X-ray diagnostic apparatus with relatively moved x-ray source and detector
First Claim
Patent Images
1. An x-ray diagnostic apparatus comprising:
- positioning table adapted to receive a subject;
an x-ray source, which emits an x-ray beam, disposed at a first side of said positioning table;
a digital x-ray detector disposed on a second side of said positioning table, opposite said first side, so that said x-ray beam, after penetrating a subject, is incident on said digital x-ray detector, said digital x-ray detector comprising a plurality of imaging elements disposed in a matrix which emit output signals dependent on x-rays incident thereon;
a device for producing relative movement between said x-ray source and said digital x-ray detector along a movement direction;
a computerized imaging system supplied with said output signals from said digital x-ray detector for producing a plurality of digital images therefrom, and for superimposing said digital images to produce a superimposed image wherein details only within a specified longitudinal slice of said subject are sharply imaged; and
said x-ray detector being rotated at an angle relative to said movement direction.

Abstract
In an x-ray diagnostic apparatus for tomosynthesis or laminographic imaging using a patient positioning table, an x-ray source which emits an x-ray beam on one side of the patient positioning table, an x-ray detector arranged on the other side of the patient positioning table for the capture of the x-ray beam and for producing digital images, a device for movement of the x-ray source, a device for shifting of the x-ray detector and a device for superimposing the digital images so that only the details lying in a specific longitudinal slice for an examination subject are sharply imaged, the x-ray detector is rotated relative to the movement direction at an angle.
