Large-Scale Simulation of Realistic Cardiac Ultrasound Data With Clinical Appearance: Methodology and Open-Access Database

Autor: Nitin Burman, Claudia Alessandra Manetti, Sophie V. Heymans, Marcus Ingram, Joost Lumens, Jan D'Hooge

Publikováno v: IEEE Access, Vol 12, Pp 117040-117055 (2024)

Cardiac ultrasound imaging is widely used in the clinical setting. Deep learning algorithms have shown increased potential in automating routine clinical tasks for improved diagnosis and prognosis. However, the lack of large and diverse training data

A Preliminary Investigation of Radiation-Sensitive Ultrasound Contrast Agents for Photon Dosimetry

Autor: Bram Carlier, Sophie V. Heymans, Sjoerd Nooijens, Gonzalo Collado-Lara, Yosra Toumia, Laurence Delombaerde, Gaio Paradossi, Jan D’hooge, Koen Van Den Abeele, Edmond Sterpin, Uwe Himmelreich

Publikováno v: Pharmaceuticals, Vol 17, Iss 5, p 629 (2024)

Radiotherapy treatment plans have become highly conformal, posing additional constraints on the accuracy of treatment delivery. Here, we explore the use of radiation-sensitive ultrasound contrast agents (superheated phase-change nanodroplets) as dosi

Ultrasound-assisted carbon ion dosimetry and range measurement using injectable polymer-shelled phase-change nanodroplets: in vitro study

Autor: Yosra Toumia, Marco Pullia, Fabio Domenici, Angelica Facoetti, Michele Ferrarini, Sophie V. Heymans, Bram Carlier, Koen Van Den Abeele, Edmond Sterpin, Jan D’hooge, Emiliano D’Agostino, Gaio Paradossi

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-13 (2022)

Abstract Methods allowing for in situ dosimetry and range verification are essential in radiotherapy to reduce the safety margins required to account for uncertainties introduced in the entire treatment workflow. This study suggests a non-invasive do

Single-shot attenuation coefficient estimation for ultrasound contrast agents

Autor: Jasleen Birdi, Sophie V. Heymans, Gonzalo Collado-Lara, Koen Van Den Abeele, Jan D’hooge, Alexander Bertrand

Publikováno v: Frontiers in Physics, Vol 10 (2022)

Ultrasound contrast agents (UCAs) have broadened the scope of ultrasound imaging and therapeutic applications. One of the parameters of interest when measuring the response of UCAs to ultrasound is their frequency-dependent attenuation coefficient. T

Passive Ultrasound Localization Microscopy of nanodroplet vaporizations during proton irradiation

Autor: Sophie V. Heymans, Gonzalo Collado-Lara, Marta Rovituso, Hendrik J. Vos, Jan D'hooge, Nico De Jong, Koen Van Den Abeele

Superheated nanodroplets (NDs) were recently proposed for in vivo proton range verification, owing to their ability to vaporize into echogenic microbubbles (MBs) upon exposure to ionizing radiation. In a previous publication, vaporization events were
