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： In energy subtraction processing, a filter for filtering out radiation having a low energy level is located between first and second recording media. Radiation, which has passed through an object, is irradiated from the side of the first recording medium such that only the radiation having a high energy level may impinge upon the second recording medium, radiation images of the object being thereby recorded on the two recording media. Image signals representing the radiation images are subtracted from each other, and an image signal representing an energy subtraction image is thereby obtained. The subtraction process is not carried out on high frequency components of the image signals representing the radiation images and is carried out only on low frequency components of the image signals such that an image signal representing an energy subtraction image having improved graininess may be obtained. A stimulable phosphor sheet is utilized as the filter for filtering out radiation having a low energy level. High frequency components of an image signal, which represents image information stored on the stimulable phosphor sheet, are added to the image signal representing the energy subtraction image, and an image signal representing an energy subtraction image, the graininess of which has been improved even further, is thereby obtained.

摘要： A method of recognizing a subdivision pattern of radiation images comprises the steps of, in the case where subdivision image recording has been carried out by exposing each of a plurality of predetermined subdivisions on a stimulable phosphor sheet to radiation, detecting prospective edge points, which are considered to be an edge of a subdivision line between the subdivisions, from image signals detected from a stimulable phosphor sheet region as the boundary between the subdivisions, and discriminating whether the prospective edge points stand or do not stand in a straight line. An image subdivision pattern on the stimulable phosphor sheet is recognized by judging that the subdivision line is present in the case where the prospective edge points stand in a straight line, and judging that no subdivision line is present in the case where the prospective edge points do not stand in a straight line.

摘要： Predictive errors are grouped into a plurality of quantizing ranges, and the predictive errors in the respective quantizing ranges are represented by representative quantizing values assigned respectively to the quantizing ranges. The predictive error data items in each of the quantizing ranges are processed to provide a weighted mean value based on the frequency distribution thereto. The weighted mean value or a value close thereto is used as a representative quantized value for that quantizing range.

摘要： A method of compressing image signals comprises the step of dividing the image signals into main signals sampled at appropriate intervals and interpolation signals other than the main signals. As for said main signals, prediction encoding compression processing is carried out between the main signals. As for the interpolation signals, prediction encoding compression processing is carried out based on the main signals. At least for the interpolation signals, quantization processing for making the bit resolution coarse is carried out in the course of encoding. The quantization processing of the interpolation signals is carried out for making the bit resolution coarser than the bit resolution of the main signals.

摘要： An electrodynamic transducer comprising a source of magnetic flux and poles that define an annular gap in the flux path to obtain a radially oriented and uniformly distributed magnetic flux across the gap. Coils are mounted on a support that pivots universally about a center concentric with the gap. The coils are placed on the support so that pivotal movement of the latter causes a change in flux linkage with the coils. The coils are wound in such a manner that the electric potentials generated in diametrically opposite coils are added together. There may be sets of mutually perpendicular coils.

摘要： An measurement processing apparatus for efficiently measuring geometric data of an image is provided. A reference-image outputting means forms a reference-image based on an image that has been previously measured as well as a setting order data which indicates a suggestion as to the order in which the measuring points should be set and which shows the same setting order in which the measuring points were set for a previously performed measurement of a past-measurement image, and outputs the reference-image and the setting order data to an image display means. While consulting the reference-image and the setting order data displayed on the image display means, an operator can set, by use of a measuring point setting means, the measuring points at the correct positions and in the correct order in the subject image displayed on a display screen, and the geometrical data can be measured automatically and efficiently.
