In experimental nuclear physics, HPGe segmented detectors are used to provide high energy resolution of the gamma rays. Besides, 4pi configuration is common to get a full coverage of the interaction point and detection of all the products of the collisions. In this type of experiments, the number of electronic channels can be high (>100) and also the sampling frequency of the digitizing system...
The electronics of AGATA HPGe segmented gamma ray detector faces a new challenge in the search of a bigger integration and cost reduction for the phase 2 of the experiment going beyond 45 crystals. This opportunity can be used to introduce a new architecture based on commercial standards while keeping backward compatibility with current electronics. In this sense, new FPGA devices and fast Ethernet...
Pressure ulcers (PU) category I are defined by intact skin with non-blanchable erythema of a localized area, usually over a bony prominence. Although they are often underdiagnosed, they may indicate “at risk” persons. There are available different procedures to diagnose pressure ulcers category I, such as but these methods can produce a misdiagnosis. Infrared thermal imaging may be helpful to resolve...
Evidence of risk of pressure ulcers in neonates pro is related to the type of bearing surface on which the neonate lays. To prevent pressure ulcers is necessary to know which of the available commercial surfaces is the most convenient. The goal of this work is to evaluate the interface and redistribution pressure of five constant low pressure devices (special surfaces for pressure management [SEMP]...
Compton Cameras have been proposed as an alternative to SPECT imaging with Gamma Camera, mainly due to factors such as the electronic collimation, which allows a bigger field of view and provides further information from the acquired events if compared to devices with mechanical collimation. By contrast, this involves a higher amount of data to be processed. In medical devices this leads to waiting...
This work presents a study of a high-resolution Plastic Scintillating Fiber (PSF) based hodoscope for beam positioning and beam calibration. The aim of this work is to provide useful information to carry out a sound comparison between the results obtained from the electronics read-out designed for the hodoscope versus the results obtained from Geant4 simulations of the PSF detector; therefore, to...
