1. 1. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sara Mineur; [2023]
   Keywords : Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

   Abstract : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. READ MORE

   Abstract : Quantitative cardiac magnetic resonance imaging (CMR) has gained traction within both the clinical and research field due to high prevalence of cardiovascular diseases. Cardiac magnetic resonance fingerprinting (cMRF) is a novel approach introduced to address the limitation associated with evaluation of multiparametric quantitative CMR. READ MORE

4. 3. Designing k-Space Filters to Improve Spatiotemporal Resolution with Sector-Wise Golden Angle (SWIG)

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Jonas Ström Seez; [2022]
   Keywords : Cardiovascular Magnetic Resonance Imaging CMR ; k-Space Filter; Sector Wise Golden-angle SWIG ; Kardiovaskulär Magnetisk Resonans Tomografi CMR ; k-rumsfilter; Sektorsvis Gyllene Vinkel SWIG ;

   Abstract : The aim of this thesis is to design and evaluate k-space weighting filters for simultaneously improving the spatial and temporal resolution of cardiovascular MRI, with the ultimate goal of improving the accuracy of quantitative flow measurements, which are important for diagnosis and follow-up of heart dysfunction. Two different k-space filters were implemented and evaluated retrospectively to already acquired data. READ MORE

5. 4. 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

6. 5. Reduction of streak artifacts in radial MRI using CycleGAN

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Amanda Ullvin; [2020]
   Keywords : MRI; Cardiovascular; CMR; Medical Imaging; Radial k-space sampling; Sub-Nyquist sampling; Golden Angle; GRASP; Compressed Sensing; Artificial Intelligence; Neural Network; Deep Learning; GAN; CycleGAN;

   Abstract : One way of reducing the examination time in magnetic resonance imaging (MRI) is to reduce the amount of raw data acquired, by performing so-called undersampling. Conventionally, MRI data is acquired line-by-line on a Cartesian grid. READ MORE
