  1. 1. Probing Charm Production with Three-Particle Correlations in pp Collisions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Kim Haupt; [2023]
    Keywords : pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

    Abstract : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. READ MORE

  3. 2. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    University essay from

    Author : Ali Amena Hussain; [2022-03-09]
    Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Abstract : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

  4. 3. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Elias Nilsson; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. READ MORE

  5. 4. Automatic Calibration of Camera Parameters : A Steppingstone to Analysing Videos

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Wilma Hallén; [2022]
    Keywords : Smartphone; Video stabilisation; Calibration;

    Abstract : The smartphone is commonly used for image and video capture. Due to the lightweight of the smartphone, small handshakes are noticeable in recorded videos. The image sensors in smartphones are typically CMOS, which introduces rolling shutter artefacts. Stabilisation is introduced to minimise the effects of the camera movement and artefacts. READ MORE

  6. 5. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kani Yara; [2022]
    Keywords : B-mode; Localization; Microbubbles; Poly-Vinyl-Alcohol; Tracking; Verasonics; B-mode; Localisering; Mikrobubblor; Poly-Vinyl-Alcohol; Spårning; Verasonics;

    Abstract : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. READ MORE
