  1. 21. Liver contrast-enhancement on Computed tomography : a question of to be or not to be in the right phase

    University essay from Uppsala universitet/Institutionen för kirurgiska vetenskaper

    Author : Jennifer Andersson; [2020]
    Keywords : Computed tomography; contrast media; liver; contrast enhancement; datortomografi; kontrastmedel; lever; kontrastuppladdning;

    Abstract : Background: Computed tomography (CT), is commonly used imaging technique in cancer patients. In CT performed for tumour staging to detect the spread of tumours, the liver is a common place for metastases. READ MORE

  3. 22. Deep Learning-Based Identification of Ischemic Regions in Native Head CT Scans

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Maximilian Hornung; [2020]
    Keywords : ;

    Abstract : Stroke is one of the major causes of death and disability worldwide. Fast diagnosis is of critical importance for stroke treatment. In clinical routine, a non-contrast CT (NCCT) is typically acquired immediately to determine whether the stroke is ischemic or hemorrhagic and plan therapy accordingly. READ MORE

  4. 23. Iterative Reconstruction Algorithm for Phase-Contrast X-Ray Imaging

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Ahmad Sadek; Ruben Pozzi; [2020]
    Keywords : Computed tomography; Medical research; Phase-contrast imaging; Propagation-based imaging; SIRT; Iterative algorithm; Paganin’s phase-retrieval; Datortomografi; Medicinsk forskning; Faskontrastavbildning; Propagation-baserad avbildning; SIRT; Iterativ algoritm; Paganins fasåterhämtning;

    Abstract : Phase-contrast imaging (PCI) is a modality of medical x-ray imaging that can solve one of the main limitations with conventional attenuation-based imaging: the imaging of materials with low attenuation coefficients, such as soft tissues. A modality of PCI, Propagation-based phase-contrast imaging (PBI), was used in this project. READ MORE

  5. 24. Beräkning av bendensitet och benvolym vid datortomografisk helkroppsundersökning av katt : jämförelse av två metoder för beräkning samt inverkan av storlek, ålder, kön och osteoartrit

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stefan Lindén; [2020]
    Keywords : katt; bendensitet; benvolym; datortomografi; benvolym; ålder; kön; storlek; felin osteoartrit;

    Abstract : Bone volume and bone density may be affected by disease. Measurement of bone volume and bone density in cats could possibly be used as a tool in diagnosing osteoarthritis (OA), lameness and other diseases expected to affect bone density and bone volume. Measurement of bone volume is also useful when evaluating body composition. READ MORE

  6. 25. Unsupervised Feature Extraction from CT Images for Clustering of Geological Drill Core Samples

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miquel Sven Larsson Corominas; [2019]
    Keywords : ;

    Abstract : Computed tomography (CT) scanned drill cores provide a high resolution view of the internal structure and composition of the rock, which is interesting for many analysis purposes. Although, this data is very high dimensional and difficult to analyze in an automatic way. READ MORE
