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.

摘要： A system displays potential radiation zones in an angiography X-ray laboratory during an angiography procedure, for example, and identifies areas of potentially harmful radiation due to X-ray scatter in an imaging room. An input processor receives data identifying an emitted X-ray dose level applied to an area of a patient anatomy. An image data processor determines level of X-ray radiation dose scatter in different regions of an imaging room indicating regions of potentially harmful radiation, by calculating X-ray scatter dose at different distances from an irradiated patient area as being substantially in proportion to the size of the irradiated area and substantially inversely proportional to the square of the distance from the irradiated area. A visual alert system visually identifies areas of a room of potentially harmful radiation in response to the determination.

摘要： A system identifies a stent in an image using luminance density and anatomical information. An X-ray imaging system automatically detects and indicates location of an invasive anatomical device in an image. An interface acquires, data representing X-ray images of patient vessels and data identifying a particular vessel containing a medical device. An image data processor employs a model of anatomical vessels to select a region of interest in a vessel identified by the acquired data and automatically determines a location of the medical device in an acquired image by determining at least a portion of an outline of the medical device by detecting a luminance transition in the acquired image using an image edge detector. A display processor initiates generation of data depicting location of the medical device in the acquired image in response to determining the at least a portion of the outline of the medical device.

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 X-ray imaging system performs automated imaging of patient anatomy. 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.
