“…The receiver operating characteristic (ROC) curves are employed to evaluate the performance of the integrated synchronous data acquisition subsystem in this paper. ROC curve is a technique for summarising a data acquisition system's performance over a range by considering the tradeoffs between TP rate and FP rate [24][25] The ROC curve is created by comparing the probability of discovery (P_D) (the rate of true positives TP, see (1)) and probability of false alarm (P_FA) (the rate of false positives FP see (2)), at various threshold levels [26] P_D = TP/ TP + FN…”

“…Ground penetrating radar (GPR) has become a valuable tool for the non-destructive testing of the steel-reinforcing bars in highway or concrete bridge decks for the past 20 years, leading to the development of a variety of GPR systems for this application [1][2][3][4]. However, various factors of the most commercial GPR data acquisition system, such as the low rate equivalent time sampling (ETS) method, relatively low signal sampling rate [5][6][7][8][9][10], limit the scanning speed of these GPRs to speeds that are too slow to move with traffic, and instead require lane closures and other traffic disruptions [4,11,12].…”

In this study, an integrated synchronous data acquisition subsystem for high-speed dual-channel ultra-wideband ground penetrating radar (GPR) system is designed and tested. Factors that could cause data missing and asynchronisation are analyzed. According to timing sequence, a field-programmable gate array-based onboard digital control module is integrated to synchronise the data acquisition and data storage subsystems. By applying simultaneous multi-buffer acquisition and readout mode and multi-threading configuration, as well as the critical section control and queue storage structure, the GPR data throughput is considerably improved. For the practicality of this system, a smart End-of-Job control design is performed between different threads to control data acquisition. By using different performance indexes, receiver operation characteristic curve, maximum scan rate, and the rebar detection experiment demonstrate the superiority of author's method.

The Internet of medical things is an emerging information network technology, which can realize the automatic identification, monitoring and management of personnel, medical equipment, medicines, etc. through this network, and is an effective means to reduce medical errors and improve work efficiency. This article first studies the theory and method of health information and sports information collection, that is, the temperature sensor and the acceleration sensor are used to collect human body temperature and exercise steps, respectively, and then estimate the human health and sports. Second, the prototype system of health and sports information collection system is realized the system is divided into two parts: terminal node and client information management system. Finally, a component collaborative modeling and data analysis method for Internet of medical things is proposed. This method constructs different types of components according to different functions of the Internet of Things equipment, and designs a set of communication mechanisms between the components based on the Internet of Things network communication characteristics, and uses visual methods to model. The experimental results verify that the method of collecting and analyzing human motion information using a motion information collection system is feasible. Multiple methods should be integrated to obtain as much information as possible to make the human motion analysis more scientific and reasonable.INDEX TERMS Internet of medical things, motion information collection, collaborative modeling, data analysis, prototype.

“…With current commercial whole-body PET, spatial resolution is about the 3-6 mm [11,12]. The PMT-Quadrant-Sharing (PQS) detectors are commonly used to build a larger aperture PET camera [13][14][15]. It is necessary to cut several grooves (~200 µm) on the surface of the solid materials (optical glass or crystal) to guide the photons produced by gamma photon, which is difficult and expensive.…”

A γ -photon detector based on liquid light guide for whole-body PET

A: Positron Emission Tomography (PET) is important for accurate diagnosis of critical diseases. The quality of PET imaging highly depends on the performance of the detector module. In this study, we present a new method to design and assemble light-sharing block detectors which utilizes liquid instead of optical glass as a light guide. An integrated framework glued with Enhanced Specular Reflector (ESR) was built to hold the discrete crystals. A GATE-based simulation algorithm has been developed to optimize the heights of the reflectors for a good decoding accuracy. We fabricated a prototype block detector with a 12 × 12 array of LYSO scintillators and performed experiments to characterize the energy resolution and crystal decoding accuracy of the detector. The average energy resolution of the detector is 14.4% with a variance of 1.2%. The average peak-valley ratio of the profile is 3.95. The results show that it is possible to fabricate high performance PET detectors using the liquid light guide.
