Due to demographic reasons the percentage of elderly citizens in developed countries is rapidly increasing and as a consequence prevention of age-related problems is getting more important. Falls are amongst the most frequent causes for injuries to the aging population and many efforts have been concentrated in fall detection and prevention. This paper presents the design, implementation and experimental analysis of a portable wireless fall detector.

In fluoroscopy quantum noise is dominant with respect to other common noise sources, whose effects can be often neglected. Quantum noise is originated by the limited number of photons (low-dose X-ray) involved in fluoroscopic image formation; this noise is commonly modeled as Poisson distributed. Estimation of noise-parameters is required for evaluation of X-ray digital imaging sensors and in several image processing applications (e.g. denoising). The first aim of this work is to validate the analytically derived noise-parameter models by real fluoroscopic image sequences, also considering non-linear gray level mappings currently employed by fluoroscopic devices. A plain procedure for estimation of noise pixel-intensity variance as a function of mean pixel-intensity, which does not require specific test-objects but only some images screening a still scene, has been provided. Besides, a procedure for noise-parameter estimation by differencing fluoroscopic static images has been proposed. It computes image-pair differences, estimates concise parameters of the resulting Skellam distribution and, then, quotes Poisson noise-parameters. Image sequences of a simple step-phantom, acquired with a conventional fluoroscopic device, were utilized for performing the noise measurements. Experimental results confirmed a great agreement of the measured noise-parameters with those analytically derived and the possibility to use static images to estimate noise.

This paper provides an overview of results on the capacity of noncoherent, multiple-input multiple-output (MIMO) flat-fading channels with a bandlimited power spectral density. The focus is on results that concern the capacity at high signal-to-noise ratio (SNR). In particular, the capacity pre-log, defined as the limiting ratio of the capacity to the logarithm of the SNR as the SNR tends to infinity, is studied. It is observed that the capacity pre-log is a function of the number of antennas as well as of the bandwidth of the fading channel's power spectral density. It is further observed that the capacity pre-log can be achieved with a simple communication system where the data detection and the channel estimation are performed separately.

Magnetic particle imaging (MPI) is a new tomographic imaging approach that detects and localizes magnetic nano-particles by their non-linear magnetization response to externally applied fields. MPI allows quantitative, sensitive, and rapid volumetric imaging of distributions of particles injected into the blood stream. Initial experiments showing 3D real-time in-vivo imaging of mice were conducted using small imaging volumes covering a single organ. In view of scaling up the hardware for future clinical imaging, the imaging volume has to be increased. This contribution describes the basics of particle detection and spatial encoding in MPI, limitations to the imaging volume, and one approach to circumvent these limitations. Experimental results with increased volume coverage are presented.

This paper presents a smart kitchen system for supporting demented elderly cooking in a kitchen. In this system, a remote supporter provides a user with verbal and visual prompts manually. As a prompting method for this system projection should be chosen as a priority because it enables direct pointing of targets in a real scene. Even if projection is used as a priority, this system should be designed to solve three practical problems: 1) there are many areas where sharp images cannot be projected in a kitchen, 2) kitchen is a too complex environment to display visual prompts using only a single method, 3) remote supporters do not know the kitchen environment well enough. In this paper we propose a novel system overcoming the above problems as follows, respectively.1) The system first tries indirect projection of circular markers as visual prompts around target objects.2) Proper method is automatically selected from using projector, embedded monitor and illumination devices based on environmental information.3) The system automatically acquires flat surfaces to project on and their reflectance properties as the environmental information. Based on an observation of two elderly suffering from dementia, we discuss the feasibility and concrete problems in displaying visual prompt and how to solve them technically.

In this paper we present receiver design considerations and performance analysis for the physical layer of low data-rate non-coherent Ultra--Wideband Impulse Radio (UWB--IR) communication systems. Such UWB--IR systems are of particular interest in wireless medical Body Area Networks (BAN); in medical BAN the amount of traffic is relatively low, however, reliability of communication under body-shadowing and interference conditions is of utmost importance. Two non-coherent modulation/detection schemes are treated analytically and numerically through noise and interference performance studies. Particular attention is given to the performance enhancement achieved by compression of the received signal by methods previously introduced by the authors.

This paper describes a modified and enhanced version of the GPL-licensed, ITK-/VTK-based segmentation software ITK-SNAP. The modified software is entitled IMPPACT-SNAP and was motivated by the requirement for preoperative inspection and manual refinement of surface mesh liver segmentations in the research project IMPPACT. In this context, the liver segmentations are used for simulating the radiofrequency ablation of liver tumors to optimize the outcome of the treatment. The implemented modifications add the functionality of visualizing and manually deforming surface mesh segmentations and improve the navigational features of the software. The result is an easy-to-use tool that builds on ITK-SNAP's user-oriented GUI and framework.

ICT technologies are going to play more and more a fundamental role in the healthcare scenario. They aim to implement innovative e-health services able to improve patient safety and quality of care. Particular attention is focused on patients affected by multiple intolerances. This people struggle every day to perform elementary actions such as the choice of food and/or drugs because of the adverse reactions that particular components could cause if taken. New item-level tracing systems based on RFID and EPCglobal are very important and able to face these problems but they do not represent yet a complete solution. In fact, a very interesting challenge in the e-healthcare field is currently focused on the combining of tracing systems with hospital information systems, compliant to HL7 (Health Level Seven). In this paper, a prototypal ICT system able to support medical and nutritional applications, based on the combining of the two different standards EPCglobal and HL7, is shown exploiting a concrete case study in the immunology field. Potential benefits, derived from new e-health services for the main actors (e.g. doctors, pharmacists, patients, etc.), are discussed in order to define attractive future research works.
