Thoroughly designed, open-source toolkits emerge to boost progress in medical imaging. The Insight Toolkit (ITK) provides this for the algorithmic scope of medical imaging, especially for segmentation and registration. But medical imaging algorithms have to be clinically applied to be useful, which additionally requires visualization and interaction. The(More)
For determination of in vivo drug effects on nerve terminal GABA, a procedure was used which allowed the simultaneous measurement of GABA in nerve endings (synaptosomes) from 11 regions of one rat brain. Synaptosomal fractions were prepared by conventional subcellular fractionation procedures and characterized by electron microscopy. Postmortem increases of(More)
The aim of the Medical Imaging Interaction Toolkit (MITK) is to facilitate the creation of clinically usable image-based software. Clinically usable software for image-guided procedures and image analysis require a high degree of interaction to verify and, if necessary, correct results from (semi-)automatic algorithms. MITK is a class library basing on and(More)
Clear cell renal cell carcinoma (ccRCC) is the most common pathological subtype of kidney cancer. Here, we integrated an unbiased genome-wide RNA interference screen for ccRCC survival regulators with an analysis of recurrently overexpressed genes in ccRCC to identify new therapeutic targets in this disease. One of the most potent survival regulators, the(More)
Renal cell carcinoma (RCC) is a constellation of malignancies of different histological subtypes arising from the renal parenchyma. The clear cell histological subtype (ccRCC) accounts for around 75% of RCCs and is characterized by distinct genetic abnormalities, of which the loss of function of the von Hippel-Lindau (VHL) tumor suppressor gene is the most(More)
OBJECTIVE Software-based devices have increasingly become an important part of several clinical scenarios. Due to their critical impact on human life, medical devices have very strict safety requirements. It is therefore necessary to apply verification methods to ensure that the safety requirements are met. Verification of software-based devices is commonly(More)
The endoluminal brachytherapy of peripherally located bronchial carcinoma is difficult because of the complexity to position an irradiation catheter led by a bronchoscope to a desired spot inside a human lung. Furthermore the size of the bronchoscope permits only rarely the insertion of a catheter into the fine segment bronchi. We are developing an(More)
This paper describes a concept of an innovative medical application with augmented-reality support. This work is based on a cooperation between the Div. Medical and Biological Informatics at Deutsches Krebsforschungszentrum (DKFZ), and the Augmented Reality (AR) is a growing area in virtual reality research. An augmented reality system generates a composite(More)
