Abstract
Digital Subtraction Angiography (DSA) is a method used in angiography systems for endovascular diagnosis and treatment. An image of the blood-vessels is created by subtracting the mask image acquired before injecting contrast agent from the live image acquired after the contrast agent has been injected. DSA does not include images other than blood-vessels and exhibits excellent low contrast resolution. We have developed "Flex-APS," interventional radiology support software that produces fewer artifacts and provides higher DSA image quality. This function has the following specifications
(1) Enables automatic nonlinear artifact correction to three dimensional movements in DSA images
(2) Enables automatic artifact correction in real time in DSA images
