  1. 16. Finite Element Model of Mechanical Imaging of the Breast for OpenVCT Software Platform

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Rebecca Axelsson; [2020]
    Keywords : Technology and Engineering;

    Abstract : Styvhetsförändringar i bröstvävnad är ofta kopplade till en patologisk förändring. Vissa cancertyper som infiltererande duktalt carcinom kan vara åtta gånger så styv som fettvävnaden runt omkring. READ MORE

  3. 17. Assessment of mammography screening using clinical and virtual data

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Hanna Tomic; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Aim: Virtual clinical trials (VCT) in medical imaging can be used to predict the outcome of clinical trials, by simulating anatomy, imaging methods and image interpretation. VCTs could reduce the cost and duration of clinical trials and their dependence on available patients. READ MORE

  4. 18. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging

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

    Author : Chen Xu; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. READ MORE

  5. 19. Characterization of breast tomosynthesis systems: A comparison and optimization

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thanh Tra Pham; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Aim: The aim of the study is to characterize the dependency of image quality on absorbed dose for two breast tomosynthesis (BT) systems, GE Senographe Pristina and Siemens Mammomat Inspiration and compare the systems. The image quality was evaluated by different parameters such as: in-plane and in-depth spatial resolution, artifact spread function (ASF) and signal-difference-to-noise ratio (SDNR). READ MORE

  6. 20. Correction of Radial Sampling Trajectories by Modeling Nominal Gradient Waveforms and Convolving with Gradient Impulse Response Function

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Max Kim; Adham Belbaisi; [2019]
    Keywords : Magnetic resonance imaging; MRI; gradient waveforms; radial sampling; gradient imperfections; gradient impulse response function; GIRF; Magnetresonanstomografi; MRI; gradient vågformer; radiell sampling; gradient imperfektioner; gradient impulsresponsfunktion; GIRF;

    Abstract : There are several reasons for using non-Cartesian k-space sampling methods in Magnetic Resonance Imaging (MRI). Such a method is radial sampling, which includes the advantage of continuous coverage of the k-space center which results in higher robustness to motion. READ MORE
