  1. 1. Automatic Tissue Segmentation of Volumetric CT Data of the Pelvic Region

    Master-uppsats, Linköpings universitet/Medicinsk informatik

    Författare :Julius Jeuthe; [2017]
    Nyckelord :Image segmentation; Computed tomography; Pelvic region; Threshold segmentation; Region growing; Histogram matching; Atlas segmentation; Morphon;

    Sammanfattning : Automatic segmentation of human organs allows more accurate calculation of organ doses in radiationtreatment planning, as it adds prior information about the material composition of imaged tissues. For instance, the separation of tissues into bone, adipose tissue and remaining soft tissues allows to use tabulated material compositions of those tissues. LÄS MER

  3. 2. Evaluation of 3D MRI Image Registration Methods

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Magnus Ivarsson; [2017]

    Sammanfattning : Image registration is the process of geometrically deforming a template image into a reference image. This technique is important and widely used within thefield of medical IT. The purpose could be to detect image variations, pathologicaldevelopment or in the company AMRA’s case, to quantify fat tissue in variousparts of the human body. 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. Volumetric Quantification of Metastatic Burden from SPECT/CT Images

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Hanna Carlsson; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Bone scintigraphy images are used to investigate the presence of metastases in patients with prostate cancer. An analysis of these images indicates the proportion of cancer in the bones; the Bone Scan Index (BSI). This value is an important prognostic factor used to predict the future for the patients.
