摘要： A tomosynthetic image taking apparatus takes an x-ray image of an object in each of a plurality of positions of an x-ray source to obtain a desired tomogram of the object by adding up the x-ray images thus obtained. A heartbeat phase is detected and the tomosynthetic image taking apparatus is controlled to take an x-ray image of the object in each of the plurality of positions of the x-ray source when the heartbeat of the object is in the same heartbeat phase.

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： A fluorescence image display apparatus is provided; wherein, when a pseudo color image representing the tissue state of a target subject is obtained, based on a fluorescence image emitted from the target subject upon the irradiation thereof by an excitation light, the tissue state can be recognized regardless of the intensity of the fluorescent light. Based upon the statistical quantity of a wide band fluorescence image computed by a statistical quantity computing means, a gain that the wide band and narrow band fluorescence image data are to be multiplied by is computed by a gain computing means. A gain multiplying means multiplies the wide band and narrow band fluorescence image data by the gain, whereby a green gradation is assigned to the wide band fluorescence image and a red gradation is assigned to the narrow band fluorescence image, and a composite image data is obtained by an image composing means.

摘要： An image obtaining method and apparatus for an endoscope apparatus wherein reductions to the gradations of the image data borne by the analog signal are suppressed and digital values having a narrower dynamic range are obtained when the photoelectrically converted and outputted analog signal is converted to digital values. A living tissue is irradiated by an illuminating light and an excitation light, which are each emitted at different timings; whereupon a fluorescent image formed of the fluorescent light emitted from the living tissue and a standard image formed of the reflected light reflected from the living tissue are received, converted to respective analog signals, and outputted by the same photoelectric converting element. In converting these analog signals to digital values, the analog signal representing the fluorescent image is amplified by a larger gain than that representing the standard image.

摘要： A method and apparatus for obtaining a dynamic radiographic image with enhanced resolution, in which an electrocardiogram of a subject is obtained, and five time phases are allocated to each cardiac beat period (1 second). The initial X-ray irradiation is performed at 1st time phase of 1st beat to obtain a radiographic image. Thereafter, X-ray irradiations are performed sequentially at 2nd time phase of 2nd beat, at 3rd time phase of 3rd beat, at 4th time phase of 4th beat, and at 5th time phase of 5th beat to obtain respective radiographic images. The five radiographic images obtained are combined at the time interval of 0.2 seconds to be displayed as a motion image. The time interval between the irradiations of the X-ray is 1.2 seconds, so that image signals corresponding to 1st to 5th time phases may be obtained with high resolution.

摘要： A radiation emission control method, apparatus and the program capable of detecting respiratory phases of a test subject with constant accuracy and emitting radiation rays to the test subject in synchronization with an intended respiratory phase, while minimizing the radiation exposure to the subject. A test subject having a contour that varies with the respiration is optically imaged continuously by the optical image obtaining section to sequentially obtain optical images of the subject, and respiratory phases of the subject are detected simultaneously with the optical imaging by the respiratory phase detecting section based on the contour of the subject on the optical images. During the optical imaging, a radiation source is controlled by the control section such that radiation rays are emitted to the test subject when the detected respiratory phase corresponds to an intended respiratory phase of the subject.

摘要： A radiation application time upper limit calculator calculates a radiation application time upper limit based on a subject thickness, as measured by a subject thickness measuring unit. While an X-ray tube is controlled according to exposure conditions that have been set in order to apply a radiation X to a breast to capture a radiation image thereof, an X-ray tube controller compares the applied radiation time with the radiation application time upper limit. If the applied radiation time exceeds the radiation application time upper limit, then application of radiation to the subject is interrupted, so as to prevent an inappropriate radiation dosage from being applied to an X-ray detector.
