摘要： Systems devices and methods in accordance with the invention impart high strength index of refraction patterns to photosensitive optical devices, such as Bragg gratings written in optical fibers. A length of small diameter fiber retaining photosensitivity is fabricated by flame elongation of an optical fiber precursor having dopant containing cladding, using a diffuse, low velocity inverted flame that does not introduce water, OH or H2 into the fiber. By varying the flame velocity during each scan the fiber is diminished to a small, uniform diameter, waist region. Photosensitivity is preserved and enhanced by exposure of the prepared waist region to scanning actinic illumination within an in-diffusing environment of pressurizing hydrogen or deuterium, and controlling the exposure to optimize the photo-induced index change.

摘要： With regard to a radiation therapy planning device, the radiation planning fluoroscopic image shown on the screen of an image display monitor 6 is a large field fluoroscopic image P in which an in-progress fluoroscopic image PA is joined with a previously acquired fluoroscopic image PB. In addition, a large field fluoroscopic image P is acquired using an X-ray detector which does not produce any image distortions. As a result, the field of view for radiation planning fluoroscopic image is expanded by the amount of the previously acquired fluoroscopic image PB that is combined with the in-progress fluoroscopic image PA. In addition, with boundary line PL which is overlaid on the radiation planning fluoroscopic image, the boundary between fluoroscopic images PA and PB can be identified at a glance. As a result, even if in-progress fluoroscopic image PA and previously acquired fluoroscopic image PB is displayed simultaneously and contiguous to each other on the screen of the image display monitor 6, previously acquired fluoroscopic image PB does not interfere in the observation of the radiation planning fluoroscopic image. As a result, the field of view of the radiation planning fluoroscopic image in enlarged appropriately.

摘要： In a method and apparatus for predicting process results of objects being processed in a processing chamber of a processing apparatus, operation data and process result data obtained at the time of processing each of the objects are collected and a multivariate analysis is performed on the basis of the collected operation data and process result data to obtain a first correlation therebetween. Process results are predicted on the basis of the first correlation. Weighting coefficients for the respective operation data are set on the basis of the predicted process results. A second correlation between the weighted operation data and the process result data is obtained by a multivariate analysis. Process results are predicted by using operation data, obtained when objects other than the objects used to obtain the second correlation are processed, on the basis of the second correlation.

摘要： An image pickup apparatus of a radiological imaging apparatus includes a plurality of radiation detectors arranged in a ring form around a through hole section formed on a casing into which an examinee is inserted. An X-ray source unit having an X-ray source moves in a circumferential direction of the through hole section along a ring-shaped guide rail provided on the casing. Each radiation detector outputs both an X-ray detection signal which is a detection signal of X-rays that have passed through the examinee and a null-ray detection signal which is a detection signal of null-rays radiated from the examinee caused by radiopharmaceutical. A computer creates an X-ray computed tomographic image data based on the X-ray detection signal and a PET image data based on the null-ray detection signal and creates fused tomographic image data using the X-ray computed tomographic image data and the PET image data.
