  • X-ray imaging condition modification method and x-ray system
    Patent number: 10610188
    Abstract: An x-ray imaging condition modification method includes modifying a first imaging condition to a second imaging condition by changing a value of at least one parameter among parameters included in the first imaging condition to an arbitrary value, and changing values of remaining parameters that are parameters other than the at least one parameter using the arbitrary value and an approximate function.
    Type: Grant

  • Method for generating approximate function of total MTF of X-ray image, based on conditions for imaging with X-ray
    Patent number: 10172584
    Abstract: A method for generating approximate functions of total MTFs of x-ray images, based on conditions for imaging with an x-ray emitted by an x-ray tube, includes: a first generating step of generating an approximate function of an MTF based on an x-ray tube effective focal spot value on an object plane; a second generating step of generating an approximate function of an MTF based on the kind of an x-ray detector system on the object plane; a third generating step of generating an approximate function of an MTF based on the amount of motion of an object; and a fourth generating step of generating an approximate function of a total MTF.
