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

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

  2. 2. Assessment of the Fluorescent Activities of Different Fluorescent Proteins for Potential Use as Biosensors in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Johan Davidsson; [2020]
    Keywords : Fluorescent proteins; Saccharomyces cerevisiae; Flow cytometry; CRISPR Cas9; Biosensors; Applied microbiology; Tillämpad mikrobiologi; Technology and Engineering;

    Abstract : Development of genetically modified microorganisms such as Saccharomyces cerevisiae for use as microbial cell factories to produce fine and bulk chemicals has lately proceeded very rapidly, much thanks to new gene editing methods based on a CRISPR/Cas9 system adapted from bacteria which increases the rate of genetic engineering. However, development of methods which enable fast and simple screening of the best performing strains with specific sought-after characteristics is not advancing at the same pace. READ MORE

  3. 3. Coil Sensitivity Estimation and Intensity Normalisation for Magnetic Resonance Imaging

    University essay from KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Author : Rebecka Herterich; Anna Sumarokova; [2019]
    Keywords : Image reconstruction; Magnetic Resonance Imaging; sensitivity encoding; Parallell imaging; Coil sensitivity; ISMRM raw data; Magnetresonanstomografi; känslighetskodning; bildrekonstruktion; Parallell imaging; Spolkänslighet; ISMRMRD;

    Abstract : The quest for improved efficiency in magnetic resonance imaging has motivated the development of strategies like parallel imaging where arrays of multiple receiver coils are operated simultaneously in parallel. The objective of this project was to find an estimation of phased-array coil sensitivity profiles of magnetic resonance images of the human body. READ MORE

  4. 4. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Jan Brabec; [2018]
    Keywords : dMRI; diffusion magnetic resonance; axonal trajectory; axonal geometry; undulations; modeling; axons; inverse problem; diffusion spectrum; time-dependent diffusion; Physics and Astronomy;

    Abstract : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. READ MORE

  5. 5. Fabrication and characterization of a blood-brain barrier on-a-chip for electrical characterization of cells

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Rebecka Sörensen; [2018]
    Keywords : ;

    Abstract : The blood-brain barrier (BBB) is crucial to maintain brainhomeostasis and prevent toxic substances from entering the brain.Endothelial cells (EC) are essential for the BBB and in this thesistwo different BBB-on-chips were designed for electricalcharacterization of immortalized mouse EC (bEnd3).
