Abstract
Official abstract text for this publication.
A method is disclosed for processing measurement data from perfusion computed tomography, in which both perfusion parameters, in order to calculate which arterial and venous TACs are generated, and dynamic CTA images are generated from the measurement data. In at least one embodiment of the proposed method, averaging is performed over the dynamic CTA images from a plurality of temporally successive time phases in order to obtain averaged CTA images, wherein the time phases over which averaging is performed are determined from the arterial or venous TAC(s). In some cases, the method can dispense with an additional static CTA and so the amount of the injected contrast agent and the radiation dose can be reduced.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for processing measurement data from perfusion computed tomography (CT), comprising: calculating perfusion parameters and at least one dynamic CT-angiography image from the measurement data, the measurement data being gathered by an Adaptive 4D CT scanner such that a same one of the measurement data gathered at a same time is used to calculate both the perfusion parameters and the dynamic CT-angiography image, the dynamic CT-angiography image associ…
