摘要： Exciting light is projected onto a specimen such as an organic body, and an intensity in at least one wavelength range of fluorescence emitted from the specimen upon excitation by the exciting light is detected. Image data representing a fluorescence image of the specimen is obtained through an operation based on the intensity of the fluorescence. Whether each of pixels forming the fluorescence image is adequate for said operation is determined on the basis of the intensity of the fluorescence of each pixel. The operation is carried out on adequate pixels, which have been determined to be adequate for the operation, to obtain values for the adequate pixels while values which will not visually adversely affect the part of the fluorescence image corresponding to the adequate pixels are allotted to inadequate pixels, which have been determined not to be adequate for said operation.

摘要： A correction function is calculated based on a reference image formed of reflected light reflected upon the irradiation of a predetermined living tissue, for which a diseased state is known, with a reference light. This correction function is employed to administer distance correction on calculated standardized values based on fluorescence images to which an offset has been added, to correct the fluctuations of the calculated standardized values caused by the distance between living tissue and the distal end of a fluorescence endoscope, thereby generating a corrected standardized fluorescence image.

摘要： According to a fluorescent endoscope apparatus for detecting an autofluorescent-light image emitted from a living body upon irradiation thereof by stimulating light, when the endoscope insertion portion is inserted into or removed from a patients body, stimulating light is prevented from entering the eyes of the patient or the operator, ensuring for their safety. When the endoscope insertion portion is outside the body of a patient, the flicker occurring due to the fluorescent or other light illuminating the diagnosis room, which would be detected together with the autofluorescent-light image by a fluorescent-image use camera or with the normal image by a normal-image use camera, is detected by a flicker detector. The flicker detector outputs a detection signal to the stimulating light emission prevention controller, which turns off the power source to the stimulating light laser source by use of a controller computer and thereby prevents the emission of stimulating light.

摘要： Times at which requests for a data read or data write from/to a logical volume are received are stored in memory as access times of a RAID group making up the logical volume. When a predetermined time has elapsed after the access time, a number of the hard disk drives according to the redundancy of the RAID group are set to a power saving mode. Assume there are first hard disk drives and second hard disk drives having shorter lifes and the RAID group exceeds a predetermined time after the access time. When the RAID group consists of only the first drives, a number of the first drives according to the redundancy of the RAID group are set to a power saving mode and when it consists of only the second drives, an arbitrary number of second drives are set to a power saving mode.

摘要： A radiation image capturing apparatus includes a conductive gel member disposed between a radiation detector and an integrated circuit provided in vicinity of the radiation detector and electrically connected thereto. The conductive gel member blocks the electromagnetic noise generated by the integrated circuit and thereby prevents the electromagnetic noise from propagating to the radiation detector. As a result, the electrical signals generated by the radiation detector are prevented from being affected by the electromagnetic noise and high-quality radiation images can be acquired.

摘要： A solid-state radiation detector with increased pixel density. The solid-state radiation detector includes multitudes of linear signal wires for detecting recorded image information as image signals, and a signal detection means disposed on an opposing side of the detector substantially orthogonal to the linear signal wires, and connected to the linear signal wires to detect the image signals from the linear signal wires. A connection section of each of the linear signal wires, extending substantially orthogonal to the opposing side, for connection to the signal detection means is disposed such that the distance from the opposing side to each of the connection sections differs with each other.

摘要： A radiation image capturing apparatus includes a cooling mechanism for causing cooling medium to flow from a rear surface side to a radiation detector to a front surface side of radiation detector through a narrow space formed between an end of the radiation detector and a casing for housing the radiation detector. It is therefore possible to cool the narrow space, as well as regions in the vicinity of the narrow space, with the cooling medium and to discharge the cooling medium from the front surface side of the radiation detector.
