A Scientific Tool for Real-time Acquisition and Analysis of Cardiovascular Measurements: Including ultrasound and other physiological data sources
Wigen, Morten Smedsrud (Master thesis, 2013)En programvare for studier av karsystemet, for både eksperimentelle og kliniske forsøk, skal utvikles i denne oppgaven. Data fra både ultralyd og andre fysiologiske kilder, som trykk, blodstrøm og volum, skal kunne mottas ... -
Abnormal Colon Polyp Image Synthesis Using Conditional Adversarial Networks for Improved Detection Performance
Shin, Younghak; Qadir, Hemin Ali; Balasingham, Ilangko (Journal article; Peer reviewed, 2018)One of the major obstacles in automatic polyp detection during colonoscopy is the lack of labeled polyp training images. In this paper, we propose a framework of conditional adversarial networks to increase the number of ... -
Achieving Fair Spectrum Allocation and Reduced Spectrum Handoff in Wireless Sensor Networks: Modeling via Biobjective Optimization
Byun, Sang-Seon; Kansanen, Kimmo; Balasingham, Ilangko; Gil, Joon-Min (Journal article; Peer reviewed, 2014)This paper considers the problem of centralized spectrum allocations in wireless sensor networks towards the following goals: (1) maximizing fairness, (2) reflecting the priority among sensor data, and (3) avoiding unnecessary ... -
Ambient-light Photoplethysmography: - How can I tell your pulse from looking at your face?
Rustand, Åsmund (Master thesis, 2012)This thesis is an attempt to explore certain aspects of the subject called non-contact, ambient-light photoplethysmography, where we hope to reveal benecialproperties the technique may have. We have a clear focus on technical ... -
An Investigation of Stochastic Market Equilibrium in Cognitive Radio Networks
Byun, Sang-Seon; Vasilakos, Athanasios; Balasingham, Ilangko (Journal article; Peer reviewed, 2010)In this letter, we model a cognitive radio network as an interference market where each primary user (PU) and secondary user (SU) are price-taking interference offerers and purchasers, respectively. We consider stochastic ... -
An Optimized Cross-Layer Protocol For Patient Confined Wireless Network
Vo, Loc Tan (Master thesis, 2007)Mobility and freedom are two driving forces for research in wireless sensor networks. Recent advances in hardware development, offering low-cost, low-power sensor devices open up for an exciting research field where only ... -
Analysis of low Frequency content from the Circulatory System
Stenerud, Kristian L (Master thesis, 2016)This thesis has investigated the low frequency content from the cardiovascular system. Three different signals; heart rate variability(HRV), blood pressure(BP) and a flow signal of the blood(Laser doppler flow, LDF) all ... -
Automatic adaptation of information in electronic patient records for patients
Ivanova, Elena (Master thesis, 2006)In this work we present results of research, design and implementation of prototype system aimed at the task of automatically identifying and explaining difficult medical words in Electronic Patient Records. A patient ... -
Automatic colon polyp detection using region based deep CNN and post learning approaches
Shin, Younghak; Qadir, Hemin Ali Qadir; Aabakken, Lars; Bergsland, Jacob; Balasingham, Ilangko (Journal article; Peer reviewed, 2018)Automatic image detection of colonic polyps is still an unsolved problem due to the large variation of polyps in terms of shape, texture, size, and color, and the existence of various polyp-like mimics during colonoscopy. ... -
Automatic Extraction of Doppler Parameters for the Assessment of Fetal and Maternal Health
Heyer, Agnes Margrethe (Master thesis, 2014)In developing countries, the availability of personnel with training in the use of ultrasound devices and the availability of conventional ultrasound equipment may be very limited. It is therefore beneficial to automate ... -
Automatic polyp frame screening using patch based combined feature and dictionary learning
Shin, Younghak; Balasingham, Ilangko (Journal article; Peer reviewed, 2018)Polyps in the colon can potentially become malignant cancer tissues where early detection and removal lead to high survival rate. Certain types of polyps can be difficult to detect even for highly trained physicians. ... -
Automatisk sporing av Dopplerspektrum
Vartdal, Gaute (Master thesis, 2011)En rekke verdier i hjertet som man normalt finner ved invasiv undersøkelse med kateter, kan med stor nøyaktighet beregnes ut fra hastigher man finner ved Dopplerultralyd. Eksempelvis er trykket i hjertekammere og blodårer ... -
Basal Strain Estimation in Transesophageal Echocardiography using Unsupervised Deep Learning
Haukom, Torjus (Master thesis, 2019)Pasienter med behov for hjertekirurgi løper en risiko for alvorlige komplikasjoner under og etter inngrepet, og blir derfor overvåket gjennom den perioperative perioden. Ekkokardiografisk evaluering kan være en viktig del ... -
