This study presents a design of a high-speed photon counting readout circuit for spectral computed tomography detectors. We propose a novel front-end architecture aimed to reduce a dead time by introducing dual signal paths in each pixel. A prototype chip is fabricated with 0.18um six-metal standard CMOS process that consists of 16 × 16 pixels and periphery circuits. Each pixel has 200um pixel pitch...
As various e-Health providers gain access to new sources of electronic health data while more entities are collecting evidence of effective healthcare procedures, we research the privacy/security/trust services mechanisms in the expanding electronic healthcare and administration environment to enable mobile e-Health applications deployment. To address the significant trends in e-Health PST rules after...
As the world is gearing up towards implementation of digital healthcare networking solutions, the solution roadmap for a national e-Health interconnection network infrastructure is in great demand. This paper first identifies the major benefits in interconnection services that are critical to universal deployment. Then it provides an overview of our e-Health AON (Application Oriented Network) approach...
From the pervasive application standpoint, healthcare IT (HIT) infrastructure and applications have become enablers to revolutionize the roles and responsibility of the healthcare professionals as well as consumers. This paper describes our research in next generation service creation systems that support pervasive healthcare applications together with additional operational management capabilities...
