METHOD AND DEVICE FOR DISPLAYING AN OBJECT WITH THE AID OF X-RAYS

摘要

A method and a device for displaying an object with the aid of X-rays include recording a multiplicity of X-ray projections from which a volume data set characterizing the density of the object is reconstructed. Subsequently, density values along a ray are determined on the basis of the volume data set. By carrying out low pass filtering for the density values along the ray, and determining the maximum of the filtered density values (maxima of the filtered density values), values are obtained for displaying the object which simultaneously effectively image fine structures and are scarcely subject to the influence of artifacts.

1. A method for displaying an object with the aid of X-rays, the method comprising the following steps:
a) recording a multiplicity of X-ray projections; b) reconstructing a volume data set characterizing a density of the object; c) determining density values along a ray based on the volume data set; d) carrying out low pass filtering for the density values along the ray; e) determining a maximum of the filtered density values; and f) displaying the object using the maximum of the filtered density values.
