  1. 6. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Albin Lindvall; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

  3. 7. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Merel Younan; [2023]
    Keywords : SFDI; transillumination SFDI system; tissue-conserving surgeries; thin layers; tissue analysis; skin cancer;

    Abstract : This study investigates the potential of Spatial Frequency Domain Imaging (SFDI) as a non-invasive imaging technique for tissue analysis in the context of Mohs surgery, a standard procedure for skin cancer removal with margin control. The current practice of performing multiple histopathologic sections during the procedure is time-consuming and labor-intensive. READ MORE

  4. 8. Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Cornelia Säll; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. READ MORE

  5. 9. 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. 10. Preparations for photon external beam radiotherapy treatment planning of small animals

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Joanie Diha Guei; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE
