Accurate measurement of microbubble response to ultrasound with a diagnostic ultrasound scanner
(2015)Ultrasound and microbubbles are often used to enhance drug delivery and the suggested mechanisms are extravasation and sonoporation. Drug delivery schemes with ultrasound and microbubbles at both low and high acoustic ...

Automatic respiratory gating for perfusion quantification of DCEUS
(2013)A novel automatic respiratory gating (ARG) algorithm for ultrasound is presented. The ARG algorithm was applied on dual contrast imaging (contrast/tissue) loops in order to remove respiratory motion artifacts from dynamic ...

Article
The effect of the phase of transmission on contrast agent echoes
(1998)Ultrasound contrast agents consist of a gas bubble, encapsulated by a shell for stabilization. The shell dampens the fluctuations in the bubble radius when insonified. The detection of contrast microbubbles during a medical ...

Harmonic generation with a dual frequency pulse
(2013)Nonlinear imaging was utilized in commercial ultrasound systems over the last 15 years offering major advantages in many clinical applications. In this work, pulsing schemes (pulse inversion, power modulated pulse inversion ...

Investigation of the Relationship of Nonlinear Backscattered Ultrasound Intensity with Microbubble Concentration at Low MI
(2010)Abstract: The aim of this study was to measure the relationship of image intensity with contrast agent concentration. In vitro experiments were performed with a flow phantom and a sulphur hexafluoride filled microbubble ...

Polymeric theranostics: Using polymer-based systems for simultaneous imaging and therapy
(2013)Polymer-based nanomedicine is a large and fast growing field. Polymer-based systems have been extensively used as therapeutic carriers as well as bioimaging agents for example in tumour diagnosis. However, fewer polymeric ...
