Abstract:
1. A method for gastric artery chemical embolization (GACE), comprising: before beginning a GACE catheterization procedure on a subject, operating an x-ray imaging system to acquire a first, current image data set of the fundus of the subject; also before beginning implementation of said GACE catheterization procedure, operating said x-ray imaging system to acquire a second current image data set that shows blood vessels that supply the fundus, and highlighting the gastric artery of the subject in said second current data set; providing said first current data set and said second current data set to a processor and, in said processor, fusing said first and second current image data sets to form a first fusion image data set; beginning said GACE catheterization procedure on said subject and, during said GACE catheterization procedure, acquiring a catheter position-indicating data set that includes a position of a catheter, used in said GACE catheterization procedure, in the subject; in said processor, fusing said first fusion image data set with said catheter position-indicating data set, to obtain a second fusion image in which the fundus and blood vessels that supply the fundus are visible and that shows a current position of the catheter in the subject relative to the fundus and the blood vessels that supply the fundus; and displaying said second fusion image during said GACE catheterization procedure at a location relative to the subject that allows a physician implementing the GACE catheterization procedure to view the second fusion image.
