  • Patent number: 9562992
    Abstract: Sensitivity is increased by enhancing the fluorescence collection efficiency while suppressing the increase in size of an objective lens. An objective lens 17 is structured to have a convex lens part 26 in a center portion and to have a truncated conical cylindrical body 27 around the convex lens part 26. Therefore, a fluorescence component b having too wide an emission angle to fit in the convex lens part 26, of fluorescence emitted from a sample 16, can be collected by total reflection on an outer peripheral surface 27b of the cylindrical body 27. Thus, even light having too wide an emission angle to be collected by a normal convex lens can be collected. As a result, it is possible to suppress the increase in size of the objective lens, to enhance the fluorescence collection efficiency, and to prevent the S/N ratio from being decreased by the existence of undetected fluorescence that is blocked by a prism 20. This can realize a fluorescence information reading device having high sensitivity.

  • Patent number: 7544962
    Abstract: In a method for reading out information stored in a phosphor layer whereby the phosphor layer is stimulated into emitting emission light by stimulation light produced from a light source, the emission light emitted from one or several areas of the phosphor layer is collected by a detector moved relative to the phosphor layer, and then converted into corresponding emission light signals. In order to improve the signal/noise ratio, the light source is momentarily switched off at least once during the movement of the detector relative to the phosphor layer. When the light source is switched off, a background, which is caused by the ambient light and/or dark currents in the detector, is collected by the detector and converted into a corresponding background signal. The background signal is then used for correcting the emission light signals.

    Abstract: A method for routine monitoring and quality assurance of field asymmetry of high energy circular radiation beam producing equipment. The quality assurance process of field symmetry for devices such as stereotactic radiosurgery (SRS) systems is simplified by directly measuring the integration of the half-beam profile. The method of the invention provides that the field symmetry is obtained by positioning the tip of an ion chamber, with a collecting length approximately half the diameter of the beam, at the central axis of the beam, and rotating the ion chamber at varying angular positions, acquiring and comparing readings at desired angular positions. Each pair of readings from positions 180 degrees opposed from each other, are plugged into the equation, Asymmetry=2(R1?R2)/(R1+R2) to compute asymmetry.

  • Patent number: 7433448
    Abstract: In a method for correcting pixels of an x-ray image data set, an x-ray exposure of a subject is acquired with an x-ray device that uses a storage film having a luminescent storage material layer serving as a radiation detector. The sensitivity of the luminescent storage material layer changes dependent on the accumulated x-ray radiation dose to which the storage layer has been exposed. After acquiring the x-ray exposure, the storage film is readout with a readout device and an x-ray image data set is generated that corresponds on a pixel-by-pixel basis with the x-ray exposure. Each pixel of the x-ray image data set is corrected with a correction value allocated to the corresponding pixel in the x-ray exposure, the correction value being adapted to the accumulated x-ray radiation dose to which the region of the storage film, containing the corresponding pixel, was exposed prior to acquiring the x-ray exposure.

  • Publication number: 20080142745
    Abstract: A radiation image formation read out method for a storage phosphor screen. A phosphor screen is exposed to a first stimulating radiation from a first side of the screen to release a first stimulated radiation in the pattern of the stored image. The first stimulating radiation is at a first power level, a first scan speed, and a first set of scanning parameters and is photoelectrically detected. The storage phosphor screen is again exposed to a second stimulating radiation from the first side of the screen to release a second stimulated radiation in the pattern of the stored image. The second stimulating radiation is at a second power level, a second scan speed, and a second set of scanning parameters. The second scanning exposure is higher than the first scanning exposure and the second set of scanning parameters differs in at least one parameter from the first set of scanning parameters.

  • Publication number: 20080078964
    Abstract: A radiation conversion panel allows recorded radiation image information to be read therefrom with high accuracy while reliably avoiding adverse effects of residual past radiation image information that remains in the radiation conversion panel. When a radiation conversion panel storing radiation image information therein is scanned by reading light from a reading light source, the radiation image information is read from first linear electrode layers, and scanned position information is read from a first linear electrode layer of a marker. A corrector corrects presently read radiation image information based on past radiation image information and scanned position information to acquire radiation image information free from the effect of a residue of the past radiation image information.

  • Patent number: 7335905
    Abstract: Corrective image data obtained by reading a stimulable phosphor sheet which is uniformly irradiated with a radiation are masked, and added and averaged into reference data. The ratio between the reference data and the corrective image data is generated as sensitivity correcting data. Desired radiation image information is then read from the stimulable phosphor sheet, corrected by the sensitivity correcting data, and outputted to an external image processing apparatus.
