US 2018/0279984 A1 · Determination and Presentation of Flow Transit Curves

Abstract

A system and method includes reception of an indication of a region of interest of a plurality of image frames, determination of a first set of pixel locations of the region of interest which depict blood vessels, determination of a second set of pixel locations of the region of interest which depict non-vessel tissue, determination, for each of the plurality of the image frames, of a first contrast medium concentration corresponding to the first set of pixel locations, determination, for each of the plurality of the image frames, of a second contrast medium concentration corresponding to the second set of pixel locations, and display of a visualization depicting a first contrast medium concentration and a second medium concentration with respect to the respective time of each of the plurality of the image frames.

A system comprising:

an X-ray detector and an X-ray source operable to:
acquire a plurality of image frames of a patient volume, each of the plurality of image frames depicting a contrast medium within the patient volume at a respective time;
a processor to:
receive an indication of a region of interest of the image frames;
determine a first set of pixel locations of the region of interest which depict blood vessels;
determine a second set of pixel locations of the region of interest which depict non-vessel tissue;
for each of the plurality of the image frames, determine a first contrast medium concentration corresponding to the first set of pixel locations;
for each of the plurality of the image frames, determine a second contrast medium concentration corresponding to the second set of pixel locations;
and
a display to display a visualization depicting a first contrast medium concentration and a second medium concentration with respect to the respective time of each of the plurality of the image frames.
