6. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling
University essay from KTH/FysikAbstract : 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

7. Preparations for photon external beam radiotherapy treatment planning of small animals
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

8. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES
University essay fromAbstract : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. READ MORE

9. Domain Adaptation for Combined CT and CBCT Deep Learning Segmentation
University essay from Lunds universitet/Matematik LTHAbstract : Computed tomography (CT) segmentation models are frequently used within radiotherapy treatment planning, but similar models are not available to the related imaging modality cone beam computed tomography (CBCT) due to the scarcity of labeled data from this domain. Such models could have multiple clinical applications whereby it is of interest to study whether the CT segmentation models can be adapted to generalize to the CBCT domain. READ MORE

10. Implementation of the Weighted Filtered Backprojection Algorithm in the Dual-Energy Iterative Algorithm DIRA-3D
University essay from Linköpings universitet/Institutionen för systemteknikAbstract : DIRA-3D is an iterative model-based reconstruction method for dual-energy helical CT whose goal is to determine the material composition of the patient from accurate linear attenuation coefficients (LACs). Possible applications are, for example, to aid in calculations of radiation transport and dose calculations in brachytherapy with low energy photons, and in proton therapy. READ MORE
