A method () of aneurysm analysis () and virtual stent simulation () for endovascular treatment of sidewall intracranial aneurysms.

Method for intracranial aneurysm analysis and endovascular intervention planning

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.

Method of visualization of contrast intensity change over time in a DSA image

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.

Automated image data subtraction system suitable for use in angiography

A system for visualizing vascular fluid flow concentration includes at least one repository including a plurality of stored angiography scenes, an angiography scene comprises a plurality of individual images of a vascular structure successively acquired over a time period. A user interface control device enables a user to determine, (a) a duration and (b) a start time relative to a start time of the time period, of a window of interest within the time period. A control processor is electrically coupled to the user interface control device and the at least one repository. Control processor automatically assigns a unique visual indicator representing contrast flow of fluid through vessels to individual images within the user determined duration of the time period. A display processor, electrically coupled to the control processor and the user interface control device and at least one repository, generates data representing at least one display image comprising a composite image including individual images within the user determined duration of the time period having a unique assigned visual indicator.

System for visualizing regions of interest in medical images

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.
