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

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

   Abstract : 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. READ MORE

3. 2. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : David Rydgård; [2023]
   Keywords : Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

   Abstract : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. READ MORE

4. 3. X-Ray Tomography on Intestine Samples

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

   Author : Julia Rogalinski; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. READ MORE

5. 4. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

   University essay from

   Author : Jesper Brovall; [2022-01-13]
   Keywords : Medical physics; Dosimetry; MRI; Radiation therapy;

   Abstract : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. READ MORE

6. 5. Quantum state tomography of attosecond electron wavepackets

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

   Author : Ron Demjaha; [2022]
   Keywords : quantum physics; quantum state tomography; atomic physics; quantum optics; density matrix; entanglement; state mixing; fano resonances; two-photon absorption; Physics and Astronomy;

   Abstract : In this master thesis, a broad theoretical description is done of a novel quantum state tomography protocol called KRAKEN. This protocol is meant for the determination of the density matrix of an electronic state created by absorption of XUV radiation in the vicinity of a Fano resonance. At first, a description of the KRAKEN protocol is provided. READ MORE
