3D Speckle-Tracking: Sub-voxel Techniques and Tracking Accuracy
Bostad, Ingvild Haraldsen (Master thesis, 2006)Speckle tracking is a method that is useful for examining myocardial function. The method allows the cardiologist examine the left ventricular wall function when there are indications of a myocardial infarction. The method ... -
3D visualisering av lekkasje i hjerteklaff
Horne, Øyvind (Master thesis, 2006)For å kunne gjøre en god gradering av en mitralinsuffisiens er det viktig med en nøyaktig presentasjon av tilbakestrømningen i fargedoppler. Presentasjon av data må også gjøres kjapt for å kunne holde følge med hjertets ... -
A framework for the simulation and validation of acoustic fields from medical ultrasound transducers
Bakstad, Ole (Master thesis, 2012)The unified simulation framework for medical ultrasound, FieldSim, cur- rently supports linear and non-linear simulations by using Field II and Aber- sim, respectively. In this thesis the quasi-linear simulation tool, ... -
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 Intima-Lumen detection in Cardiovascular Ultrasound.
Edvardsen, Kristin Holm (Master thesis, 2006)The main goal in this thesis has been to develop an algorithm that robustly identifies the Carotid artery wall boundaries throughout a heart cycle in an ultrasound image. An existing automatic vessel detection algorithm ... -
Coded Excitation in Color Flow Imaging
Holje, Jostein (Master thesis, 2007) -
Deteksjon av luftembolier i hjernen hos nyfødte ved hjelp av ultralyd Doppler
Kjelsaas, Karoline (Master thesis, 2020)Når spedbarn er født med en form for hjertefeil kan kateterintervensjon eller hjerte-kirurgi hjelpe. Dette kan føre til at luftbobler, eller embolier, kommer inn i blodstrømmen. Årsaken er for det meste ukjent, men ... -
Modeling and monitoring cerebral blood flow in premature infants with patent ductus arteriosus using ultrasound Doppler technique
Tran, Alex (Master thesis, 2018)The aim of this thesis was to simulate cerebral bloodflow of premature infants with patent ductus arteriosus, using a lumped model. A linear Windkessel-3 model with constant peripheral resistance, and a non-linear Windkessel-3 ... -
Modeling of Peripheral Resistance in the Microvasculature for Diabetic Patients with Ultrasound Doppler Technique
Wisløff, Anna Karoline (Master thesis, 2018)Diabetes is a growing health problem worldwide and involves long-term complications. Microangiopathy is one of the main issues associated with diabetes and is a condition that is difficult to detect. The aim of this project ... -
Ultrasound Contrast Imaging - Improved Tissue Suppression in Amplitude Modulation
Hofstad, Erlend Fagertun (Master thesis, 2006)The ability to image myocardial perfusion is very important in order to detect coronary diseases. GE Vingmed Ultrasound uses contrast agent in combination with a pulse inversion (PI) technique to do the imaging. But this ...
