Investigation of Dose Minimisation Protocol for 18F-FDG PET-CT in the Management of Lymphoma Postchemotherapy Followup

INTRODUCTION (18)F-FDG-PET-CT plays an important role in the management of lymphoma postchemotherapy followup. Some centres perform prechemotherapy baseline CT and postchemotherapy PETCT. With a concern of radiation burden, especially in young patients, this study aimed to assess if PETCT radiation dose could be reduced. METHODS Retrospective analysis of 100 lymphoma patients was performed to...

Scintillations of Ku Band Satellite Signal Related to Rain Attenuation at a Tropical Location

Scintillations of a Ku-band satellite signal are observed in association with rain attenuation at Kolkata, India. The wavelet analysis of signal fluctuations, due to simultaneous occurrence of scintillations and attenuation, reveals the relative impact of different scales of refractivity structures on the signal at different instants of time. A positive relationship exists between the peaks in ...

Influence of Phase Diffuser Dynamics on Scintillations of Laser Radiation in Earth Atmosphere: Long-Distance Propagation

The effect of a random phase diffuser on fluctuations of laser light (scintillations) is studied. Not only spatial but also temporal phase variations introduced by the phase diffuser are analyzed. The explicit dependence of the scintillation index on finite-time phase variations is obtained for long propagation paths. It is shown that for large amplitudes of phase fluctuations, a finite-time ef...
