  1. 1. Generation and detection of entangled single-photon pairs

    University essay from Uppsala universitet/FREIA

    Author : Gabriella Tesfamichael Habtezion; [2024]
    Keywords : ;

    Abstract : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. READ MORE

  3. 2. Deep Learning for the prediction of RASER-MRI profiles

    University essay from Linköpings universitet/Medie- och Informationsteknik

    Author : Filip Arvidsson; Jonas Bertilson; [2023]
    Keywords : MRI; NMR; AI; Deep Learning; RASER-MRI; Media Technology; KIT; LIU; CNN; Autoencoder; Djupinlärning; Medieteknik; Magnetröntgen;

    Abstract : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. READ MORE

  4. 3. Total body perfusion imaging with 15O-water PET

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Åhlström; [2023]
    Keywords : ;

    Abstract : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. READ MORE

  5. 4. Examination of suitable material for phantoms used in photoacoustics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Malin Larsson; Klara Wahldén; [2022]
    Keywords : Photoacoustics; PIA; Center frequency spectrum; Technology and Engineering;

    Abstract : A fundamental part of modern medicine is the ability to study and analyze images, especially for diagnostic purposes. A relatively new imaging system is photoacoustics, where laser- and ultrasound technology are combined to create images in a non-invasive way. READ MORE

  6. 5. The Spatial Properties of the Beam Profile of an OPCPA

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

    Author : Mattias Bengtsson; [2019]
    Keywords : Laser; OPCPA; Imaging Spectrometer; Physics and Astronomy;

    Abstract : OPCPA stands for optical parametric chirped-pulse amplification. It is a nonlinear method for amplifying broadband laser beams. The spatial properties of the output of the laser beam depends on the amplification method itself and the broadband configuration. READ MORE
