BACKGROUND: Because of superior soft tissue contrast, the use of magnetic resonance imaging (MRI) as a complement to computed tomography (CT) in the target definition procedure for radiotherapy is increasing. To keep the workflow simple and cost effe

The primary aim of the present work was to analyze the effects of varying scatter-to-primary ratios on the appearance of simulated nodules in chest tomosynthesis section images. Monte Carlo simulations of the chest tomosynthesis system GE Definium 80

Background Semi-automated segmentation using deformable registration of atlases consisting of pre-segmented patient images can facilitate the tedious task of delineating structures and organs in patients subjected to radiotherapy planning. However, a

Det har tidigare uppmärksammats att magnetfältsnivåerna kan vara relativt höga i kuvöser, framförallt på grund av den värmebädd som barnet ligger på. I epidemiologiska studier av barnleukemi och association till magnetfältsexponering har m

Introduction: Magnetic resonance (MR) imaging is one of the most important diagnostic tools in modern medicine. Compared to other imaging modalities, it provides superior soft tissue contrast of all parts of the body and it is considered to be safe f

Radiation therapy is an important method to treat cancer with the aim to deliver as high doses as reasonably achievable to the tumor while protecting the surrounding healthy tissue and organs at risk, OARs. Therefore, it is essential to have high acc

Physicians often utilize different imaging techniques to provide clear, visual information about internal parts of the patient. Since the different imaging modalities give different types of information, the combination of them serves as a powerful t
