OBJECTIVE To assess the use of real-time elastography (RTE) for detecting prostate cancer in patients scheduled for radical prostatectomy (RP), as most solid tumours differ in their consistency from the deriving tissue, and RTE might offer a new tool for cancer detection. PATIENTS AND METHODS We examined 15 patients (mean age 56 years, sd 6.2, range(More)
PURPOSE Based on our first experiences with real-time elastography in the field of prostate diagnostics we evaluate its usefulness for biopsy guidance for prostate cancer detection. MATERIALS AND METHODS After imaging with conventional B-mode ultrasound in conjunction with real-time elastography 404 men underwent systematic sextant biopsy. RESULTS(More)
The key for successfully deploy mobile applications is the ability to understand the specific needs of its customers. In the field of mobile health monitoring, the currently most important user group is the group of persons of the age 50+. In our project senSAVE® we developed a user interface for monitoring personal vital parameters that is(More)
Modern personalized information systems have been proven to support the user with information at the appropriate level and in the appropriate form. In specific environments like museums and exhibitions, focusing on the control of such a system is contradictory to establishing a relationship with the artifacts and exhibits. Preferably, the technology becomes(More)
Currently, much research aims at coping with the shortcomings in multimedia consumption that may exist in a user’s current context, e.g., due to the absence of appropriate devices at many locations, a lack of capabilities of mobile devices, restricted access to content, or nonpersonalized user interfaces. Recently, solutions to specific problems have been(More)
Medical health care is undergoing a significant change of paradigm. Moving health care from health centers to home environments poses new challenges for acquisition, management and mobile exchange of information. The HealthNet project at RWTH Aachen University has developed a prototype which addresses these new challenges: a Body Sensor Network (BSN)(More)
The Wnt/β-catenin signaling pathway plays crucial roles in early hindbrain formation, and its constitutive activity is associated with a subset of human medulloblastoma, a malignant childhood tumor of the posterior fossa. However, the precise function of Wnt/β-catenin signaling during cerebellar development is still elusive. We generated(More)
Supporting the individual user in his working, learning, or information access is one of the main goals of user modeling. Personal or group user models make it possible to represent and use information about preferences, knowledge, abilities, emotional states, and many other characteristics of a user to adapt the user experience and support. Nowadays, the(More)
