چکیده
Abstract A standalone, lightweight, portable, FPGA-based triple to double coincidence ratio (TDCR) system is developed. The optical chamber of the fabricated in a dual, coaxial cylindrical geometry, with inner cylinder made up Teflon and outer one aluminium. Three square PMTs, each having an active cathode area 2.3 cm × cm, are housed chamber. variation detection efficiency identify optimum kB (ionization quenching parameter) value achieved by changing vial position vertically respect centre line PMTs. analyzer implemented field programmable gate array (FPGA) transfers pulse counts associated parameters real time Raspberry Pi single board computer (SBC). TDCR algorithm compute SBC. In addition, SBC interfaced local 7” touchscreen provide intuitive graphical user interface (GUI) for operating standalone instrument. performance validated 3 H 14 C radionuclide standards.

متن کاملFPGA-Based Portable Ultrasound Scanning System with Automatic Kidney Detection
Bedsides diagnosis using portable ultrasound scanning (PUS) offering comfortable diagnosis with various clinical advantages, in general, ultrasound scanners suffer from a poor signal-to-noise ratio, and physicians who operate the device at point-of-care may not be adequately trained to perform high level diagnosis. Such scenarios can be eradicated by incorporating ambient intelligence in PUS. I...

متن کاملDevelopment System for FPGA-Based Digital Circuits
The paper discusses some new hardware and software tools that can be used for the design of virtual circuits based on dynamically reconfigurable FPGAs. With the aid of these tools we can implement a system that requires some hardware resources Rc, on available hardware that has resources Rh, where Rc>Rh. The main idea of the approach supported by these tools is the rational combination of FPGA ...
