  • Method for generating a combined projection image and imaging device
    Patent number: 9836858
    Abstract: A method for generating a combined projection image from a medical inspection object, includes steps of capturing a set of initial projection images; reconstructing a first and a second three-dimensional volume from the set of initial projection images; generating a first re-projection image from the first three-dimensional volume and a second re-projection image from the second three-dimensional volume; weighting the first re-projection image and the second re-projection image; and combining the weighted first re-projection image and second re-projection image for generating the combined projection image.
    Type: Grant
    Filed: September 19, 2014
    Date of Patent: December 5, 2017
    Assignee: Siemens Aktiengesellschaft
    Inventors: Shiras Abdurahman, Anna Jerebko, Michael Kelm
  • Method and apparatus for projection image generation from tomographic images
    Patent number: 9569864
    Abstract: A method for generating a projection image from tomographic images first captures (S101) a number of stacked two-dimensional tomographic images representing a tomographic volume. The pixels of the stacked two-dimensional tomographic images are weighted (S102) along a number of projection beams through the tomographic volume with weighting factors that are chosen under the constraint that the sum of all squared weighting factors for each individual projection beam is between a given lower limit and a given upper limit. Then the weighted pixels are summed up (S103) along the number of projection beams for generating the two-dimensional projection image.
