Matched Filtering for Digital Subtraction Angiography
Digital fluoroscopy methods are providing powerful diagnostic tools for imaging dilute amounts of contrast materials flowing through the cardiovascular anatomy. The predominate processing algorithms which have proven successful are temporal (1–6) and energy (7–9) subtraction schemes. The most common application of these subtraction methods has been in conjunction with intravenous angiography; although, intra-arterial studies also benefit from such processig (10). All these methods may be lumped together under the heading “digital subtraction angiography”.
