We have studied a new and inexpensive method of measuring the depth interaction (DOI) in /spl gamma/-ray detectors with large-sized scintillation crystals. This takes advantage strong correlation between width undisturbed light-distribution continuous crystals gamma/-ray's DOI. In order to quantify dependence distribution's respect DOI, we first an analytical model tested it by means Monte Carlo (MC) simulations light transport inside crystal. Further present modification commonly used...
Design optimization, manufacturing, and tests, both laboratory clinical, of a portable gamma camera for medical applications are presented. This camera, based on continuous scintillation crystal position‐sensitive photomultiplier tube, has an intrinsic spatial resolution , energy 13% at 140 keV, linearities 0.28 mm (absolute) 0.15 (differential), with useful field view 4.6 cm diameter. Our can image small organs high efficiency so it address the demand devices specific clinical like thyroid...
We have developed two prototypes of portable gamma cameras for medical applications based on a previous prototype designed and tested by our group. These use continuous scintillation crystal coupled to the new flat‐panel‐type multianode position‐sensitive photomultiplier tube, H8500 from Hamamatsu Photonics. One prototypes, mainly intended intrasurgical use, has field view , weighs . Its intrinsic resolution is better than its energy about 13% at The second prototype, osteological, renal,...
The increase in life expectancy, and the consequent growth of elderly population, represents a major challenge to guarantee adequate health social care. proposed system aims provide tool that automates evaluation gait balance, essential prevent falls older people. Through an RGB-D camera, it is possible capture digitally represent certain parameters describe how users carry out human motions poses. Such individual poses are actually related items included many well-known balance tests....
This paper studies the use of Neural Networks (NNs) for estimating position impinging photons in gamma ray detector modules PET cameras based on continuous scintillators and Multi-Anode Photomultiplier Tubes (MA-PMTs). The under study is composed a 49/spl times/49/spl times/10 mm/sup 3/ slab LSO coupled to flat panel H8500 MA-PMT. Four digitized signals from charge division circuit, which collects currents 8/spl times/8 anode matrix photomultiplier, are used as inputs NN, thus reducing...
This paper describes Cybi, an inexpensive smart companion mobile robot for elderly and disabled people. The software architecture that enables users to perform telepresence teleoperation tasks with Cybi is based on combining Cloud Computing technologies Fuzzy Logic. On one hand, the can be remotely teleoperated from a thin client by executing specific module of distributed component uses ROS, WebRTC Google App Engine. other capable understanding simple spoken orders allow it navigate through...
Crop sustainability is essential for balancing economic development and environmental care, mainly in strong very competitive regions the agri-food sector, such as Region of Murcia Spain, considered to be orchard Europe, despite being a semi-arid area with an important scarcity fresh water. In this region, farmers apply efficient techniques minimize supplies maximize quality productivity; however, effects climate change degradation significant natural environments, as, "Mar Menor", most...
This paper describes a system for remotely monitoring elderly people in the context of ambient assisted living that consists an inexpensive mobile robot, commercial computer, smart device running Android and Wireless Sensor Network (WSN). A
Background: After its introduction in the ICD-10-CM 2016, sarcopenia is a condition widely considered to be medical disease with important consequences for elderly. Considering high prevalence older adults and detrimental effects on health, it essential identify risk factors inform targeted interventions. Methods: Taking data from wave 2 of ELSA, using ML-based methods, this study investigates which are significantly associated sarcopenia. The Minimum Redundancy Maximum Relevance algorithm...
This paper is framed into the Positron Emission Mammography (PEM) project, whose aim to develop an innovative gamma ray sensor for early breast cancer diagnosis. Currently, detected using low-energy X-ray screening. However, functional imaging techniques such as PET/FDG could be employed detect and track disease changes with greater sensitivity. Furthermore, a small less expensive PET camera can utilized minimizing main problems of whole body PET. To accomplish these objectives, we are...
Current testbenches for nuclear imaging devices aim to simulate only a single stage of the system at time. This approach is useful in early design stages where accuracy not necessary. However, it would be desirable that different tools could combined achieve more detailed simulations. In this work, high precision testbench presented. It has been developed test systems. Its lies possibility linking simulation using right one each part system. High energy events are simulated Geant4 (High...
