Abdominal motion tracking with free-breathing XD-GRASP acquisitions using spatio-temporal geodesic trajectories
Correction to: Abdominal motion tracking with free‑breathing XD‑GRASP acquisitions using spatio‑temporal geodesic trajectories
(Springer, 2022-01-14)Free-breathing external beam radiotherapy remains challenging due to the complex elastic or irregular motion of abdominal organs, as imaging moving organs leads to the creation of motion blurring artifacts. In this paper, we propose a radial-based MRI ... -
The added value of quantitative ultrasound to shear-wave elastography for assessment of steatohepatitis in a rat model
(Institute of electrical and electronics engineers, 2019-12-08)Non-alcoholic fatty liver disease is a highly prevalent condition, which may progress to non-alcoholic steatohepatitis (NASH), an advanced form found in 3 to 5% of the population. As liver biopsy is invasive, there is a need for a non-invasive technique ... -
