Title:
【発明の名称】時定数調整型誘電性レイヤを有する直接放射線透過用イメージパネル
Document Type and Number:
Japanese Patent JP2002520576
Kind Code:
A
Abstract:
A panel for radiation detection having a plurality of sensors arrayed thereon. Each sensor includes a charge storage capacitor, a radiation sensitive layer over the charge storage capacitor and a dielectric layer over the radiation sensitive layer. The dielectric layer has an adjusted resistivity resulting in a time constant τ=rhokappaepsi0 between 0.050 and 20 seconds, wherein kappa is the dielectric constant of the dielectric layer, and epsi0 is the permitivity of free space. The radiation detection layer is a photoconductor, and the dielectric layer is, preferably, a linear segmented polyurethane.
