摘要： A two dimensional collimator assembly and method of manufacturing thereof is disclosed. The collimator assembly includes a wall structure constructed to form a two dimensional array of channels to collimate x-rays. The wall structure further includes a first portion positioned proximate the object to be scanned and configured to absorb scattered x-rays and a second portion formed integrally with the first portion and extending out from the first portion away from the object to be scanned. The first portion of the wall structure has a height greater than a height of the second portion of the wall structure. The second portion of the wall structure includes a reflective material coated thereon in each of the channels forming the two dimensional array of channels.

摘要： Scintillator materials based on certain types of halide-lanthanide matrix materials are described. In one embodiment, the matrix material contains a mixture of lanthanide halides, i.e., a solid solution of at least two of the halides, such as lanthanum chloride and lanthanum bromide. In another embodiment, the matrix material is based on lanthanum iodide alone, which must be substantially free of lanthanum oxyiodide. The scintillator materials, which can be in monocrystalline or polycrystalline form, also include an activator for the matrix material, e.g., cerium. To further improve the stopping power and the scintillating efficiency of these halide scintillators, the addition of bismuth is disclosed. Radiation detectors that use the scintillators are also described, as are related methods for detecting high-energy radiation.
