Radiation sensing thermoplastic composite panels

An inorganic storage phosphor detection system comprising:

• an extruded inorganic storage phosphor panel comprising an extruded inorganic storage phosphor layer comprising a thermoplastic polyolefin and an inorganic storage phosphor material, where the extruded inorganic storage phosphor layer does not include a support and requires irradiation with a longer wavelength radiation, subsequent to x-ray exposure, for stimulated emission of light for detection, where the extruded inorganic storage phosphor panel has a detection quantum efficiency (DQE) that is within 10% of a solvent coated inorganic storage phosphor screen having similar x-ray absorbance at a spatial frequency of 6 line lp/mm or 8 lp/mm, where the storage phosphor used in the extruded inorganic storage phosphor panel and the solvent coated inorganic storage phosphor screen are the same;
• and
• at least one photodetector coupled to the extruded inorganic storage phosphor panel, wherein at least one photodetector is configured to detect photons generated from the extruded inorganic storage phosphor panel.

A method of making an extruded inorganic storage phosphor panel comprising:

• providing thermoplastic particles comprising at least one thermoplastic polyolefin and an inorganic storage phosphor material, where the inorganic storage phosphor material requires irradiation with a longer wavelength radiation, subsequent to x-ray exposure, for stimulated emission of light for detection;
• and
• melt extruding the thermoplastic particles to form an extruded inorganic storage phosphor layer, where the extruded inorganic storage phosphor panel has a detection quantum efficiency (DQE) that is within 10% of a solvent coated inorganic storage phosphor screen having similar x-ray absorbance at a spatial frequency of 6 line lp/mm or 8 lp/mm, where the storage phosphor used in the extruded inorganic storage phosphor panel and the solvent coated inorganic storage phosphor screen are the same.
