Abstract: The pose of an implant represented in a medical image is determined from the medical image. The x-ray image of the implant is compared to a database of the implant viewed at different poses (e.g., viewed from different directions). The implant pose associated with the best match indicates the pose of the implant in the x-ray image.

Abstract: In an imaging system and method for preparing x-ray images and optical images, at least two x-ray images of an examination subject are acquired by emitting x-rays from at least two different x-ray image acquisition points in space. At least two optical exposures are acquired from the examination subject at respective optical exposure origination points that respectively optically correspond to the x-ray image acquisition points. The optical exposures and the x-ray images are superimposed so that each optical image is superimposed with the x-ray image that originated from an x-ray image origination point corresponding to the optical exposure origination point of that optical exposure.

Abstract: A nuclear magnetic resonance apparatus for the examination of a subject has coils for respectively generating fundamental and gradient magnetic fields in which the examination subject is disposed, and a radio-frequency measurement unit which irradiates the examination subject with a sequence of radio-frequency pulses and which acquires the nuclear magnetic resonance signals emitted from the examination subject. The pulse sequences generated by the radio-frequency measurement unit are selected such that information for two differently emphasized spin-echo images and information for a T.sub.1 -emphasized image from a stimulated echo are acquired in one sequence.

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.

Abstract: The device enables the detection of positions of the navigation marking elements on a reference star by way of at least two projection images taken by an X-ray system at different pivoting angles of a C-arm. The positions of the navigation marking elements on the reference star are also calculated by a navigation system tracking camera. The transformation from the coordinate system of the navigation system into the coordinate system of the X-ray system is calculated from the position of the reference star detected by the X-ray system and the position of the reference star detected by the tracking camera. The navigation marking elements are located outside of the volume which is reconstructed by way of the imaging process in order to prepare tomographic images. The positions of the navigation marking elements are determined from two-dimensional projections. All the navigation marking elements need only be detected by at least two projection images.
