ablation coverage of the tissue types including the core tissue and the margin zone to determine ablation characteristics that achieve an ablation composite in accordance with user preferences. A graphical user interface (122) is rendered on a display to indicate the core tissue, the margin zone, the ablation composite and permit module user selection of one or more treatment methods.

Abstract: A brachytherapy seed localization system for localizing radioactive seeds within a diseased tissue, the brachytherapy seed localization system employs a tool tracking machine (50) for generating a tracked seed distribution map (51) of delivered locations of the radioactive seeds within the diseased tissue, and a tissue imaging machine (60) for generating a seed distribution image (61) of projected locations of the radioactive seeds within the diseased tissue including at least one false projected location. The brachytherapy seed localization system further employs a brachytherapy seed localizer (70) for generating a composite seed distribution map (71) of estimated locations of the radioactive seeds within the diseased tissue derived from a combination of the tracked seed distribution map (51) and the seed distribution image (61) excluding any false projected location(s) within the seed distribution image (61).

Abstract: An interventional therapy system may include at least one controller which may obtain a reference image dataset of an object of interest (OOI); segment the reference image dataset to determine peripheral outlines of the OOI in the plurality image slices; acquire a current image of the OOI using an ultrasound probe; select a peripheral outline of a selected image slice of the plurality of slices of the reference image dataset which is determined to correspond to the current image; and/or modify the selected peripheral outline of the image slice of the plurality of slices of the reference image dataset in accordance with at least one deformation vector.

Abstract: The invention relates to a determination apparatus for determining the pose and shape of an introduction element like a catheter within a living being, wherein the introduction element is adapted to be used by a brachytherapy apparatus for introducing a radiation source close to a target object to be treated. A position determination element like guidewire with an electromagnetic tracking element is introduced into the introduction element such that it is arranged at different locations within the introduction element, wherein the positions of the position determination element within the introduction element are determined. The determined positions are then acquired depending on the determined positions for determining the pose and shape of the introduction element within the living being. This can lead to a determination procedure with reduced user interaction, thereby simplifying the determination procedure for the user.
