Database and data structure for the novel TOF-PET detector developed for J-PET project

The complexity of the hardware and the amount of data collected during the PET imaging process require application of modern methods of efficient data organization and processing. In this article we will discuss the data structures and the flow of collected data from the novel TOF-PET medical scanner which is being developed at the Jagiellonian University. The developed data format reflects: registration process of the gamma quanta emitted from positron-electron annihilation, Front-End Electronic (FEE) structure and required input information for the image reconstruction. In addition, the system database fulfills possible demands of the evolving J-PET project.

Computing support for advanced medical data analysis and imaging

We discuss computing issues for data analysis and image reconstruction of PET-TOF medical scanner or other medical scanning devices producing large volumes of data. Service architecture based on the grid and cloud concepts for distributed processing is proposed and critically discussed.

Spectral and kinetic properties of electroluminescence of ZnS:Cu powder in polymer structure

Spectral and kinetic measurements of the light output have been made for AC electroluminescent structure. ZnS:Cu is luminescence active layer in the structure. In kinetic measurements, excitation was by rectangular wave voltage pulse of 1 ms duration. During the excitation the structure emits blue-green light. The maximum of the spectrum lies at about 455 nm.
