Research ArticleOpen accessEvery word in the titleContribution of the Entropy Function to the Study of Collimator for Nuclear Medicine ImagingM.S. Bouhdima, I. Elloumi, M.H.B. GhozlenScintigraphic image currently used in the diagnosis or the evaluation process of tissues, is strongly dependant on several technical parameters specially collimator characteristics. The present work describes a numerical method, based on entropy function, able to specify depth and hole diameter of collimator as well as other geometrical parameters to get a better accuracy in scintigraphy evaluation. From the classical … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,737 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Plastic Wedges on Whole Foot Radiograph in Anteroposterior and Oblique PositionsPoe Lorlorm, Winit Choiprasert, Montree Tungjai, Suchart KothanThe whole foot radiography may be taken twice with different exposure parameters. It produces two images in two radiation exposures; one is the metatarsal view of the phalange and the other is a tarsal view. The aim of this study was to study the effects of plastic wedges on whole foot radiography with one radiation exposure. The plastic wedge was … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 27 Apr 2017 · 7,591 accessesView PDF Cite
