1. Bilddiagnostik av barn ochungdomar vid skolios : En jämförande litteraturstudie mellan konventionell röntgen, datortomografi och entrepreneurial operating system
Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaperSammanfattning : Bakgrund: Konventionell röntgen, datortomografi (DT) och entrepreneurial operating system (EOS) är tre radiologiska undersökningsmetoder som kan användas för bilddiagnostik vid skolios av barn och ungdomar. Undersökningarna kan genomföras i en liggande eller stående positionering vid bedömning av ryggradens deformation. LÄS MER
2. 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.

3. Fine-Tuning Parameters in CT
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Computed tomography (CT) is a medical imaging technique that usesX-rays to obtain a reconstruction of an object. The term acquisition ge-ometry refers to the arrangement of imaging sensors and the X-ray sourceas well as the procedure used for data collection. 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. Improving proton therapy planning with photon-counting spectral computed tomography
Master-uppsats, KTH/FysikSammanfattning : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.
