Method and system unit for stereoscopic x-ray imaging

摘要

A method for stereoscopic x-ray imaging by a stereoscopic x-ray tube and by an x-ray radiation detector is provided. The x-ray radiation detector has a buffer. The stereoscopic x-ray tube has two x-ray beam sources disposed a short distance from one another. 2D image datasets are acquired at relatively short intervals one after the other, which have good quality.

1. A method for stereoscopic x-ray imaging by a stereoscopic x-ray tube comprising a first and a second x-ray beam sources and by an x-ray radiation detector, comprising:
disposing the first and the second x-ray beam sources at a distance from one another; converting x-ray beam quanta striking the x-ray radiation detector by a scintillator disposed on the x-ray radiation detector; arranging a grid of detector units on the x-ray radiation detector, each detector unit having a light-sensitive receiver at which a measurement value is changed by light quanta striking the light-sensitive receiver, and each detector unit having a buffer for the measurement value read out from the light-sensitive receiver; the method further comprising steps of:
resetting measurement values in light-sensitive receivers to a predefined value;emitting a first x-ray radiation from the first x-ray beam source passing through an image object before striking the x-ray radiation detector;reading the measurement values out from the light-sensitive receivers into associated buffers;resetting the measurement values in the light-sensitive receivers to the predefined value; emitting a second x-ray radiation from the second x-ray beam source passing through the image object before striking the x-ray radiation detector;
reading the measurement values out from the buffers into a central memory;generating a first x-ray image dataset from a projection direction of the first x-ray beam source;reading the measurement values out from the light-sensitive receivers into the central memory; andgenerating a second x-ray image dataset from a projection direction of the second x-ray beam source.
