  1. 1. ATLAS-BASED SEGMENTATION OF ULTRAHIGH-RESOLUTION STRUCTURAL MR HEAD IMAGES ACQUIRED AT 7 TESLA

    University essay from

    Author : Frida Johansson; [2022-01-13]
    Keywords : Medical physics; Anatomical segmentation; Brain; MRI; 7 Tesla; Pincram; MAPER; Shape based averaging; Ultrahigh resolution;

    Abstract : Purpose: The purpose of this work was to find out how the existing brain atlases and segmentation algorithms perform when applied to ultrahigh-resolution MR brain images, acquired with a 7-Tesla scanner. Also to make adaptations to deal with the potential challenges and evaluate the quality of the anatomical segmentations of the 7- Tesla images. READ MORE

  2. 2. 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

  3. 3. Evaluation of factors that might affect the grading of heart murmurs in dogs with myxomatous mitral valve disease

    University essay from SLU/Dept. of Clinical Sciences

    Author : Emilia Horn; [2022]
    Keywords : murmur grading; grading of heart murmurs; factors impacting murmur grading; utility of murmur grading scales; myxomatous mitral valve disease; MMVD; dog;

    Abstract : Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs. The first sign of MMVD is usually a heart murmur, which most commonly is detected before clinical signs of the disease potentially develop. The preclinical period of MMVD is usually long and can be prolonged with medical treatment. READ MORE

  4. 4. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

    University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

    Author : Tova Rung; [2022]
    Keywords : Synthetic CT; Air coil;

    Abstract : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.
