16. 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

17. Pre-planning of Individualized Ankle Implants Based on Computed Tomography - Automated Segmentation and Optimization of Acquisition Parameters
University essay from KTH/FysikAbstract : The structure of the ankle joint complex creates an ideal balance between mobility and stability, which enables gait. If a lesion emerges in the ankle joint complex, the anatomical structure is altered, which may disturb mobility and stability and cause intense pain. READ MORE

18. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments
University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologiAbstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE

20. Automated 3D Bone Segmentation using Deep Learning in Scoliosis
University essay from Lunds universitet/Matematik LTHAbstract : Background: Scoliosis is a condition where a person's spine is curved and rotated in three dimensions. In severe cases, surgery is needed to straighten the spine. Before such complex procedures, meticulous planning is needed. By performing a CT-scan, images of the spine can be acquired. READ MORE
