Global InformationDigital variance angiography information
Digital variance angiography (DVA) is a novel image processing method based on kinetic imaging, which allows the visualization of motion on image sequences generated by penetrating radiations. DVA is a specific form of kinetic imaging: it requires angiographic image series, which are created by X-ray or fluoroscopic imaging and by the administration of contrast media during various medical procedures. The resulting single DVA image visualizes the path of contrast agent with relatively low background noise.[1]
Between 2017 and 2019, two clinical studies have been performed to investigate the clinical usability of DVA and these studies have found that it has the potential to be used for low-dose radiographic imaging and carbon-dioxide angiography in the future.[1][2]
DVA is currently under development by Kinetic Health Ltd. and Semmelweis University (Budapest, Hungary).
