1. 1. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :Love Kildetoft; [2024]
   Nyckelord :Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

   Sammanfattning : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. LÄS MER

3. 2. Evaluating image analysis techniques for ultrasound optical tomography in breast tissue

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Henrik von Friesendorff; [2023]
   Nyckelord :ultrasound optical tomography; Monte Carlo light simulation; image reconstruction; Technology and Engineering;

   Sammanfattning : Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging. LÄS MER

4. 3. Characterization of neutron detection efficiency in a liquid organic scintillator

   Kandidat-uppsats,

   Författare :Ebba Wargh; Nadine Tabeshnia; [2023]
   Nyckelord :;

   Sammanfattning : Neutron detectors in the form of liquid organic scintillators are widely used for nuclear disarmament purposes. The main purpose of this thesis is to characterize the neutron detection efficiency of the organic liquid scintillator EJ-309 using Monte Carlo based simulations in the simulation program Geant4.

5. 4. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Jaida Raffelsberger; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".

7. 5. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Johan Leygonie; [2021]
   Nyckelord :QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

   Sammanfattning : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. LÄS MER
