摘要： System for live 3D x-ray viewing comprising an x-ray source, an x-ray detector, a processing unit, a monitor and means for detecting viewer's eyes, wherein the x-ray source and the x-ray detector are arranged at a movable C-arm. The x-ray source comprises two focal spots, wherein a separation of the two focal spots is adjustable so that the image acquisition angle between the two focal spots matches the viewing angle between the two eyes.

摘要： Method for estimating radiation dose received by a tissue of interest during an imaging scan comprising: i. obtaining image data of a body region including the tissue of interest, ii. sub-dividing the image data into axial slices, comprising tissue axial slices and non-tissue axial slices, iii. determining a net amount of radiation dose emitted or received by each axial slice by combining scan parameters of each axial slice with pre-calculated amounts of radiation dose, iiii summing the net amounts of radiation dose of all the tissue axial slices to obtain a tissue dose.

摘要： A method for extending initial image data of a subject for dose estimation includes obtaining first image data of the subject for dose calculation, wherein the first image data has a first field of view. The method further includes obtaining second image data for extending the field of view of the first image data. The second image data has a second field of view that is larger than the first field of view. The method further includes extending the first field of view based on the second image data, producing extended image data.

摘要： The invention relates to an apparatus (18) for calculating an x-ray dose distribution within an object for a computed tomography examination. A primary flux determination unit (15) determines firstly a primary flux distribution within the object, wherein then this determined primary flux distribution is used as an initial total flux distribution by a total flux determination unit (16) while applying a six- flux model algorithm. This allows the determination of the total flux distribution to start with a relatively good first approximation of the total flux distribution such that the six- flux model algorithm can determine the total flux distribution very fast. The determined total flux distribution is finally used by a dose distribution determination unit (17) for determining a total dose distribution. The apparatus allows therefore for a very fast determination of x-ray dose distributions for computed tomography examinations.
