摘要： A control device pivots an X-ray arrangement repeatedly between two final angular positions about a pivot axis. Projections of an object arranged in the region of the pivot axis and moving iteratively are detected at a plurality of angular positions and supplied to the control device. The control device also receives a phase position referring to the object and assigns the phase position to each projection. A computer selects one or more projections whose phase position corresponds at least approximately to a reconstruction phase position. If the computer has selected one projection for an angular position, it determines this projection as a reconstruction projection. If the computer has selected a plurality of projections for an angular position, it detects the reconstruction projection using these projections. The computer then detects a three-dimensional reconstruction of the object based on the reconstruction projection.

摘要： In addition to a radiation source (6) attached to a C-arm 4, and in addition to a detector (7), a rotation angiography device (1) for the angiocardiography has an evaluation unit (8), which formulates models with low resolution from the projection images supplied by the detector (7) for the moving object to be examined, and which generates movement fields for the projection images generated by the detector (7) on the basis of the model, so that movement-corrected projection images can be calculated from the projection images, which can be used to formulate a three-dimensional high-resolution model of the object to be examined.

摘要： With a method for generating an x-ray image sequence for supporting an intervention on a patient with a catheter or guide wire for instance, automatic recognition of the catheter is carried out with recorded x-ray images using a computer system. The x-ray image recording parameters are changed on the basis of the determined quality of the imaging of the object, with the x-ray device preferably being automatically activated with the changed x-ray image recording parameters, to record x-ray images. The doctor can therefore concentrate on the actual intervention and does not have to worry about operating the x-ray device.

摘要： A data processing system and method for multi-modal viewing of medical image visualization is described. The system includes an image display device operable to display an on-the-fly (“fly”) visualization of a three dimensional (3D) data set, and a live X-ray image, where the parameters of the “fly” visualization are adjusted so that the “fly” visualization image has a correspondence to the live X-ray image. The method includes recording a three dimensional (3D) data set, and a corresponding live X-ray image; rendering a “fly” visualization of the 3D data set; adjusting the attributes of the “fly” visualization to achieve a correspondence with the live X-ray image; and, simultaneously displaying the “fly” visualization image and the live X-ray image.
