Bolus-chasing CT Angiography - Catch the Contrast via Control
MetadataShow full item record
Intravenous injection of contrast media is required to enhance conspicuity of the vasculature, organs and tumors in CT angiography (CTA) for diagnosis of cardiovascular structures, peripheral vessels and solid organs. The overall goal of this project is to develop boluschasing CTA for a wide class of diagnostic applications. This will be achieved by instantaneously reconstructing CT images, dynamically predicting bolus propagation, and adaptively varying scanning pitch from the aortic arch to the feet to allow real-time correction of any significant deviation from the prediction. *Complimentary film demonstrates the solution to resonating the bolus peak and imaging aperture of the CTA angiography function, that is, via real-time peak bolus identification and prediction as well as adaptively moving the patient table.
