Abstract
During the generation of a panoramic x-ray recording, the use of semi-transparent x-ray screens allows the patient's x-ray exposure to be reduced when partial x-ray images are created, in spite of relatively large overlapping areas between the partial x-ray images.
Claims10
An x-ray device for generating panoramic x-ray images, comprising:
- an x-ray source configured to output an x-ray beam cone and a detector for creating partial x-ray images;
- said x-ray source having an x-ray screen unit with first and/or second semi-transparent collimators to be actuated for taking partial x-ray images of a panoramic x-ray image;
- said first and/or second semi-transparent collimators being disposed for movement into the x-ray beam cone of said x-ray source to thereby cause at least portions of respectively overlapping areas of the partial x-ray images to be joined to one another to be created with a reduced x-ray dose.
A method of generating x-ray recordings, the method comprising:
- outputting a beam cone with an x-ray source and detecting x-rays with a detector;
- creating partial x-ray images for a panoramic x-ray recording and thereby moving a first and/or second semi-transparent collimator into the x-ray beam cone issuing from the x-ray source such that at least parts of overlapping areas of the partial x-ray images to be joined to one another are created using a reduced x-ray dose.
