20090022269 | RADIATION IMAGING APPARATUS - A radiation imaging apparatus that performs radiation imaging of a breast of a subject, which includes a table for laying down the subject; a receiving section that receives a breast of the subject laid on the table in a supine position; a radiation imaging section including a radiation emission unit and a radiation detection unit each located at a position opposing to each other being interposed by the breast of the subject received in the receiving section; and a drive unit that shifts the receiving section to a position suitable for imaging the breast of the subject. | 01-22-2009 |
20090252287 | Operating method for a swiveling polyplanar imaging system for time-resolved imaging of an object being examined - An operating method for a polyplanar imaging system for time-resolved imaging of an object is provided. First and second data records are recorded at a fan angle β from different angular positions by a first and second imaging planes arranged at an offset angle γ relative to each other and swiveled through an angle of at least φ=180°+β. A third data record is created by selecting projection images from the first data record beginning from a starting angle α and from the second data record so that the third data record covers an angular range of at least φ. Three-dimensional images are reconstructed based on the third data record. The starting angle α is varied for continuously creating the third data record until α has attained its final value. The contrast of projection images in the third data record or of three-dimensional images is evaluated. | 10-08-2009 |
20100067651 | METHODS AND APPARATUS FOR X-RAY IMAGING WITH FOCAL SPOT DEFLECTION - Methods and apparatus for x-ray imaging with focal spot deflection are provided.

20140328454 | SYSTEM AND METHOD FOR DETERMINING AN ORIENTATION OF RESERVOIR GEOBODIES FROM UNORIENTED CONVENTIONAL CORES - A system and method for determining an orientation of a reservoir feature from an unoriented core. The method includes selecting an arbitrary inclined plane in a longitudinal or transverse cross sectional CT scan image of the unoriented core; flattening the inclined plane by realigning all voxels within a volume of the unoriented core so as to obtain a horizontal plane in a realigned core; selecting a transverse cross sectional CT scan image of the realigned core where a desired feature is present; determining a correcting angle to be added to an angle of a flat-bed contact plane of the realigned core relative to a reference mark in the realigned core to obtain a correct inclination angle relative to compass map coordinates; determining a first angle between a direction perpendicular to the feature relative to the reference mark; and determining a second angle by adding the correcting angle to the first angle. | 11-06-2014 |
