Quantitative Computed Tomography Abstract Computed Tomography (CT) is a wide-spread medical imaging modality. Traditional CT yields information on a patient’s anatomy in form of slice images or volume data. Hounsfield Units (HU) are used to quantify the imaged tissue properties. Due to the polychromatic nature of X-rays in CT, the HU values for a specific […]

Time-of-Flight – A New Modality for Radiotherapy Abstract In this work, one of the first approaches utilizing so-called Time-of-Flight cameras for medical applications is presented. Using Time-of-Flight cameras it is feasible to acquire a 3-D model in real-time with a single sensor. Several systems for managing motion within radiotherapy are presented. There are five major […]

Interventional Perfusion Imaging Using C-arm Computed Tomography: Algorithms and Clinical Evaluation Abstract A stroke is a medical emergency which requires immediate diagnosis and treatment. For several years, image-based stroke diagnosis has been assisted using perfusion computed tomography (CT) and perfusion magnetic resonance imaging (MRI). A contrast agent bolus is injected and time-resolved imaging, at typically […]Interventional Perfusion Imaging Using C-arm Computed Tomography: Algorithms and Clinical Evaluation Abstract A stroke is a medical emergency which requires immediate diagnosis and treatment.
