Titel:
Vascular 3D+T Freehand Ultrasound using Correlation of Doppler and Pulse-Oximetry Data
Abstract:
W presentent a new system to acquire and reconstruct 3D freehand ultrasound volumes from arbitrary 2D image acquisitions over time. Motion artifacts are significantly reduced with a novel gating approach which correlates pulse oximetry data with Doppler ultrasound. The reconstruction problem is split into a ray-based sample selection on a per-scanline basis and a backward algorithm which is based on the concept of normalized convolution. We introduce an adaptive derivation of time-domain interpo...     »
