1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Arthur Barakat; [2023]
   Keywords : Technology and Engineering;

   Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

3. 2. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

   University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Author : Yoseph Abraham; [2023]
   Keywords : ;

   Abstract : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). READ MORE

4. 3. 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.

5. 4. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling

   University essay from KTH/Fysik

   Author : Johanna Jacobsson; [2022]
   Keywords : computed tomography; magnetic resonance imaging; cone beam computedtomography; cartilage; osteochondral lesions; metatarsal phalangeal joint; datortomografi; magnetisk resonanstomografi; kon-datortomografi; brosk; kondrala skador; metatarsalphalangen-leden;

   Abstract : Walking without pain in the toe has a significant impact on a person’s well-being. Human mobility will be impaired in osteoarthritis of the big toe, and pain will occur during walking. By replacing the cartilage or bone injury with an individualised implant, osteochondral injuries to the knee and ankle can be treated. READ MORE

6. 5. Feasibility study of initial orbit determination with open astronomical data

   University essay from KTH/Fysik

   Author : Linn Mattsson; [2022]
   Keywords : Space situational awareness; Space surveillance and tracking; Image analyse; Streak detection algorithm; Initial orbit determination; Rymdlägesbild; Bildanalys; Algoritm för streck detektering; Initial banbestämning;

   Abstract : In this report I present a feasibility study of using open astronomical data to make Initial Orbit Determination (IOD) for Resident Space Objects (RSO) appearing as streaks in telescope images. The purpose is to contribute to Space Surveillance and Tracking (SST) for maintaining Space Situation Awareness (SSA). READ MORE
