  1. 1. Limited angle reconstruction for 2D CT based on machine learning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Eric Oldgren; Knut Salomonsson; [2023]
    Keywords : CT; computed tomography; limited angle; machine learning; limited data; ill posed problem; inverse problem;

    Abstract : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

    Abstract : Computed x-ray tomography is one of the most common medical imaging modalities andas such ways of improving the images are of high relevance. Applying deep learningmethods to denoise CT images has been of particular interest in recent years. READ MORE

  4. 3. Evaluation of deep learning image reconstruction for brain- and abdominal CT - A visual grading characteristics study

    University essay from

    Author : Tuva Skarp; [2022-05-04]
    Keywords : Medical physics; CT; Computed tomography; imaging; Deep learning image reconstruction;

    Abstract : Computed tomography (CT) is a common medical imaging method today. There are different ways of reconstructing the images from a CT examination. The standard method is the filtered back projection (FBP). READ MORE

  5. 4. Isolation of the native chloroplast proteome from plant for identification of protein-metabolite interactions

    University essay from KTH/Proteinvetenskap

    Author : Linnéa Strandberg; [2021]
    Keywords : Chloroplast; metabolism; proteomics; Calvin cycle; Arabidopsis; Kloroplast; metabolism; proteomik; Calvincykel; Arabidopsis;

    Abstract : För att kunna livnära en växande population behöver avkastningen på skördar öka. En lösning på dettaär att optimera plantornas fotosyntes, vilket innefattar förbättrad koldioxidfixering. För att lyckas meddet krävs kunskap i hur reglering av nyckelproteiner i kloroplasten går till. READ MORE

  6. 5. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Monowarul Islam; Muftadi Ullah Arpon; [2020]
    Keywords : CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

    Abstract : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. READ MORE
