摘要： To allow safe treatment of a patient, in particular a puncture or biopsy using a needle, a 2D sectional image of an implant plane and a further 2D sectional image of an orthogonal plane are generated from a 3D image data record of a region to be examined. The two planes are hereby oriented such that the needle is on the one hand located within the implant plane and on the other hand is oriented in a perpendicular manner in respect of the orthogonal plane. The in particular parallel display of the 2D images allows the doctor to acquire the relative position of the needle in relation to the region to be examined in a simple and intuitive manner.

摘要： The invention relates to a method and an apparatus for reconstructing a three-dimensional image volume from two-dimensional projection images of a subject which have been taken from different projection directions by rotating the recording system around the subject, wherein the grayscale values of the voxels of the image volume are calculated by back projection of the projection images. The invention is characterized in that prior to back projection at least one projection image is modified in such a way that it corresponds to a projection image taken with a virtual detector whose axes are aligned parallel to the rotational axis of the recording system.

摘要： A method and an apparatus for generating an output image from a volume data set that includes a plurality of voxels are provided. In the method, a rendered 2D image is generated from the volume data set by volume rendering. In order to generate an output image with adjusted brightness, which makes a manual readjustment of the brightness superfluous, an adjustment factor is determined based on a brightness value of pixels in the rendered 2D image. By multiplying a respective voxel brightness value of the voxels in the volume data set by the adjustment factor, a brightness-adjusted volume data set is generated. By volume rendering from the brightness-adjusted volume data set, the brightness-adjusted output image is generated.

摘要： A method for determining a three-dimensional image dataset by an X-ray device is disclosed herein. The method includes recording projection images of an examination object from a plurality of recording angles, and reconstructing the image dataset from the projection images, wherein, for at least one examined projection image, in each case an interference condition is evaluated the fulfillment of which is dependent upon at least parts of the image data of the (respective) examined projection image and/or upon at least one parameter of the radiation source during the recording of the (respective) examined projection image and indicates that the (respective) examined projection image is a projection image with interference during the recording of which arcing has occurred in the radiation source. The method also includes disregarding at least one projection image with interference, or giving the projection image a lower weighting than all the projection images with no interference, or replacing the projection image with a synthetic projection image.
