摘要： A method of preparing a barium fluorohalide phosphor including a mixing step in which phosphor materials are mixed, a firing step in which a resulting mixture of phosphor materials is fired, an annealing step, and a cooling step in which the mixture of phosphor materials is cooled to the ordinary temperature. In the firing step, after the mixture of phosphor materials has been fired at a constant temperature, an atmosphere at the time of the firing is removed while the constant temperature is maintained, and is replaced with an atmosphere different from the atmosphere at the time of the firing, and thereafter, annealing is carried out. In the cooling step, the atmosphere at the time of the firing is removed and replaced with a first different atmosphere, and then first cooling is carried out. Further, the first atmosphere is removed and replaced with a second atmosphere, and then second cooling is carried out. Alternatively, in the cooling step, the atmosphere at the time of the firing is removed and replaced with vacuum or a neutral gas atmosphere, and then cooling is carried out.

摘要： The present invention provides a method and apparatus for preparing a rare earth-activated barium fluorohalide based phosphor, in which atmospheric states during calcining and during cooling can be optimally adjusted and a cooling rate can be selected in a wide range. In the preparing apparatus of the present invention, a mixture 18 of phosphor materials is calcined by a calcining furnace 10 to form a calcined product, and thereafter, the calcined product is cooled to thereby prepare a rare earth-activated barium fluorohalide based phosphor. A calcining region 12 in which the mixture of phosphor materials can be calcined is provided in the calcining furnace 10, and a portion of the calcining region 12 is connected, via a partition door 30 capable of being opened and closed, to a cooling region 28 in which the calcined product can be cooled, at an outer side of the calcining furnace 10. Further, the method for preparing the rare earth activated barium fluorohalide based phosphor of the present invention is carried out by using the above-described preparing apparatus.

摘要： A method, apparatus and program for image processing capable of obtaining useful information for identifying the abnormal pulmonary ventilation region from the projected chest radiation images. An air-inhaled image obtained when air is inhaled into lungs and a gas-inhaled image obtained when non-radioactive xenon gas is inhaled into the lungs are aligned by the aligning means, and a subtraction image representing the difference between the two images aligned by the aligning means is created by the subtraction image creating means. The information representing the abnormal pulmonary ventilation region is indicated in the subtraction image in which the anatomical noise arising from the bony part and the like, and artifacts arising from the positional displacement due to the change in the bodily posture of the subject are suppressed.
