A bone shape measuring system measures the shape of bone to be supplemented by artificial bone on the basis of bone image data representing an image including the bone to be supplemented by artificial bone. A prospective template selection system selects at least one template the shape of which substantially conforms to the shape of the bone to be supplemented by artificial bone as measured by the bone shape measuring system out of the plurality of templates represented by the template data.

A portable radiation imaging system is provided which is capable of always performing imaging in a state where the tilt of the radiation emitted from a radiation source in relation to the detection surface of an image detection device is substantially perpendicular. The system is equipped with a tilt adjustment means that makes the tilt of the radiation in relation to the detection surface of a radiation image detection device substantially perpendicular by changing the tilt angle of a radiation source based on an angular signal representing the degree of tilt of the radiation in relation to said detection surface output by an angular signal output means, and a command means that generates an exposure command to the radiation source when the tilt of the radiation to be emitted from said radiation source in relation to the detection surface of said radiation image detection device is substantially perpendicular.

At least one kind of image input modality and at least one kind of image information output device are connected to an image processing system. At least one kind of image input modality, which is among connected image input modalities, includes a plurality of image information input apparatuses having different input device characteristics. The image processing system comprises a standardization device for carrying out transform processing on image information such that, in every case where the image information has been received from one image information input apparatus, which is among the plurality of the image information input apparatuses, the received image information may be transformed into standard image information, which does not depend upon the input device characteristics of the one image information input apparatus and depends upon standard device characteristics having been set previously for the image input modality including the one image information input apparatus.

A radiation image detecting system includes a solid radiation detector made up of a plurality of solid radiation detecting elements which are two-dimensionally arranged and convert radiations bearing thereon image information to an image signal. An A/D convertor converts the image signal as output from the solid radiation detector to a digital image signal. The digital image signal is analyzed and a characteristic of standardization processing which is to be carried out on the digital image signal is determined. A standardization processing circuit carries out standardization processing on the digital image signal according to the characteristic of standardization processing determined.

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.
