  • Patent number: 11399791
    Abstract: A system and method is provided for imaging a contrast agent. The system includes a power injector that delivers a contrast agent as a series of boluses using a known period, flow rate, or duration and with a rate of at least one or more separate boluses per cardiac cycle. An x-ray imaging system acquires a reference dataset of the subject before the contrast agent is delivered and acquires an imaging dataset as the series of boluses are delivered to the subject, wherein multiple images are acquired of the subject per bolus. A computer system receives the reference dataset and the imaging dataset from the x-ray imaging system and reconstructs the reference dataset and the imaging dataset using a reconstruction process that removes the subject from the images to generate time-resolved volumetric images of the contrast agent moving within a volume of the subject without the subject.

  • Patent number: 10492739
    Abstract: An X-ray CT device according to an embodiment includes a gantry, a top board, and a movement mechanism. The gantry includes an X-ray tube that generates X-rays and a detector that detects the X-rays. The top board inserts the subject into the opening section of the gantry. The movement mechanism moves the top board in a longitudinal direction. Furthermore, the position of the top board in a vertical direction at the position that intersects with the path of the X-rays is changed at substantially the same slope relative to the movement distance of the top board when the top board is moved in the longitudinal direction.

  • Patent number: 10470701
    Abstract: Monitoring system configured to provide a health chart on an operator display. The health chart includes a plurality of indicators that identify patient parameters. The plurality of indicators form a column that extends parallel to a first axis. The health chart also includes linear projections that are aligned with respective indicators and extend parallel to a second axis that is perpendicular to the first axis. The linear projections represent values of the patient parameters that correspond to the respective indicators. The values are determined by the physiological data obtained from corresponding sensors. The patient monitoring system is configured to determine lengths of the linear projections based on the physiological data. The lengths extend from proximal ends of the linear projections to distal ends of the linear projections. The distal ends move parallel to the second axis toward or away from the respective indicators to change the length.

  • Patent number: 10271812
    Abstract: A dynamic CT imaging method is provided. With the method, projection measurement data for a region of an examination object to be imaged is captured, with simultaneous correlated capture of the respiratory movement of the examination object. A phase of the respiratory movement, for which image data is to be reconstructed, is selected. Phase projection measurement data assigned to the selected phase is also determined. Transition regions of partial images of the region to be imaged between successive respiratory cycles are then reconstructed on a trial basis based on a part of the phase projection measurement data, and a standard reconstruction is performed using parts of the phase projection measurement data for each of the successive respiratory cycles assigned to an optimum reconstruction.
