    摘要: A system for selecting an anatomical image for display includes a main image display displaying at least one anatomical image; a touch-screen display; a processing unit providing a selection of graphical directories of anatomical images; and a network configured to interface the main image display with the processing unit and configured to interface the touch-screen display with the processing unit. The system displays at least one of the selection of graphical directories of anatomical images on the touch-screen display and enables selecting at least one of the selection of graphical directories from the processor without removing the anatomical image from the main image display. The touch-screen display includes a button enabling interchangeable display of the anatomical image and the selection of graphical directories of anatomical images. The system enables selecting at least one anatomical image by touching the corresponding image in the directory displayed on the touch-screen display.

    摘要: An IVUS catheter is advantageously provided with a particular radio-opaque pattern enabling detection of catheter rotation angle with respect to an X-ray imaging source for co-registering IVUS image data with angiographic X-ray or CT image data, for example. An ultrasound catheter system supports orientation and display of intra-vascular ultrasound imaging data. The system comprises an ultrasound catheter for acquiring ultrasound images comprising a body having a pattern of radio-opaque material on the external surface of the catheter body. The pattern varies with angular rotation of the catheter and indicates an angle of rotation of a predetermined reference orientation of the catheter relative to an X-ray radiation source, so that an X-ray image of the catheter body indicates the pattern and the pattern is analyzable by an image data processor to determine the angle of rotation.

    摘要: An Angiographic X-ray imaging system provides enhanced image feature visualization. At least one repository includes data representing a sequence of X-ray images of a portion of patient anatomy acquired over a time interval and signal data representing electrical activity of the heart of the patient over the time interval. An image data processor determines for individual images of the sequence of X-ray images, characteristics of a portion of the signal data associated with a corresponding image. The characteristics comprise at least one of, (a) a peak to peak value of a portion of the signal data associated with a corresponding image and (b) an average value of a portion of the signal data associated with the corresponding image. The image data processor selects a set of images exclusive of particular images from the sequence of X-ray images in response to the determined characteristics and generates an averaged image from the set of images.

    摘要: A system provides a roadmap image displaying a vessel structure using an imaging system to acquire data representing multiple temporally sequential individual images of vessels of a region of interest of patient anatomy in the presence of a contrast agent. An image data processor generates multiple sequential cumulative images corresponding to the individual images and an individual current cumulative image corresponds to a current image of the individual images. The current cumulative image comprises cumulative pixel luminance values and an individual cumulative pixel luminance value is generated from luminance values of pixels, spatially corresponding to the individual cumulative pixel and present in images comprising a subset of the individual images. The subset comprises contiguous images of the temporally sequential individual images acquired preceding the current image and including the current image. An output processor provides the multiple sequential cumulative images to a destination.

    摘要: A system reduces artifacts introduced by patient or table motion during generation of a composite image visualizing contrast agent flow. A system for generation of a composite medical image of vessel structure, includes an imaging device for acquiring multiple sequential images of vessel structure of a portion of patient anatomy in the presence of a contrast agent. An imaging processor aligns individual images of the multiple sequential images with a single particular mask image containing background detail of the portion of patient anatomy in the absence of contrast agent. The imaging processor forms data representing multiple digitally subtracted images by subtracting data representing the single particular mask image from aligned individual images of the multiple sequential images. The imaging processor associates different individual images of the multiple digitally subtracted images with different corresponding visual attributes and combines data representing the digitally subtracted images to form a composite image. A reproduction device presents the composite image to a user.

    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.
