1. 1. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fritiof Hegardt; [2022]
   Keywords : Technology and Engineering;

   Abstract : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). READ MORE

3. 2. Development of a subject specific 3D knee finite element model to estimate the effect of weight loss on cartilage biomechanics

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Julius Dahlgren; [2022]
   Keywords : biomechanics; knee; cartilage; subject-specific; finite element; FE; FEM; weight loss; osteoarthritis; Technology and Engineering;

   Abstract : Osteoarthritis (OA) is a common musculoskeletal disorder that degrades articular cartilage and is a leading cause of disability worldwide. Overweight has been considered a major risk factor of knee OA, and it is known that weight loss may reduce the risk of knee OA. READ MORE

4. 3. Reduction of Noise and Artefacts in MRIScan of Metal Implant Reconstructed by Frequency Mapping

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Pontus Wahlqvist; [2022]
   Keywords : Technology and Engineering;

   Abstract : Metal objects can cause significant artefacts in magnetic resonance imaging (MRI) scans, cause loss of signal and what is known as geometric warping. There are ways to address these problems using different MRI sequences. This project looks at a newer method of artefact correction proposed by Månsson and Morin. READ MORE

5. 4. Probing Gray Matter Microstructure in Alzheimer’s Disease using Diffusion MRI

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Teresa Scheidt; [2022]
   Keywords : Technology and Engineering;

   Abstract : Alzheimer’s disease is a neurodegenerative disease and the most common cause of dementia. Apart from an early and accurate diagnosis, the ability to track progressive changes is important for the development of disease modifying treatments. READ MORE

6. 5. Automatic Left Ventricle Segmentation of Long-Axis Cardiac MRI-Images

   University essay from Lunds universitet/Matematik LTH

   Author : Ruben Bergengrip; [2021]
   Keywords : MRI; Magnetic resonance imaging; Deep Learning; Machine learning; U-net; CNN; Semantic segmentation; Segmentation; Global longitudinal strain; GLS; strain; AV-plane displacement; AVPD; long-axis; left ventricle; LV; cardiac MRI; CMR; Image analysis; Technology and Engineering;

   Abstract : Over 30 % of all deaths worldwide are related to cardiovascular diseases and they are the leading cause of death. Therefore, research into treatment, diagnosis and prognostication of these diseases are of critical importance. One way to examine the cardiovascular system is through the use of Magnetic Resonance Imaging (MRI). READ MORE
