Guidance of intracoronary radiation therapy based on dose-volume histograms derived from quantitative intravascular ultrasound
The authors present a new modality of dosimetry based on a method that three-dimensional (3-D) image reconstruction of electrocardiogram (ECG)-gated intravascular ultrasound (IVUS) images for optimal dose prescription in vascular interventional radiation therapy. Expand

Blood velocity estimation with high frequency intravascular ultrasound
When a cluster of randomly distributed blood particles moves across the ultrasound beam, the received echo signals decorrelate as a function of time. This phenomenon may be used to estimate the flowExpand
