Patent ID: 7583783

Claim:
An x-ray computer tomograph, comprising: an x-ray source configured to generate a fan beam of x-ray radiation; a detector array, wherein each of the x-ray source and the detector array is situated on opposite sides of a gantry so that the x-ray radiation passes completely through a test region; a row of detector elements situated in a plane of the fan beam and adjoined in at least one direction perpendicular to the fan beam by several additional rows of detector elements; wherein during a measurement, no secondary collimator is positioned between the test region and the detector array, wherein a width of each of the detector elements is less than or equal to 0.5*β*Z P , where β is twice the angle of spread of the x radiation and Z P is the distance of the measurement point from the detector array, and wherein a height (h) of each of the detector elements corresponds to the equation: h≦ 0.2*arc sin( q *λ)* Z P , where q is a pulse transmission, λ is a wavelength of the x-ray radiation, and a pulse transmission spectrum lies between 0.2 and 2 nm −1 .
