Abstract: Disclosed herein is a framework for facilitating adaptive control of monitoring devices. In accordance with one aspect, a position detector detects a chest elevation level and provides chest elevation level data. A processor uses the chest elevation level data to determine a heart elevation level with respect to a reference level. A comparator compares the determined heart elevation level with an elevation level of a monitoring device with respect to the reference level. In response to the comparison, a movement system adjusts the elevation level of the monitoring device.

Abstract: Disclosed herein is a framework for facilitating reporting. In accordance with one aspect, the framework generates a first outline of a first region of interest in pre-procedural image data. The pre-procedural image data may be acquired from a subject before a medical procedure is performed on the subject. The framework may further generate a second outline of a second region of interest in post-procedural image data. The second outline corresponds to the first outline and may be acquired from the subject during or after the medical procedure is performed on the subject. A pictorial report of the medical procedure may then be generated based at least in part on the first and second outlines.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system positions a patient for X-ray imaging of a Left Atrium of a heart, using an imaging system for, acquiring data representing a frontal first X-ray image and representing a lateral second X-ray image of a patient. A display processor initiates generation of data representing a first composite display image including the first X-ray image and a first graphical overlay for aligning with vertebra in the first X-ray image. The display processor initiates generation of data representing a second composite display image including the second X-ray image and a second graphical overlay for aligning with vertebra in the second X-ray image. The imaging system is positioned for imaging a heart left atrium in response to movement of a table supporting the patient to align the first graphical overlay with the vertebra in the first X-ray image and to align the second graphical overlay with the vertebra in the second X-ray image.

Abstract: 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.
