    摘要: A plurality of radiation image signals, which represent radiation images of an object, are obtained by irradiating radiation from different directions to the object and detecting the radiation carrying image information of the object via a scattered radiation removing device for removing radiation having been scattered by the object. Image signal components representing a pattern of the scattered radiation removing device, which are contained in the radiation image signals, are reduced, and pattern-reduced radiation image signals, in which the image signal components representing the pattern of the scattered radiation removing device have been reduced, are thereby obtained. At least either one of a volume signal and a tomographic image signal representing an image of the object is then obtained from the pattern-reduced radiation image signals.

    摘要: A first image signal representing a radiation image of an object is obtained by exposing a stimulable phosphor sheet, on which the radiation image has been stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, the emitted light being detected. A second image signal representing the radiation image is thereafter obtained by again exposing the stimulable phosphor sheet to stimulating rays, the light emitted by the stimulable phosphor sheet being detected. Read-out conditions, under which the second image signal is to be obtained, and/or image processing conditions, under which the second image signal having been obtained is to be image processed, are adjusted on the basis of the first image signal. A storage device stores information representing a standard pattern of radiation images. A signal transforming device transforms the first image signal representing the radiation image into a transformed image signal representing the radiation image, which has been transformed into the standard pattern. A condition adjuster is provided with a neural network, which receives the transformed image signal and feeds out information representing the read-out conditions and/or the image processing conditions.

    摘要: From an image signal made up of a series of image signal components representing a radiation image, an abnormal pattern appearing as an approximately circular pattern in the radiation image is detected. A first finding device finds a prospective abnormal pattern appearing in the radiation image by processing the image signal with a first filter capable of finding an approximately circular pattern. A second finding device finds a linear pattern appearing in the radiation image by processing the image signal with a second filter capable of finding a linear pattern or a linear pattern the width and the length of which are approximately equal to each other. A judgment device selects an enlarged prospective abnormal pattern region in an image area, in which both the prospective abnormal pattern and the linear pattern have been found, the enlarged prospective abnormal pattern region including the prospective abnormal pattern and extending to parts around the prospective abnormal pattern. The area and the maximum width of the linear pattern falling within the enlarged prospective abnormal pattern region are then calculated. From the area and the maximum width of the linear pattern, a judgment is made as to whether the prospective abnormal pattern is or is not a true abnormal pattern.
