Abstract: The present invention relates to production of 2D digital images suitable for use in medical imaging. The invention particularly relates to remapping X-ray images taken from a first viewpoint so that they present the same image as seen from a second viewpoint. Remapping is achieved by registering separate 2D images taken from the first and second viewpoints of an area with a 3D scan volume of the same region to ascertain their relative viewpoints with respect to the 3D scan volume. The image taken with respect to the first viewpoint is then remapped to yield the image as seen from the second viewpoint.

Abstract: The invention relates to evaluation of maturity of arteriovenous (AV) fistula using guidewires that measure intravascular blood flow and/or pressure. The invention provides methods of evaluating AV fistula maturation using an instrumented guidewire to measure intravascular flow and/or pressure. By using a small diameter guidewire that does not interfere substantially with the flow, an accurate measurement can be made that is useful for identifying when a fistula is mature and therefore ready to be used for hemodialysis. The flow of blood through the fistula is measured using the guidewire and the measured flow and/or pressure of blood is used to determine if the fistula is mature.
