Abstract
A radioscopy device is provided. The radioscopy device includes a detector grid; and a scattered radiation matrix. The detector grid is disposed relative to the scattered radiation matrix, which is substantially perpendicular to a direction in which the integral across both location-frequency coordinates of the Fourier transforms of the detector grid and the scattered radiation matrix is at a minimum.

A radioscopy device, comprising:
- a detector grid;
- and
- a scattered radiation matrix,
- wherein the detector grid is disposed relative to the scattered radiation matrix substantially perpendicular to a direction in which an integral across both location-frequency coordinates of Fourier transforms of the detector grid and the scattered radiation matrix is substantially at a minimum.
A method for adapting a detector grid and a scattered radiation matrix of a radioscopy device to one another, the method comprising:
- forming a two-dimensional Fourier transform for the detector grid;
- forming a two-dimensional Fourier transform for the scattered radiation matrix;
- forming a product of the Fourier transforms;
- forming an integral across both location-frequency coordinates of the product;
- and
- rotating the detector grid and the scattered radiation matrix relative to one another, so that the detector grid and the scattered radiation matrix are disposed relative to one another in such a way that the integral substantially produces a minimum.
A medical examination device for examining an object, comprising:
- an X-ray source;
- a detector grid;
- and
- a scattered radiation matrix,
- wherein the detector grid is disposed relative to the scattered radiation matrix substantially perpendicular to a direction in which an integral across both location-frequency coordinates of Fourier transforms of the detector grid and the scattered radiation matrix is at a minimum, and
- wherein the object is disposed between the X-ray source and the scattered radiation matrix.
