1. Simulating metal ct artefacts for ground truth generation in deep learning.
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : 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.

2. Emphysema Classification via Deep Learning
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : Emphysema is an incurable lung airway disease and a hallmark of Chronic Obstructive Pulmonary Disease (COPD). In recent decades, Computed Tomography (CT) has been used as a powerful tool for the detection and quantification of different diseases, including emphysema. The use of CT comes with a potential risk: ionizing radiation. LÄS MER
3. Volumetric Image Segmentation of Lizard Brains
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Accurate measurement brain region volumes are important in studying brain plasticity, which brings insight into the fundamental mechanisms in animal, memory, cognitive, and behavior research. The traditional methods of brain volume measurements are ellipsoid or histology. LÄS MER
4. Optic nerve sheath diameter semantic segmentation and feature extraction
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Traumatic brain injury (TBI) affects millions of people worldwide, leading to significant mortality and disability rates. Elevated intracranial pressure (ICP) resulting from TBI can cause severe complications and requires early detection to improve patient outcomes. LÄS MER
5. The Impact of Image Resolution on Lesion Detection in CT scans Using Machine Learning
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Identifying cancer and other diseases that cause lesions (damages or abnormalities to tissue) early is crucial to assure the best treatment. However, lesions are often missed which can cause diseases to progress to an advanced-stage of the diseases which is harder to cure. LÄS MER
