Abstract:
1. A data management system for use in Angiographic X-ray imaging, comprising: a first memory portion for storing first image frame data representing minimum luminance values of individual pixels of a sequence of medical images acquired during introduction of a contrast agent into patient vasculature, an individual pixel minimum luminance value is substantially the lowest pixel value of the plurality of pixel values for a particular pixel position occurring in said sequence of medical images; a second memory portion for storing second image frame data comprising a difference between said minimum luminance values and corresponding maximum luminance values, said maximum luminance values comprising maximum luminance values of individual pixels of said sequence of medical images, an individual pixel maximum luminance value is substantially the highest pixel value of the plurality of pixel values for a particular pixel position occurring in said sequence of medical images; and an image data processor for processing data representing an acquired X-ray image frame of a catheterized vessel using said second image frame data to provide an image with enhanced visualization of a catheter in a vessel.
