  • Patent number: 10022099
    Abstract: A change of X-ray radiation quality due to a material existing between an X-ray source and a detection element is estimated and corrected. Accordingly, deterioration of material discrimination ability in a dual energy imaging method can be prevented. An X-ray imaging apparatus is provided with an inherent filtration calculator configured to use measured data obtained by imaging air at two or more types of different tube voltages to calculate a deviation from a reference radiation quality, as a transmission length (inherent filtration) of a predetermined reference material. A reference-material transmission-length conversion is applied to the measured data according to the dual energy imaging method, thereby calculating the reference material transmission length (inherent filtration). When a subject is imaged, the dual energy imaging is performed by adding the inherent filtration calculated as to each detection element, and this produces an image with the change of radiation quality having been corrected.

A collimator (512) collimates the radiation, producing a radiation beam (516) that traverses a field of view (520) of the examination region and a subject or object therein. A detector array (522), located opposite the radiation source, across the examination region, detects radiation traversing the field of view and produces a signal indicative of the detected radiation. A beam shaper (524), located between the radiation source and the collimator, rotates in coordination with the focal spot and defines an intensity profile of the radiation beam. The beam shaper includes a plurality of elongate x-ray absorbing elements (606) arranged parallel to each other along a transverse direction with respect to a direction of the beam, separated from each other by a plurality of material free regions (604).

  • Patent number: 9545234
    Abstract: A method to optimally set a position of a form filter in an x-ray image recording apparatus is proposed. The x-ray image recording apparatus has an x-ray radiation source and an x-ray radiation detector. An x-ray image is firstly recorded in a first position of the form filter. A new position of the filter is then calculated and automatically set with the aid of the x-ray image. A new x-ray image is then recorded. With a minimal dose of a patient, the method enables low contrast images to be recorded for a minimal main dose of the patient, in particular in a sequence.

  • Patent number: 9535186
    Abstract: Among other things, computed tomography (CT) systems and/or techniques for generating projections images of an object(s) under examination via a CT system are provided. A surface about which the projection image is focused is defined and data yielded from vertical rays of radiation intersecting the surface and data yielded from non-vertical rays intersecting the surface are used to generate the projection image. In some embodiments, the projection image is assembled from one or more projection lines, which are respectively associated with a line-path contacting the surface and extend in a direction parallel to an axis of rotation for a radiation source. A projection line is indicative of a degree of attenuation experienced by rays intersecting a line-path associated with the projection line and emitted while the radiation source was at a particular segment of a radiation source trajectory.
