The academic community comprises 30.280 members; 28194 are students in the two principal degree courses, 680 are post graduate students, 1.325 are teaching staff and 734 form the administrative and services body, 14.161 are students in short duration stage and 14.033 are in long duration stage. This university offers degrees and postgraduate degrees in Telecommunications Engineering, Civil Engineering, Industrial Engineering, Architecture and Computing Engineering

 

The Bioengineering, Electronic and Telemedicine Group (BET)  is R&D group within the university, being devoted to the field of medical bioingeneering and telemedicine. BET has a large experience on several research and development projects in the e-health field with fundings from European Commision ( IST, TEN-TELECOM initiatives)  Spanish and regional government (FEDER, PISTACABLE, Science and Technology Ministry, IMPIVA, IVESP, SVS) and also private companies.

 

Main activities carried out dealing with the e-health field are:

BET researchers have  published in this field more than 20 technical papers in national and international journals, having participated in more than 100 seminars and congresses. Results of applications and services have been presented in international and national fairs ( ie. Telemedicine and Telecare International Trade Fair 2002 – Luxemburgo, Solucion.es TIC 2002-Valencia, FITEC – Barcelona,…)

 

The Bioengineering, Electronics and Telemedicina Group (BET) of the Universidad Politécnica de Valencia can mainly provide its expertise in the A1 and T4 JPAs of the PATIMON NoE.

 

JPA A1: Communication patient – physician

 

BET has a wide experience in applications which are oriented to the remote interaction between practitioner and patients and between health care professionals using communication networks. A number of products can me mentioned: Tele-home care platform over high bandwidth networks, Teleasisitance System for distributed campus wide environments, Personal Telemonitoring System device for biomedical signal capture, processing and transmission over wireless networks, ASP platform for teleconsultancy and telemonitoring over internet/intranet, and other peripherals and tools. Technology and generic services are videoconference over IP (H.323) and ISDN (H.320); Cable Modem, DSL and ISDN communication networks, GPRS and Bluetooth wireless communication, EJ2EE and MS .NET web-internet technology, Open Software in the health care domain. The BET division are currently being involved in knowledge management and data mining technology domains applied in the health care sector.

The users groups targeted by the BET are those involved in the care of chronic and acute ill people, disabled and elderly, including professionals, social carers, therapist, patients, relatives and professionals and informal assistants. BET is working actively on several research and development projects in the e-health field funded by the EU Research Programme ( BABEL, ATTRACT, TEN CARE, D-LAB, CONFIDENT, HEALTHMATE, HEALTHY MARKET, ACTIVE HEALTH & IDEAS in e-HEALTH).

  

JPA T4: signal processing, classification, recognition

 

BET can provide to PATIMON expertise on advanced biomedical signal processing, mainly based on the electrocardiogram. From the analysis of the electrocardiogram it can be automatically detected a large number of cardiovascular diseases, which is useful for monitoring patient at high risk outside hospitals. Our developed algorithms are really diverse, depending on the application itself, from the study and analysis of ventricular tachycardias, ventricular fibrillation to atrial arrhythmias as atrial flutter or atrial fibrillation. The techniques employed consist of multidimensional statistical signal processing, considering spatio-temporal models, independent component analysis, neural networks, which can provide or enhance some characteristics of raw data. Frequency and time-frequency analysis provide also very useful information.

From the outputs given by signal processing blocks, some parameters (which depende on the final application) are measured. The correct definition of relevant parameters is crucial for the success in solving the problem. With the values of the parameters, a final classification block will decide among the state of the patient, whether presents normal sinus rhythm, or has suffered a cardiac disease, or even the system can predict the risk of a cardiovascular disease so that the system and/or the doctors should remain alert. In order to improve sensibility/specificity ratios, classification algorithms based on the latest statistical advances as support vector machines, neural networks, etc. are employed.

It should be pointed out that the algorithms can work either on a 12-lead standard ECG or on a signal recorded in a Holter device.

 

BET Group has also experience in the development of clinical decision support systems, using an inductive approximation to learn the characteristics of the problem and adapt the system to resolve it.

 

Using biomedical signal processing in addition to pattern recognition systems an intelligent patient monitoring can be install in a particular situation and environment

 

We propose a two-level monitoring system:

 

-         The environment level: which is useful to integrated the home sensor system to control the correct situation in the home of the patient. This system is developed as a simple virtual machine with a easy programming language that allow the installer to adapt the system to the situation at the patient home.

-         The biomedical signal pattern recognition: which is useful to control the correct situation of the patient, monitoring its vital signals to prevent any crisis episode. This level is adapted by the use of machine learning procedures like statistic methods, neural networks, hidden Markov models, etc. and is based in the prevention of rich situations by the identification of the pattern that causes it.

 

BET Group is currently developing CDSS to characterize soft tissue tumours beging/malignant and histologists characterization by the use of a magnetic resonance imaging protocol. The group is working in health and nutrional prevention system and other diseases characterization.
