摘要： A system comprises a catheter including a lens, for acquiring optical coherence tomography images within the vessel of interest as the catheter is being retracted from the vessel in the presence of contrast agent. An X-ray imaging system interface receives a first set of X-ray images of an anatomical region including the vessel of interest containing the catheter. The first set of X-ray images are acquired at points corresponding to the particular points within a heart cycle, while the catheter is stationary in the vessel, in response to a heart electrical activity representative signal and in the absence of contrast agent. An image data processor associates the received X-ray images and corresponding optical coherence tomography image data derived at corresponding time points within respective acquisition heart cycles.

摘要： A method generates a two dimensional (2D) medical image through a three dimensional (3D) imaged volume of patient anatomy at a desired position, by storing 3D image data representing a 3D imaging volume including vessels in the presence of a contrast agent. The 3D image data comprises, data identifying multiple voxels representing multiple individual volume image element luminance values and luminance distribution data for individual voxels of a vessel in the 3D image data. For multiple individual voxels of a 2D image, the method determines composite luminance distribution data of an individual voxel in the 2D image by combining luminance distribution data of the 3D image data of multiple identified voxels substantially lying on a projection line from a source point to the individual voxel and generating data representing the 2D image using the determined composite luminance distribution data of the multiple individual voxels.

摘要： A system creates a visually (e.g., color) coded 3D image that depicts 3D vascular function information including transit time of blood flow through the anatomy. A system combines 3D medical image data with vessel blood flow information. The system uses at least one repository for storing, 3D image data representing a 3D imaging volume including vessels, in the presence of a contrast agent and 2D image data representing a 2D X-ray image through the imaging volume in the presence of a contrast agent. An image data processor uses the 3D image data and the 2D image data in deriving blood flow related information for the vessels. A display processor provides data representing a composite single displayed image including a vessel structure provided by the 3D image data and the derived blood flow related information.

摘要： A system automatically processes different medical image sequences facilitating comparison of the sequences in adjacent respective display areas. An image data processor, identifies first and second mask images of first and second image sequences respectively as images preceding introduction of contrast agent and determines a translational shift between the first and second mask images. The image data processor transforms data representing individual images of at least one of the first image sequence and the second image sequence in response to the determined translational shift to reduce mis-alignment of the individual images of the first image sequence relative to the individual images of the second image sequence. A display presents first and second image sequences corrected for mis-alignment, in substantially adjacent display areas to facilitate user comparison.

摘要： A method and system provides medical image processing and 3-dimensional image construction of an examination subject. A user is enabled to selectively orient an x-ray imaging system having a variable 3-dimensional acquisition axis relative to an examination subject support for holding an examination subject. A non-planar image data acquisition path is set for the x-ray imaging system oriented around the variable 3-dimensional acquisition axis in response to user instruction. Acquisition of image data of the examination subject is initiated by the x-ray imaging system at a plurality of points along the non-planar image data acquisition path. A 3-dimensional image is constructed from the acquired image data such that any metal artifacts introduced by radio-opaque objects within the examination subject are minimized. The 3-dimensional image is displayed.

摘要： An image data processing system automatically indicates an image of a digitally subtracted Angiography (DSA) image sequence is associated with at least one of, arterial, venous, or capillary phases of blood flow. The system includes an interface for acquiring data representing a DSA sequence of digitally subtracted images enhancing vessel structure. An image data processor automatically indicates an image of the DSA sequence is associated with at least one of, arterial, venous, or capillary phases of blood flow by determining individual minimum luminance intensity level values of individual images of the DSA sequence and using the determined individual minimum luminance intensity level values in identifying images of the DSA sequence are associated with at least one of, arterial, venous, or capillary phases of blood flow. An output processor automatically assigns an attribute to image data to identify vessel phase in response to the identifying images of the DSA sequence.
