  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

  3. 2. Cosmic Dust Detection by the Solar Orbiter Using Machine Learning

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Joar Lönngren; Ludwig Tiston; [2023]
    Keywords : Machine Learning; Neural Network; Cosmic Dust; Solar Orbiter; Space Physics; Space Dust;

    Abstract : This project aims to investigate neural network systems as an effective tool for the in-space captured dust impact signal detection. Cosmic dust is the nanometre to micrometre fine-sized particles that exist in the interplanetary region. They originate from comets, asteroids, the planets and their moons and rings, or even the interstellar region. READ MORE

  4. 3. Quantum mechanical modelling and electrochemical stability of sodium based glassy electrolyte for all-solid-state batteries

    University essay from KTH/Materialvetenskap

    Author : Carolina Falk; Linnéa Johansson; [2022]

    Abstract : Increasing energy demand draws attention to new materials for improving current energy storage technologies. Particular interest is directed at solid state batteries and glass Na3ClO electrolyte is a promising candidate. READ MORE

  5. 4. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

    Author : Amanda Eriksson; [2021]
    Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

    Abstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE

  6. 5. Semi-Supervised Learning for Predicting Biochemical Properties

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Travis Persson; [2021]
    Keywords : ;

    Abstract : The predictive performance of supervised learning methods relies on large amounts of labeled data. Data sets used in Quantitative Structure Activity Relationship modeling often contain a limited amount of labeled data, while unlabeled data is abundant. READ MORE
