    摘要: A system provides a display image enabling a user to visualize and compare blood flow characteristics over time at selected points in an angiographic X-ray image. A system and user interface enables user interaction with a medical vessel structure image to determine individual vessel blood flow characteristics. The system includes a user interface cursor control device and a display processor for generating data representing a single composite display image. The composite display image includes, a first image area showing a patient vessel structure and contrast agent flow through the patient vessel structure over a first period of time and a second image area showing a graph of contrast agent concentration in a particular portion of the vessel structure over a second period of time. The particular portion of the vessel structure is selected in response to user command using the cursor control device.

    摘要: An image data subtraction system suitable for use in Angiography or other medical procedure enhances vessel visualization. An imaging system subtracts data representing a first mask image from data representing temporally sequential individual images of patient vessels to provide first digitally subtracted images. The sequential individual images encompass introduction of a contrast agent. An image processor automatically, processes the data representing the first digitally subtracted images to identify a first image indicating presence of the contrast agent and a second image preceding the first image by determining a measure representing a net presence of contrast agent in an individual digitally subtracted image. The second image is substantially exclusive of an indication of presence of the contrast agent. The image processor automatically, selects the second image as a second mask image and subtracts data representing the second mask image from the data representing images of the temporally sequential individual images to provide second digitally subtracted images. A user interface presents the second digitally subtracted images for display while the patient is undergoing a medical procedure.

    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 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 motion compensated digitally subtracted Angiography (DSA) image processing system includes an interface for acquiring a sequence of images of patient vessels both prior to and following introduction of contrast agent into the vessels. An image data processor automatically, (a) determines a first shift vector for a first image of the sequence for compensating for shift between the first image and a first reference image of the sequence, (b) applies the determined first shift vector to the first image of the sequence to produce a shifted image, (c) subtracts the first reference image from the shifted image to produce a subtracted image enhancing vessel structure, (d) determines a second shift vector for compensating for shift between the subtracted image and a second reference image and (e) shifts content of the subtracted image relative to the second reference image in response to the second shift vector, to provide a shifted subtracted image enhancing and aligning vessel structure.
