摘要： A transparent scintillator panel including an extruded scintillation layer comprising a thermoplastic polyolefin and a scintillator material, wherein the transparent scintillator panel has an intrinsic MTF at least 5% greater than the iH50 of a solvent-coated DRZ+ screen. Also disclosed is a scintillation detection system including a transparent scintillator panel comprising an extruded scintillation layer comprising a thermoplastic olefin and a scintillator material; and at least one photodetector coupled to the transparent scintillator panel, wherein at least one photodetector is configured to detect photons generated from the transparent scintillator panel. Further disclosed is a method of making a transparent scintillator panel including providing thermoplastic particles comprising at least one thermoplastic polyolefin and a scintillator material; and melt extruding the thermoplastic particles to form an extruded scintillation layer.

摘要： A method and system for determining the bone mineral density of a body extremity. An image of a body extremity is acquired using a mammography x-ray system whereby a bone mineral density can be performed on the image. The system for determining the bone mineral density of a body extremity includes: a support for supporting the body extremity; a detector for capturing an image of the body extremity; and an x-ray source adapted to project an x-ray beam through the body extremity toward the detector, the x-ray source having a voltage of no more than about 45 kVp and having a target/filter combination of rhodium/rhodium, molybdenum/molybdenum, molybdenum/rhodium, or tungsten/rhodium. An attenuation filter separate from the target/filter combination may be provided between the source and the body extremity, between the body extremity and the detector, or both.
