System for Processing Medical Image data to Provide Vascular Function Information
First Claim
1. A system for combining 3D medical image data with vessel blood flow information, comprising:
- at least one repository for storing,3D image data representing a 3D imaging volume including vessels in the presence of a contrast agent and2D image data representing a 2D X-ray image through said imaging volume in the presence of a contrast agent;
an image data processor for using said 3D image data and said 2D image data in deriving blood flow related information for said vessels; and
a display processor for providing data representing a composite single displayed image including a vessel structure provided by the 3D image data and the derived blood flow related information.

Abstract
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.

10. A system for combining 3D medical image data with vessel blood flow information, comprising:
-
an image data processor for, using 3D image data representing a 3D imaging volume including vessels in determining a first transit time curve for an individual volume image element comprising said vessels, an individual transit time curve identifying imaging luminance content representative values of an individual image element over a time period, using 2D image data representing at least an X-ray image through said imaging volume in determining a second transit time curve for said individual volume image element comprising said vessels in said imaging volume and processing said second transit time curve to compensate for difference between said first and second transit time curves to provide a compensated transit time curve; and a display processor for providing data representing a single composite displayed image comprising a vessel structure including blood flow related information derived using said compensated transit time curve and said 3D image data. - View Dependent Claims (11)

12. A system for combining 3D medical image data with vessel blood flow information, comprising:
-
an image data processor for, using 3D image data representing a 3D imaging volume including vessels in determining a first transit time curve for an individual volume image element comprising said vessels, an individual transit time curve identifying imaging luminance content representative values of an individual image element over a time period, using 2D image data representing an X-ray image through said imaging volume in determining a second transit time curve for said individual volume image element comprising said vessels in said imaging volume and compensating for difference between said first and second transit time curves by, comparing first and second transit time curves of said individual volume image element, deriving a scaling function for said individual volume image element in response to the comparison and scaling said second transit time curve using said scaling function to provide a compensated transit time curve; and a display processor for providing data representing a composite single displayed image including a vessel structure provided by the 3D image data and blood flow related information derived using said compensated transit time curve. - View Dependent Claims (13, 14, 15)
