Abstract
A method and an X-ray device are disclosed for creating an X-ray projection image of a three-dimensional object under examination and for displaying the projection image. In at least one embodiment, pixel images are recorded from two different perspectives and a projection image is created by overlaying the two pixel images, wherein perspective-related offset of the mapping image pixels is taken into account, pixel-by-pixel, in relation to an imaging surface in the object under examination.
Claims18
A method for creating a projection image of a three-dimensional object under examination, comprising:
- recording pixel images from two different perspectives;
- and
- creating the projection image by overlaying the pixel images, a perspective-related offset of the imaging pixels being taken into account, pixel-by-pixel, in relation to an imaging surface in the three-dimensional object under examination.
An X-ray device for creating an X-ray projection image of a three-dimensional object under examination, comprising:
- at least one X-ray tube for radioscopy of the object under examination by X-rays from at least two focus positions and creation of at least two pixel images;
- a programmable control and processing unit including a memory for storing program code which is executed during operation, the program code stored in the memory, when executed during operation of the X-ray device, causing the programmable control and processing unit to
- record pixel images from two different perspectives, and
- create the X-ray projection image by overlaying the pixel images, a perspective-related offset of the imaging pixels being taken into account, pixel-by-pixel, in relation to an imaging surface in the three-dimensional object under examination.
