CREATING A RESULTANT IMAGE FOR A SPECIFIABLE, VIRTUAL X-RAY QUANTA ENERGY DISTRIBUTION

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.

1. A method for creating a resultant image of a patient with an x-ray imaging device for a specifiable, virtual x-ray quanta energy distribution, the method comprising:
capturing a first image dataset of the patient, the first image dataset representing a first x-ray attenuation distribution of the patient in accordance with a first x-ray quanta energy distribution; capturing at least one second image dataset of the patient, the at least one second image dataset representing at least one second x-ray attenuation distribution of the patient corresponding to at least one second x-ray quanta energy distribution; specifying a virtual x-ray quanta energy distribution; 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; 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, wherein the third image dataset represents a third x-ray attenuation distribution of the patient corresponding to the specified virtual x-ray quanta energy distribution; and creating the resultant image from the third image dataset.
