Automatic analysis in echocardiography using machine learning
(Doctoral theses at NTNU, 2021:230, Doctoral thesis, 2021)Echocardiography is the cornerstone of modern cardiac imaging due to its availability, low cost and real-time functionality. The modality has enabled sophisticated non-invasive evaluation of the hearts morphophysiology, ... -
Automatic assessment of left ventricular function for hemodynamic monitoring using artificial intelligence and transesophageal echocardiography
(Peer reviewed; Journal article, 2024)We have developed a method to automatically assess LV function by measuring mitral annular plane systolic excursion (MAPSE) using artificial intelligence and transesophageal echocardiography (autoMAPSE). Our aim was to ... -
Automatic Classification of Sub-Techniques in Classical Cross-Country Skiing Using a Machine Learning Algorithm on Micro-Sensor Data
(Journal article; Peer reviewed, 2018)The automatic classification of sub-techniques in classical cross-country skiing provides unique possibilities for analyzing the biomechanical aspects of outdoor skiing. This is currently possible due to the miniaturization ... -
Automatic Detection and Measurement of Fetal Biparietal Diameter and Femur Length — Feasibility on a Portable Ultrasound Device
(Journal article, 2017)An automatic method able to recognize a presented section through the biparietal plane of the fetal head and a section through the fetal femur in ultrasound images is developed. Once the correct anatomical section for ... -
Automatic interpretation of cement evaluation logs from cased boreholes using supervised deep neural networks
(Peer reviewed; Journal article, 2020)The integrity of cement in cased boreholes is typically evaluated using well logging. However, well logging results are complex and can be ambiguous, and decisions associated with significant risks may be taken based on ... -
Automatic Intraoperative Correction of Brain Shift for Accurate Neuronavigation
(Journal article; Peer reviewed, 2018)Background Unreliable neuronavigation owing to inaccurate patient-to-image registration and brain shift is a major problem in conventional magnetic resonance imaging–guided neurosurgery. We performed a prospective ... -
Automatic intraoperative estimation of blood flow direction during neurosurgical interventions
(Journal article; Peer reviewed, 2018)Purpose In neurosurgery, reliable information about blood vessel anatomy and flow direction is important to identify, characterize, and avoid damage to the vasculature. Due to ultrasound Doppler angle dependencies and the ... -
Automatic measurements of left ventricular volumes and ejection fraction by artificial intelligence: clinical validation in real time and large databases
(Peer reviewed; Journal article, 2023)Aims Echocardiography is a cornerstone in cardiac imaging, and left ventricular (LV) ejection fraction (EF) is a key parameter for patient management. Recent advances in artificial intelligence (AI) have enabled fully ... -
Automatic measurements of mitral annular motion indices
(Doctoral theses at NTNU;2020:4, Doctoral thesis, 2020) -
Automatic measurements of mitral annular plane systolic excursion and velocities to detect left ventricular dysfunction
(Journal article; Peer reviewed, 2018)The purpose of the study described here was to evaluate an automatic algorithm for detection of left ventricular dysfunction, based on measurements of mitral annular motion indices from color tissue Doppler apical four-chamber ... -
Automatic Myocardial Strain Imaging in Echocardiography Using Deep Learning
(Journal article; Peer reviewed, 2018)Recent studies in the field of deep learning suggest that motion estimation can be treated as a learnable problem. In this paper we propose a pipeline for functional imaging in echocardiography consisting of four central ... -
Automatic quantification of left ventricular function by medical students using ultrasound
(Peer reviewed; Journal article, 2020)Background Automatic analyses of echocardiograms may support inexperienced users in quantifying left ventricular (LV) function. We have developed an algorithm for fully automatic measurements of mitral annular plane ... -
Autonomi hos den psykiatriske pasienten - et spørsmål om etikk i sykepleie
(Bachelor thesis, 2023)Bakgrunn: Pasienter med alvorlige psykiske lidelser lever i gjennomsnitt 10-15 år kortere enn den gjennomsnittlige nordmann. Det er en rekke potensielle årsaker for dette, slik som rusproblematikk, men en utfordring som ... -
Autonomi, medvirkning og terminal sykdom
(Bachelor thesis, 2021)Hensikt: Hensikten med oppgaven er å bli faglig sterkere i forhold til ivaretakelse av pasientens autonomi og medvirkning i beslutningsprosesser vedrørende livsforlengende behandling og palliativ omsorg. Vi ønsker også å ... -
Autonomic activation and muscle activity in relation to musculoskeletal pain
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:202, Doctoral thesis, 2007)Background and objectives: Musculoskeletal pain is frequent and the most common cause of sick leave in Norway. Although chronic musculoskeletal pain is conceived to be related to social or mental stress, the mechanism for ... -
Autonomic and muscular responses and recovery to one-hour laboratory mental stress in healthy subjects
(Journal article; Peer reviewed, 2007-08-14)Background: Stress is a risk factor for musculoskeletal pain. We wanted to explore stress related physiology in healthy subjects in order to gain insight into mechanisms of pain development which may relate to the ... -
Autophagy as a Survival Mechanism or a Cause of Disease
(Doctoral thesis at NTNU;2016:52, Doctoral thesis, 2016)Proper turnover of cellular components is crucial for all cells. If damaged or excessive content in the cell is not removed at a sufficient pace, normal cell functions may be compromised. The same may occur if the ... -
Autophagy signaling in skeletal muscle of infarcted rats
(Journal article; Peer reviewed, 2014)Background: Heart failure (HF)-induced skeletal muscle atrophy is often associated to exercise intolerance and poor prognosis. Better understanding of the molecular mechanisms underlying HF-induced muscle atrophy may ... -
