  • Patent number: 10285664
    Abstract: Disclosed herein are an X-ray imaging apparatus for photographing a marker provided in an X-ray detector with a camera to acquire information about the distance between the X-ray detector and an X-ray source or information about the pose of the X-ray detector at low cost The X-ray imaging apparatus may include an X-ray source that generates X-rays and irradiates the X-rays. A photographing device installed in the X-ray source photographs a marker image. A controller outputs, when a marker of a plurality of markers constituting a multi-marker array formed in a surface of an X-ray detector is not detected from the marker image, a notice informing that no marker is detected. The controller detects a single marker from another marker image photographed after the notice informing that the marker is not detected is outputted.

  • Patent number: 10272266
    Abstract: The present invention relates to correlating a position of a radiation beam with a position of a target to be irradiated which is contained in a structure having a repetitive motion comprising a plurality of successive motion cycles. External position data is acquired, which describes a position the structure during different motion cycles and/or time periods. Target data is acquired, which describe a position of the target during the motion cycles and/or time periods. A correlation model is generated, which correlates the external position and the target position. A predicted target position during a motion cycle is determined based on the correlation model and acquire external position data. Primary verification data is determined that describes an difference between actual and predicted target position. When the prediction is accurate, a further prediction and verification of the target position in later motion cycles can be performed.

  • Patent number: 10251617
    Abstract: An X-ray fluoroscopic imaging apparatus controls movement of shield plates so that a length of a first pre-image in an x direction is larger than a length of a strip image. A capturing position of the first pre-image is adjusted so that an upper end of the first pre-image matches an upper end of a capturing range of a long image. Thus, where a long region is set on the basis of the first pre-image at present, it is possible to check whether a desired X-ray image is included in a strip image. It is possible to correct a position of an imaging system to an appropriate position as an imaging start point by referring to an X-ray image included in the first pre-image having a large amount of information. Therefore, it is possible to acquire a long image appropriate for diagnosis through slot imaging using this apparatus.

  • Patent number: 10238358
    Abstract: Systems and methods of estimating radiation dose include obtaining at least one radiation exposure value from a location marked on a patient model. A radiation exposure of the patient is estimated using a dose model which includes the patient model. At least one correction factor is calculated based upon the radiation exposure value and the estimation of radiation exposure using the dose model. The at least one correction factor is applied to the dose model and a refined estimation of radiation exposure is produced based upon the at least one correction factor and the dose model.
