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.

Abstract: In a method for correctly geometrically assigning x-ray images of a patient an optically operating recording device is attached to an x-ray device generating the x-ray images. A dimensionally stable marker surface which can be optically detected by the recording device and defines a reference system is fixed to the patient in a fixed relative position. The x-ray device is brought into a first and second recording position such that the recording device is directed toward the marker surface. In a recording position the x-ray device produces a first and second x-ray image of the patient and the recording device produces a first and second recording of the marker surface. The respective geometric position of the first and second x-ray image is determined in the reference system from the recordings. The first and second x-ray images are correctly geometrically assigned to one another in accordance with their position.

Abstract: In a method for geometrically correct association of at least two 3D image data of a patient, a marker field that defines a reference and is dimensionally stable and can be imaged in an x-ray image, is fixed in a stationary position relative to the patient. An x-ray apparatus is brought into first and second 3D acquisition positions. In each of the 3D acquisition positions, the x-ray apparatus acquires first 2D x-ray images for the associated 3D image data in various positions. The first and second 3D acquisition positions are selected such that a second 2D x-ray image that includes an image of at least a portion of the marker field is acquired in at least one respective position. The respective attitudes of the 3D acquisition position and the 3D image data in the reference system are determined from the image of the marker field in the second 2D x-ray image. First and second image data are geometrically correctly associated with one another according to their respective attitude.

Abstract: Three-dimensional image information is generated of a body part that is larger than the visual field of an X-ray machine. An X-ray source and an X-ray detector are disposed at a first position such that the X-ray source and the X-ray detector can record a first projection image of at least a first section of a body part. Then the first projection image is recorded. The X-ray source and the X-ray detector are next disposed at a second position such that the X-ray source and the X-ray detector can record a second projection image of at least a second section of the body part. The second section partially overlaps the first section. The first and second projection images are merged to form a projected image. A three-dimensional volume of the body part is reconstructed from the plurality of projection images.

Abstract: Disclosed herein is a framework for facilitating fused-image visualization for surgery evaluation. In accordance with one aspect of the framework, at least one pre-operative image and at least one intra-operative image of an anatomical structure are received. A region of interest may be identified in the intra-operative image. The pre-operative image may be straightened, and a symmetric region may be identified in the straightened pre-operative image. The symmetric region is substantially symmetrical to a target region in the straightened pre-operative region. The target region corresponds to the region of interest in the intra-operative image. The symmetric region may be extracted and reflected to generate a reference image. The intra-operative image may be rigidly registered with the reference image to generate registered intra-operative image, which is overlaid on the target region in the straightened pre-operative image to generate a fused image.
