Improved Methods for Navigated 3-D Vascular Ultrasound Imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:190, Doctoral thesis, 2014)3-D reconstruction of flow based on 2-D ultrasound images and position sensor information can be used to portray clinical information not currently available in vascular imaging. However, due to Doppler angle-dependencies ... -
Improved unsupervised physics-informed deep learning for intravoxel incoherent motion modeling and evaluation in pancreatic cancer patients
(Peer reviewed; Journal article, 2021)Purpose Earlier work showed that IVIM-NETorig, an unsupervised physics-informed deep neural network, was faster and more accurate than other state-of-the-art intravoxel-incoherent motion (IVIM) fitting approaches to ... -
Improving assessment quality in professional higher education: Could external peer review be the answer?
(Journal article; Peer reviewed, 2019)Summative assessment in professional higher education is important for student learning and making sound decisions about advancement and certification. Despite rigorous pre-test quality assurance procedures, problematic ... -
Improving Elastography using SURF Imaging for Suppression of Reverberations
(Master thesis, 2010)For some of the applications of the Second-order UltRasound Field (SURF) imaging technique, a real-time delay-estimation algorithm has been developed for estimating spatially range-varying delays in RF signals. This algorithm ... -
Improving flow detection with Doppler ultrasound in medical and oil and gas applications

Improving reproductive function in women with polycystic ovary syndrome with high-intensity interval training (IMPROV-IT): study protocol for a two-centre, three-armed randomised controlled trial.
(Journal article; Peer reviewed, 2020)Introduction Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age and the leading cause of anovulatory infertility. Women with PCOS have a 15-fold higher prevalence of infertility, ... -
In children and adolescents with temporomandibular disorder assembled with juvenile idiopathic arthritis ‑ no association were found between pain and TMJ deformities using CBCT
(Peer reviewed; Journal article, 2021)Background Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer from temporomandibular disorder (TMD). Due to this, imaging diagnosis is crucial in JIA with non-symptomatic TM joint (TMJ) involvement. ... -
In vivo 31P MRSI for metabolic profiling of human breast cancer xenografts
(Journal article; Peer reviewed, 2015)Purpose To study cancer associated with abnormal metabolism of phospholipids, of which several have been proposed as biomarkers for malignancy or to monitor response to anticancer therapy. We explored 3D 31P magnetic ... -
In vivo intracardiac vector flow imaging using phased array transducers for pediatric cardiology
(Journal article; Peer reviewed, 2017)Two-dimensional blood speckle tracking (ST) has shown promise for measuring complex flow patterns in neonatal hearts using linear arrays and high-frame-rate plane wave imaging. For general pediatric applications, however, ... -
