  1. 1. Anatomical segmentation of the human brain: comparative assessment of two automatic methods

    Master-uppsats,

    Författare :Carl von Dorrien; [2023-08-22]
    Nyckelord :Medical physics; MAPER; FreeSurfer; FastSurfer; Automatic brain segmentation; MRI; Deep Neural Network; Brain;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is a robust and versatile imaging modality and an integral component of a lot of studies, especially when performing quantitative analysis. MRI is the preferred method of imaging the brain because of its excellent soft tissue contrast. LÄS MER

  3. 2. MULTI-CENTER QUANTITATIVE MEASUREMENT OF T1 ANDT2 RELAXATION TIMES IN THE RAT BRAIN

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tristan DERUELLE; [2018]
    Nyckelord :MRI; Relaxation Times; T1; T2; Rat; Brain; Quantitative; Multi-center;

    Sammanfattning : This project revolves around the measurement of T1 and T2 relaxation times in the ratbrain, in a multi-center way. That is to say, elaborate an efficient protocol to calculate highresolution 3D map of the brain. This protocol should be applied in different centers andreturn similar results. LÄS MER

  4. 3. Automatic Detection of Anatomical Landmarks in Three-Dimensional MRI

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Hannes Järrendahl; [2016]
    Nyckelord :Quantitative 3D MRI; Machine learning; Medical image processing; Morphon image registration; 3D Haar features; Random regression forests;

    Sammanfattning : Detection and positioning of anatomical landmarks, also called points of interest(POI), is often a concept of interest in medical image processing. Different measures or automatic image analyzes are often directly based upon positions of such points, e.g. in organ segmentation or tissue quantification. LÄS MER

  5. 4. Interactive segmentation of abdominal organs from 3D CT and MRI images

    Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Olof Hansson; [2010]
    Nyckelord :;

    Sammanfattning : Within the medical field, image segmentation is an important tool which can be used by radiologists and surgeons who want quantitative measurements of a lesion or organ. To be clinically useful, the tool has to be fast and easy to use. LÄS MER
