    摘要： An apparatus for computer aided diagnosis of images comprises an entire area image memory for storing an entire area image signal representing a radiation image of an object, and a prospective abnormal pattern detecting device for detecting a prospective abnormal pattern in the radiation image in accordance with the entire area image signal. A judgment device makes a judgment as to the presence or absence of the prospective abnormal pattern in accordance with the results of the detection of the prospective abnormal pattern carried out by the prospective abnormal pattern detecting device. In cases where the judgment device has judged that the prospective abnormal pattern is present, a local area extracting device extracts a local area limited image signal corresponding to a local area containing the prospective abnormal pattern from the entire area image signal having been stored in the entire area image memory. A local area limited image displaying device displays the image of the local area in accordance with the local area limited image signal, which has been extracted by the local area extracting device. An entire area image displaying device displays the entire area of the radiation image of the object in accordance with the entire area image signal.

    摘要： A system in which an editing server (10) and a lot of client computers (1) are capable of communicating with one another, and an edited image can be generated by the plurality of client computers. When image data is transmitted from the image server to the client computer, the resolution of image data to be transmitted is reduced in correspondence with the resolution of a monitor display device connected to the client computer. Further, the number of colors of an image represented by the image data is decreased in correspondence with the number of colors which can be displayed on the monitor display device. The data quantity of the image data to be transmitted is reduced, so that time required to transmit the image data is shortened. A user image to be synthesized on a template image is read in the client computer. Image data representing the template image used for the image synthesis and image data representing a mask image are transmitted from the main image server to the client computer. In the client computer, image synthesis processing is performed. Image data representing an area required for image synthesis of the user image used for the image synthesis is extracted. The extracted user image data and synthesis information required for the synthesis are transmitted from the client computer to the main image server, where a composite image is printed. A lot of client computers and an editing server are connected to one another via an internet. One of the client computers generates an edited image, and another client computer reedits the generated edited image. The process of the editing can be also confirmed on a display screen by a client computer which does not relate to the editing.

    摘要： Reference regions are set in a radiation image, which serves as a reference among a plurality of radiation images, and template regions are set in the other radiation images. An orthogonal coordinate system is defined on each of the plurality of the radiation images. First template matching is carried out in order to match the template regions to the reference regions. Factors of affine transformation are calculated, and first affine transformation is carried out, with which at least the correction with a rotating operation and the correction with an enlargement or reduction factor are carried out on the radiation images containing the template regions. Second template matching is then carried out on the radiation images, which have been obtained from the first affine transformation. The factors of affine transformation are calculated, and second affine transformation is then carried out, with which the correction with the rotating operation, the correction with the enlargement or reduction factor, and the correction with a parallel translation are carried out on the radiation images containing the template regions.

    摘要： With a method for compressing a dynamic range of an image, an original image signal Sorg representing an original image is processed, and a processed image signal Sproc representing an image having a narrower dynamic range than the original image is thereby generated. The method comprises the steps of calculating the value of an unsharp mask signal Sus corresponding to each of picture elements in the original image by averaging the values of image signal components of the original image signal Sorg, which image signal components represent the picture elements belonging to a predetermined region surrounding each picture element. Values of the processed image signal Sproc are calculated with the formula Sproc = Sorg + f1(Sus)
    where f1(Sus) represents a function, the value of which decreases monotonously as the value of the unsharp mask signal Sus increases. Alternatively, in lieu of the function f1(Sus), a function f2(Sus) is employed, the value of which decreases monotonously as the value of the unsharp mask signal Sus increases, and the differential coefficient of which is continuous.
