    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. The system comprises an imaging system for acquiring, during a medical procedure, data representing multiple temporally sequential individual images of vessels of a portion of patient anatomy. The sequential individual images encompass introduction of a contrast agent. An image processor automatically processes the data representing the multiple temporally sequential individual images to identify a first image indicating presence of the contrast agent and a second image preceding the first image by comparing a difference between measures representative of luminance content of the first and second image, with a threshold. The second image is substantially exclusive of an indication of presence of the contrast agent. The image processor, in response to the difference exceeding the threshold, automatically selects the second image as a mask image and subtracts data representing the mask image from data representing images of the temporally sequential individual images to remove background image detail and emphasize vessel structure in providing processed image data for display. A user interface presents the processed image data for display while the patient is undergoing the medical procedure.

    摘要: An automated medical image storage system comprises an interface, a configuration interface and an output processor. The interface acquires a sequence of images of patient vessels both prior to and following introduction of contrast agent into the vessels and subtracts a mask image representing background detail in the absence of a contrast agent to produce data representing a DSA sequence of digitally subtracted images enhancing vessel structure. The configuration interface enables a user to configure image processing (e.g., pixel shift, edge enhancement) and selection of images from the sequence of images for automatic documented archiving in an archival system by determining criteria to select images associated with one of arterial, venous, or capillary phases of blood flow. The output processor automatically initiates storage of images selected from the sequence of images in response to the determined criteria.

    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.
