摘要： A method for creating a resultant image for a specifiable, virtual x-ray quanta energy distribution includes capturing a first image dataset of the patient, capturing at least one second image dataset of the patient, and specifying a virtual x-ray quanta energy distribution. The method also includes establishing a spatial density distribution of the patient for at least two materials based on the first image dataset and the at least one second image dataset. The method includes creating a third image dataset of the patient based on the specified virtual x-ray quanta energy distribution and the established spatial material density distributions. The third image dataset represents an x-ray attenuation distribution of the patient corresponding to the specified virtual x-ray quanta energy distribution. The method also includes creating the virtual image from the third image dataset.

摘要： A method is disclosed for reconstructing image data of an object under examination from measured data, with the measured data having been detected beforehand during a relative rotational movement between a radiation source of a computer tomography system and the object under examination. In at least one embodiment, a radiation scatter correction variable is determined, which is subjected to a low pass filtering. The filtered radiation scatter correction variable is connected with the measured data to correct the measured data, and image data is reconstructed from the measured data thus corrected.

摘要： A method is for producing CT images of at least one second organ cyclically excited to move by a first organ moving on its own, or examination area with rest phases and activity phases of a patient. The second organ or the examination area is scanned, preferably spirally. A three-dimensional image of the absorption coefficient is determined with the aid of a multiplicity of cutting planes on the basis of the data obtained by scanning in the rest phase of the second organ or examination area, and the movement information required to determine the rest phase is collected from the first organ.
