We have already established a combined magnetic resonance (MRI) / ultra-wideband radar (UWB) prototype demonstrating the absence of any mutual interference between both systems, proving the feasibility of the UWB radar method to monitor respiratory and myocardial displacements in a 3 T scanner. In a further study we have shown the feasibility of UWB radar to detect involuntary head motions in the...
For the detection of tumours the application of a contrast agent to visualize the vascularization dynamic is common praxis in numerous imaging modalities, e.g. MRI or biomedical optics. Due to the high vascularization of several types of tumours, its contrast agent concentration exceeds the concentration in neighbouring tissue. Thus, the dielectric properties of the contrast agent will influence the...
To create a sufficient repository of test data for our model-based implementations of music information retrieval functions working on symbolic documents, we have used three different approaches to melodic segmentation on monophonic pieces with a broad range of genres from baroque/classical music to pop/rock. All three methods are driven by musical knowledge (in contrast to methods such as n-gram...
To date, there are no systems that can identify music, neither audio nor midi, in a generic way. That is, for the countless possible occurrences of a certain song, it should be possible to associate them with only one generic description of that song. In this paper we describe a conceptual design for generic music identification. Therefore, we propose a hierarchy of elementary music descriptions and...
Due to the recent advances in ultra-wideband (UWB)-radar technologies, there has been widespread interest in medical applications of this technology. We propose the multimodal combination of magnetic resonance (MR) and UWB-radar for improved functional diagnosis and imaging. A demonstrator was established to prove the feasibility of simultaneous acquisition of physiological events by magnetic resonance...
