Real time magnetic resonance (MR) thermometry is gaining clinical importance for monitoring and guiding high intensity focused ultrasound (HIFU) ablations of tumorous tissue. The temperature information can be employed to adjust the position and the power of the HIFU system in real time and to determine the therapy end-point. However, the precision of real time MR-thermometry is generally limited...
In this paper, we present a study that deals with response time of Networked Automation Systems (NAS). The main aim is to verify experimentally the validity of an analytic formulation of NAS response time, obtained in our past investigations [12]. To that purpose, we carried out, under different conditions, a lot of measurements on a laboratory facility. Each time, we compared the observed measures...
Reliable range-based tracking using ultra-wideband (UWB) radio signals is traditionally problematic in indoor environments. It is indeed widely admitted that non line-of-sight (NLOS) channel configurations introduce significant biases on measured temporal metrics such as times of arrival (TOA), and hence, alter position estimates accordingly. In order to enhance the tracking performance, we propose...
