摘要： A radiation image read-out and reproducing apparatus wherein radiation image read-out and reproduction are carried by use of the same scanning system in the same apparatus. The light beam scanning section includes a read-out main scanning means and a reproducing main scanning means. The light source as well as the light deflector of the read-out main scanning means are the same as the light source and light deflector of the reproducing main scanning means. Further, the means for conveying the stimulable phosphor sheet for read-out and for conveying the recording sheet for reproducing are common to each other. A beam diameter adjusting means adjusts the beam diameter of the light beam between a position on the stimulable phosphor sheet and a position on the recording sheet by moving the beam diameter adjusting means into or away from an optical path of the light beam depending upon whether the light beam scans the stimulable phosphor sheet or the recorded sheet. Also included is an automatic developing machine for carrying out development on the recording sheet carrying the radiation image reproduced thereon.

摘要： A subtraction processing method for radiation images comprises the steps of obtaining a masked image signal by reading out a masked image of an object recorded without injection of contrast media into a specific structure of the object, and obtaining a live image signal by reading out a live image recorded after contrast media have been injected into the specific structure of the object. The parts of the masked image signal and the live image signal corresponding to the same picture elements in the masked and live images are subtracted, thereby obtaining a difference signal for forming an image of the specific structure. In cases where different read-out conditions are used when obtaining the masked image signal and the live image signal, one of the masked image signal or the live image signal is converted into the image signal which would have been obtained if the same read-out conditions had been used for both images. Subtraction processing is then carried out after one of the image signals has been converted.

摘要： A radiation image reproducing apparatus reads a radiation image out of a first recording medium to record it on a second recording medium in a visible form after necessary image processings. Data indicative of a direction of an exposure, either from the front or from the rear of an object, is supplied so that in the case of a rear exposure the radiation image is reproduced on the second recording medium with its lateral position inverted. Data associated with the image processings is recorded in a visible form on the second recording medium together with the radiation image.

摘要： In a radiation image recording system wherein a stimulable phosphor carrying a radiation image stored therein is scanned by stimulating rays to emit light in proportion to the radiation energy stored, and the emitted light is converted to an electric signal which is processed and used to reproduce a visible image in a light-sensitive material, a value within the range of 0.2 to 0.5 and two values at least 0.5 different from each other within the range of 0.4 to 2.6 are selected as the reference optical density values of the reproduced image. An image is once recorded in the light-sensitive material by using reference signals representing the reference values, and the optical densities at the image portions corresponding to the reference values are measured. Differences between the measured values and values on a reference gradation curve are corrected so that the sensitivity is equal to the sensitivity on the reference curve at the portion corresponding to the value selected within the range of 0.2 to 0.5, and the gradient is equal to the gradient on the reference curve with respect to the density value range of 0.4 to 2.6.

摘要： Red, green and blue densities of a color negative are measured at a plurality of points thereon. The measured densities are normalized by a normalizing circuit so that the same levels of density signals can be obtained regardless of the gamma value and sensitivity of the negatives when the same subject matter is photographed under the same conditions. The normalized density signals are plotted in a chromaticity coordinate system and examined as to whether or not they fall within a given region defining a polygon in the coordinate system. The coordinate system is a two dimensional coordinate system in which the axes thereof represent the combinations of two color densities among red, green and blue densities. When the level of the normalized signals with respect to a given point falls within the given region defined by the polygon, the point is determined to have the particular color.

摘要： A method is disclosed for controlling the exposure during photographic printing. The transmission density of a negative or original is measured to provide an exposure control signal. In an illustrative embodiment of this invention, the original is divided into a central portion, a peripheral portion, an upper portion, a lower portion, a right-hand portion and a left-hand portion. Means are provided for quantizing a difference in average density between the portions in the negative, which is classified into a plurality of categories in accordance with a logic of combining characteristic values of the negative. The method affords an enhancement of accuracy in exposure control and an enhancement of probability of obtaining prints of good quality.

摘要： In a radiation image system wherein a stimulable phosphor carrying a radiation image stored therein is exposed to stimulating rays which cause it to emit light in proportion to the radiation energy stored, and the emitted light is detected and converted to an electric signal which is processed to reproduce a visible image, several reference gradation correction curves are created on an orthogonal system of signal level-optical density coordinates. One of the reference curves is selected and rotated around a point on the reference curve on the coordinate system, and/or parallel-shifted on the coordinate system to obtain a desired gradation correction curve.
