摘要： Frequency signals of a plurality of different frequency bands are obtained by transforming each of image signals into a multi-resolution space. Each image signal represents one of radiation images of a single object, which have been formed respectively with a plurality of kinds of radiation having different energy distributions and in which different images of at least part of the object are embedded. Signal components of the frequency signals, which are of an identical frequency band and correspond to different image signals, are weighted with weight factors, which are set in accordance with the frequency band, the signal components representing corresponding picture elements in frequency images represented by the frequency signals. The weighted signal components of the frequency signals are subtracted from one another. Difference signals are thus obtained for the plurality of the different frequency bands. An inverse transform is carried out on the difference signals, and an energy subtraction signal is thereby obtained.

摘要： Radiation images of an object, which have been recorded on recording media and in which different images of at least part of the object are embedded, are read out from the recording media, and a plurality of original image signals, each of which is made up of a series of image signal components, are thereby obtained. The image signal components of the original image signals, which represent corresponding picture elements in the radiation images, are then subtracted from each other, and a difference signal representing an image of a specific structure of the object is thereby obtained. A smoothing process is carried out on an original image signal, and a smoothed image signal is thereby obtained. The image signal components of the original image signal and the difference signal, which represent corresponding picture elements in the images, are weighted such that the weight given to the original image signal may be made larger as the image density represented by the smoothed image signal with respect to a picture element becomes lower. The weighted image signal components are then averaged. A composite image signal obtained from the weighted averaging process is utilized for reproduction of a visible radiation image of the object.

摘要： Digital image signals are detected from radiation images of an object constituted of bones and soft tissues. A subtraction process is carried out with a predetermined parameter on the digital image signals, and a difference signal representing an image of part of the object is obtained. Each of images of a phantom, which has part exhibiting an equivalent radiation absorption coefficient to bones and/or part exhibiting an equivalent radiation absorption coefficient to soft tissues, is read out together with each object image. A value of the parameter is found, with which the image of either part of the phantom becomes erased in a subtraction image of the phantom obtained from subtraction processing. The value of the parameter, which has thus been found, is determined as an optimum value of the parameter. Subtraction processing is then carried out by using the optimum value of the parameter.

摘要： A push-pull printer includes at least one tractor unit thus is formed to have both a pull function and a push function. Fork-like mounting portions are respectively formed at lower portions of a pair of frames provided at both ends of the tractor unit. A pair of tractor guides are located at each of push and pull feed positions of the printer body. Each guide detachably holds a corresponding fork-like mounting portion. When the tractor is to be used in the push type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the push feed position. However, for use in the pull type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the pull feed position. Two such tractors, one providing the pull function and the other the push function, can be used cooperatively.

摘要： A steering sensor is installed in a vehicle by utilizing a clearance between a steering wheel and a turn signal switch assembly. This makes it possible to provide a steering sensor having a high degree of universality, since the sensor can be simply retrofitted on an existing vehicle not already having such a sensor. The steering sensor can be utilized widely in navigation or other systems requiring such a sensor.

摘要： A paper feed apparatus includes a plurality of guide ribs formed on a printer top cover disposed above a platen, the guide ribs being aligned along the axial direction of the platen, and a discharge roller is arranged between each pair of the guide ribs. Each discharge roller has its outer peripheral surface slightly extending toward corresponding guide ribs with respect to guide surfaces of these ribs and cooperating with the ribs to hold the printing paper. When the discharge rollers are driven in synchronism with rotation of the platen, the printing sheets are fed at a speed slightly higher than the paper feed speed of the platen. Therefore, the plurality of printing sheets can be simultaneously fed without causing a deviation therebetween.
