Abstract
Abstract An X-ray diagnostic apparatus has at least one radiation transmitter and at least one radiation receiver arranged spaced therefrom and an examination subject support plate. The radiation receiver is fashioned as a matrix detector and extends over the entire area of the examination subject support plate. Such an X-ray diagnostics apparatus is simply constructed in terms of structure and supplies high-contrast X-ray exposures in a short time and with low radiation exposure.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
65 words
An X-ray diagnostic apparatus comprising: a radiation transmitter; a radiation receiver disposed a distance from said radiation transmitter; an examination subject support plate disposed between said radiation transmitter and said radiation receiver; and said radiation receiver comprising a matrix detector which generates image signals which, in combination, form an image of an examination subject, said matrix detector being co-extensive in area with said support plate.
Claim 2
Dependent Claim
65 words
An X-ray diagnostic apparatus comprising: a radiation transmitter; a radiation receiver disposed a distance from said radiation transmitter; an examination subject support plate disposed between said radiation transmitter and said radiation receiver; and said radiation receiver comprising a matrix detector which generates image signals which, in combination, form an image of an examination subject, said matrix detector being co-extensive in area with said support plate.
Claim 3
Dependent Claim
38 words
