  • Patent number: 9427286
    Abstract: A method, an imaging apparatus and a computer readable medium are enabled for automatically registering medical images. The imaging apparatus may be an amended C-arm. The image acquisition apparatus has a primary x-ray source and at least one auxiliary x-ray source, a detector for receiving radiation of the primary and auxiliary x-ray source, and an interface to a registration unit. The registration unit computes a 3D/2D registration of a provided 3D image and at least two acquired 2D images. An output interface is configured to provide an output and to display the registered images on a monitor.

  • Patent number: 9165362
    Abstract: A method of 3D-2D registration for medical imaging includes the following steps: providing a first input interface for acquiring a three-dimensional image; providing a second input interface for acquiring a fixed two-dimensional image using an imaging system that includes a source and a detector and that has an unknown source-detector geometry; initializing image transformation parameters and source-detector geometry parameters; generating a reconstructed two-dimensional image from the three-dimensional image using the image transformation parameters and the source-detector geometry parameters; determining an image similarity metric between the fixed two-dimensional image and the reconstructed two-dimensional image; and updating the image transformation parameters and the source-detector geometry parameters using the image similarity metric, and a corresponding non-transitory computer-readable medium and apparatus.

  • Publication number: 20150125033
    Abstract: A method of determining bone fragment navigation may include receiving pre-operative 2D image data of a reference bone structure and a bone fragment. The reference bone structure may include a first set of fiducial markers provided thereon, and the bone fragment may include a second set of fiducial markers provided thereon. The method may further include performing a 2D-3D registration between the pre-operative 2D image data and a 3D model of the reference bone structure and the bone fragment, after manual repositioning of the bone fragment, receiving second 2D image data, performing 2D-2D registration of the first set of fiducial markers and the second set of fiducial markers between the pre-operative 2D image data and the second 2D image data, and determining 3D movement of the bone fragment based at least in part on the 2D-2D registration.

  • Publication number: 20140049629
    Abstract: A tracking and navigation system is provided. The system includes an imaging or treatment device, a tracker device, and a fiducial marker. At least part of the imaging or treatment device is movable relative to a patient. The tracker device is mounted on the imaging or treatment device and is movable therewith relative to the patient. The fiducial marker may be fixed relative to the patient to define a patient coordinate system. The fiducial marker is detectable by the tracker device to substantially maintain registration between the tracker device and the patient coordinate system.

  • Publication number: 20120289826
    Abstract: A method for localization and identification of a structure in a projection image with a system having a known system geometry, includes acquiring a preoperative computer-tomography or CT image of a structure, preprocessing the CT-image to a volume image, acquiring an intraoperative two dimensional or 2D X-ray image, preprocessing the 2D X-ray image to a fix image, estimating an approximate pose of the structure, calculating a digitally reconstructed radiograph or DRR using the volume image, the estimated pose and the system geometry, and calculating a correlation between the generated DRR and the fix image, with a correlation value representing matching between the generated DRR and the fix image. The method significantly decreases the number of wrong-level surgeries and is independent of the surgeon's ability to localize and/or identify a target level in a body.
