چکیده
Real-time radiography systems employing an image intensifier tube have poor resolution (2 to 4Ip/mm) compared to their film-based counterparts (10 to 20 lp/mm). Phosphor bloom, especially in the output conversion phosphor [1], is the principle cause of reduced resolution. Other systems achieve higher resolution but at the expense of additional hardware complexity [2] or use of expensive materials [3]. We are investigating software-based image restoration techniques that can cost-effectively re cover resolution from existing image intensifier tube-based systems.

متن کاملCompputerized Station for Semi-automated Testing Image Intensifier Tubes
Testing of image intensifier tubes is still done using mostly manual methods due to a series of both technical and legal problems with test automation. Computerized stations for semi-automated testing of IITs are considered as novelty and are under continuous improvements. This paper presents a novel test station that enables semiautomated measurement of image intensifier tubes. Wide test capab...

متن کاملOptimum decoder for multiplicative spread spectrum image watermarking with Laplacian modeling
This paper investigates the multiplicative spread spectrum watermarking method for the image. The information bit is spreaded into middle-frequency Discrete Cosine Transform (DCT) coefficients of each block of an image using a generated pseudo-random sequence. Unlike the conventional signal modeling, we suppose that both signal and noise are distributed with Laplacian distribution, because the ...
متن کاملThe new ProfileView Software for Beam Induced Fluorescence Monitors
GSI accelerators are currently equipped with four Beam Induced Fluorescence (BIF) monitors. They determine the transverse beam profiles without beam disturbance by detecting the fluorescence light generated by excitation of a working gas (N2) with the passing ion beam. Therefore, they are well suited to observe the beam at multiple positions simultaneously [1]. The fluorescence photons are dete...
