The vascular structure of tumors impacts diagnosis, prognosis and drug response; however, imaging methods to analyse this important feature have been hindered by spatial resolution limitations. Here the authors present a tool called motion model ultr

Super-resolution imaging methods promote tissue characterization beyond the spatial resolution limits of the devices and bridge the gap between histopathological analysis and non-invasive imaging. Here, we introduce motion model ultrasound localizati

The imaging of microvessels and the quantification of their blood flow is of particular interest in the characterization of tumor vasculature. The imaging resolution (50–200 $\upmu {\bf m}$ ) of high-frequency ultrasound (US) (20–50 MHz) is not s

Reconstruction of flow velocity inside vessels by tracking single microbubbles with an MCMC data association algorithm

Autor: Dimitri Ackermann, Georg Schmitz

Publikováno v: 2013 IEEE International Ultrasonics Symposium (IUS).

In this contribution, we propose a method to track single microbubbles. The aim of this method is the reconstruction of microvessels. An experiment with a vessel phantom was set up. The flow rate of a suspension (concentration 20/ml) of cyanoacrylate
