Automated estimation of mitral annular plane systolic excursion by artificial intelligence from 3D ultrasound recordings
Tasken, Anders Austlid; Berg, Erik Andreas Rye; Grenne, Bjørnar Leangen; Holte, Espen; Dalen, Håvard; Stølen, Stian Bergseng; Lindseth, Frank; Aakhus, Svend; Kiss, Gabriel Hanssen (Peer reviewed; Journal article, 2023)Perioperative monitoring of cardiac function is beneficial for early detection of cardiovascular complications. The standard of care for cardiac monitoring performed by trained cardiologists and anesthesiologists involves ... -
Automatic assessment of left ventricular function for hemodynamic monitoring using artificial intelligence and transesophageal echocardiography
Yu, Jinyang; Tasken, Anders Austlid; Flade, Hans Martin; Skogvoll, Eirik; Berg, Erik Andreas Rye; Grenne, Bjørnar Leangen; Rimehaug, Audun Eskeland; Kirkeby-Garstad, Idar; Aakhus, Svend (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 Myocardial Strain Imaging in Echocardiography Using Deep Learning
Østvik, Andreas; Smistad, Erik; Espeland, Torvald; Berg, Erik Andreas Rye; Løvstakken, Lasse (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 ... -
Combining Automatic Angle Correction and 3-D Tracking Doppler for the Assessment of Aortic Stenosis Severity
Fiorentini, Stefano; Espeland, Torvald; Berg, Erik Andreas Rye; Aakhus, Svend; Torp, Hans; Avdal, Jørgen (Journal article; Peer reviewed, 2019)Aortic valve stenosis (AS) is a narrowing of the aortic valve opening, which causes increased load on the left ventricle. Untreated, this condition can eventually lead to heart failure and death. According to current ... -
Examining the educational impact of the mini-CEX: a randomised controlled study
Smeby, Susanne Skjervold; Espeland, Torvald; Berg, Erik Andreas Rye; Samstad, Eivind; Lillebo, Børge; Slørdahl, Tobias Schmidt (Journal article; Peer reviewed, 2021)Background: The purpose of this study is to evaluate the mini-Clinical Evaluation Exercise (mini-CEX) as a formative assessment tool among undergraduate medical students, in terms of student perceptions, effects on direct ... -
Fully automatic estimation of global left ventricular systolic function using deep learning in transesophageal echocardiography
Berg, Erik Andreas Rye; Tasken, Anders Austlid; Nordal, Trym; Grenne, Bjørnar Leangen; Espeland, Torvald; Garstad, Idar Kirkeby; Dalen, Håvard; Holte, Espen; Stølen, Stian Bergseng; Aakhus, Svend; Kiss, Gabriel Hanssen (Journal article, 2023)Aims To improve monitoring of cardiac function during major surgery and intensive care, we have developed a method for fully automatic estimation of mitral annular plane systolic excursion (auto-MAPSE) using deep learning ... -
Mechanical wave velocities in left ventricular walls – in healthy subjects and patients with aortic stenosis
Espeland, Torvald; Wigen, Morten Smedsrud; Dalen, Håvard; Berg, Erik Andreas Rye; Hammer, Tommy Arild; Salles, Sebastien Andre Roger; Løvstakken, Lasse; Amundsen, Brage H.; Aakhus, Svend (Peer reviewed; Journal article, 2023)Background Mechanical wave velocity (MWV) measurement is a promising method for evaluating myocardial stiffness, because these velocities are higher in patients with myocardial disease. Objectives Using high frame ... -
Moving ferromagnetic objects distorting cardiac magnetic resonance imaging

Quantification of Flow Rates and Flow Volumes in Valve Regurgitation Using 3-D High Frame-Rate Ultrasound
Fiorentini, Stefano; Berg, Erik Andreas Rye; Torp, Hans Garman; Aakhus, Svend; Avdal, Jørgen (Journal article; Peer reviewed, 2023)Valve regurgitation is a cardiac condition caused by the incomplete closure of a cardiac valve. Untreated, this condition may result in cardiac failure. Regular monitoring of this condition is essential in guiding the ... -
Quantifying Valve Regurgitation Using 3-D Doppler Ultrasound Images and Deep Learning
Wifstad, Sigurd Vangen; Løvstakken, Lasse; Avdal, Jørgen; Berg, Erik Andreas Rye; Torp, Hans; Grenne, Bjørnar; Fiorentini, Stefano (Peer reviewed; Journal article, 2022)Accurate quantification of cardiac valve regurgitation jets is fundamental for guiding treatment. Cardiac ultrasound is the preferred diagnostic tool, but current methods for measuring the regurgitant volume are limited ... -
Studying the Origin of Reverberation Clutter in Echocardiography: In Vitro Experiments and In Vivo Demonstrations
Fatemi, Ali; Berg, Erik Andreas Rye; Rodriguez-Molares, Alfonso (Peer reviewed; Journal article, 2019)Clutter in echocardiography hinders the visualization of the heart and reduces the diagnostic value of the images. The detailed mechanisms that generate clutter are, however, not well understood. We present five different ... -
A Very Large Cardiac Channel Data Database (VLCD) Used to Evaluate Global Image Coherence (GIC) as an In Vivo Image Quality Metric
Rindal, Ole Marius Hoel; Bjåstad, Tore Grüner; Espeland, Torvald; Berg, Erik Andreas Rye; Måsøy, Svein-Erik (Peer reviewed; Journal article, 2023)Ultrasound image quality is of utmost importance for a clinician to reach a correct diagnosis. Conventionally, image quality is evaluated using metrics to determine the contrast and resolution. These metrics require ...
