best direct conversion detectors

Direct-reading instruments or monitors (also called real-time instruments or monitors) provide information at the time of sampling, thus enabling rapid decision-making. these instruments can often provide the trained and experienced user the capability to determine if site personnel are exposed to airborne concentrations which exceed ...
Flat panel detectors (fpd) are used in direct digital radiography (ddr) for the conversion of x-rays to light (indirect conversion) or charge (direct conversion) which is read out using a thin film transistor (tft) array.. types. indirect conversion fpds. outermost layer is scintillator: phosphor screen (cesium iodide or gadolinium oxysulfide) detector: based on amorphous silicon photodiode

May 09, 2011 · in direct conversion fpxis, an x-ray photoconductor is used as the principal detecting element to convert the absorbed x-ray photons directly to collectable charge carries, which represent the signal.
