  1. 1. Development and evaluation of an inter-subject image registration method for body composition analysis for three slice CT images

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Hugo Dahlberg; [2022]
    Keywords : Medical imaging; Image registration; SCAPIS;

    Abstract : Over 30 000 liver, abdomen, and thigh slices have been acquired by computed tomography for the SCAPIS and IGT study. To utilise the full potential of the large cohort and enable statistical pixel-wise body composition analysis and visualisation of associations with other biomarkers, a point-to-point correspondence between the scans is needed.

  2. 2. Quantification and Detection of Motion Artifacts in Laser Speckle Contrast Imaging

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

    Author : Dennis Amphan; [2022]
    Keywords : Laser speckle contrast imaging; Image registration; Motion artifacts; Detection;

    Abstract : Laser speckle contrast imaging (LSCI) is a non-invasive method for assessment of microcirculatory blood flow. The technique is based on analysis of speckle patterns to build 2D maps of perfusion with high spatial and temporal resolution. READ MORE

  3. 3. 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.

  4. 4. Voxel-wise Longitudinal Analysis of Weight Gain from Different Dietary Fats using Image Registration-Based "Imiomics" Analysis

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Vendela Andersson; [2022]
    Keywords : Image registration; Imiomics; Radiology; Magnetic Resonance Imaging;

    Abstract : There is an emerging global epidemic of obesity and related complications, such as type 2diabetes (T2D). Alterations in body composition (adipose tissue, muscle volume and fatcontents) are known to be associated with an increased metabolic risk. Understanding of theunderlying mechanisms is key for development of novel intervention strategies. READ MORE
