Filter by:In case of surgical procedures in the head and neck region, MRI in combination with CT of the bone is often the standard modality to visualise bony landmarks for planning, navigation and risk assessment. An important downside of a CT scan is the associated radiation exposure, especially in children. An additional downside is the sedation or general anaesthesia needed for both the MRI and CT scan session in very young children. These downsides could be removed if the CT scan can be substituted by an MRI sequence that can provide the same information as CT. This project aims to determine the feasibility of recreating CT like images of the craniofacial bones from MRI images using machine learning techniques.
Assessment of the effectiveness of care in certified cancer centres for eight cancer entities via a retrospective cohort study based on secondary data from statutory health insurance funds and population-based clinical cancer registries.
The investigational part of this study is using a mobile PET/CT scanner to take images of the participants tumor immediately after they are treated with proton radiation. This allows the participant to be treated and imaged on the same bed. The information obtained may improve the accuracy of treatment and may help to minimize the dose delivered unnecessarily to healthy tissue.
This study will evaluate the feasibility of higher and prolonged dose escalation concentrated in the intra-tumoral regions which are FDG-avid after two weeks of radiotherapy.
