摘要： A system provides recovery from an X-ray system C-arm and patient table collision. A collision recovery system enables a user to recover from a collision or near collision of movable components of an X-ray imaging system including a movable C-arm hosting an X-ray emitter and detector. The system includes a C-arm position tracking processor for automatically recording C-arm position data indicating a valid stationary position of a C-arm and a path from the valid stationary position to an invalid position of the C-arm enabling retracement of the C-arm along the path to the valid stationary position. A user interface enables a user to initiate retracement of the C-arm along the path to the valid stationary position. A C-arm is movable to retrace the path to the valid stationary position using the recorded C-arm data in response to user command.

摘要： An X-ray imaging system automatically calculates blood flow travel time by using an X-ray image acquisition system to initiate acquisition of images at a second anatomical site synchronized with introduction of contrast agent into a patient vessel at a first anatomical site. A detector automatically compares images, acquired at the second anatomical site in response to the introduction of contrast agent, with images of the second anatomical site acquired in the absence of a contrast agent, to detect when contrast agent reaches the second anatomical site via blood flow in a circulatory system of the patient. A calculator automatically calculates a blood flow travel time duration between the first and second anatomical sites based on the time elapsed between time of the introduction of contrast agent and a time the contrast agent reaches the second anatomical site in response to the detection. An output processor automatically generates a message indicating the calculated blood flow travel time.

摘要： An image data subtraction system receives an electrical signal representing a heart cycle electrical waveform during multiple heart cycles and acquires data representing a first image set comprising multiple temporally sequential individual mask images of vessels of a portion of patient anatomy during the multiple heart cycles in the absence of a contrast agent. The system acquires data representing a second image set comprising a multiple temporally sequential individual contrast enhanced images of vessels of the portion of patient anatomy during the multiple heart cycles in the presence of a contrast agent. An image data processor automatically uses the electrical signal to identify temporally corresponding pairs of images comprising a mask image and a contrast enhanced image acquired substantially at a same point within a heart cycle. The image data processor, for the corresponding pairs, automatically subtracts data representing a mask image of a corresponding pair from a contrast enhanced image of the corresponding pair, to provide subtracted images.

A collimator includes at least one portion of X-ray absorbent material automatically adjustable to alter the dimensions of a spatial cross section of an X-ray beam of radiation, in response to a control signal. A collimator controller generates the control signal in response to, determining one or more regions of the X-ray detector corresponding to a portion of patient anatomy to be X-rayed in response to X-ray absorbent markers indicating boundaries of the portion of patient anatomy during an initialization X-ray exposure for individual steps of the series of pre-programed steps and determining different positions of the portion of X-ray absorbent material for corresponding individual steps of a series of pre-programed steps in response to the determined regions. An X-ray imaging device automatically moves an X-ray detector and X-ray emitter combination relative to patient anatomy in a series of pre-programed steps, in response to data representing the determined series of pre-programed steps and user command. The X-ray imaging device automatically adjusts the position of the portion of X-ray absorbent material via the control signal.

摘要： An X-ray imaging system performs automated multi-step imaging of patient anatomy and includes an X-ray imaging device. The X-ray imaging device supports automated movement of an X-ray detector and X-ray emitter combination relative to patient anatomy in a series of pre-programmed steps. A multi-step programming interface enables a user to select, (a) a start position for X-ray imaging at a first location of a portion of patient anatomy and (b) an end position for X-ray imaging at a second location of a portion of patient anatomy. A computation processor automatically determines a series of pre-programmed steps comprising multiple incremental distances to be moved by the X-ray detector and X-ray emitter combination relative to the portion of patient anatomy in response to predetermined data including, (i) the selected start and end positions, (ii) the length of the portion of patient anatomy imaged in an individual step and (iii) the amount of overlap desired between successive X-ray images. An imaging controller initiates automated multi-step imaging of the portion of patient anatomy by the X-ray imaging device in response to data representing the determined series of pre-programmed steps and user command.
