The resolution of a spark imaging camera with parallel channel collima-tors


, : The resolution of a spark imaging camera with parallel channel collima-tors. Phys Med Biol 11(3): 411-422

The results of resolution measurements performed on a spark imaging camera are presented. The minimum separation distance is shown to be essentially defined by the collimator design. Excellent images of a hexagonally-shaped phantom are obtained with the spark camera and these are compared with scintiscans of the same phantom. The spark camera exhibits a resolution superior to that obtainable with scintillation line scanners. Early work in which the spark camera was applied to radiography with microcurle sources is described.

Sardinia is a major centre of diversity of Anchusa, but the systematics, phylogenetic relationships and conservation status of the taxa endemic to the island are still poorly known mainly because of their remarkable rarity. We present a study on...

Amyotrophic lateral sclerosis (ALS) shows a strong genetic basis, with SOD1, FUS, TARDBP, and C9ORF72 being the genes most frequently involved. This has allowed identification of asymptomatic mutation carriers, which may be of help in understandin...
