摘要： A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

摘要： High resolution time sequences of 3D images that show the dynamics of a time varying changes are provided. The 3D time series of images representing an object that include time varying changes may be produced from lower dimensional image time sequences, such as 2D images. The 2D images may be generated using angiography and may include fluid flow information (e.g., arrival times). The fluid flow information may be provided, for example, by injecting a chemical into the fluid and analyzing its position in the object or body over time. A varying contrast model may be applied to determine the location of the chemical at different points in time which may assist in detecting an ailment.

摘要： 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.
