Abstract: A recording method of a medical image comprising: jetting ink onto a recording medium to make the medical image, wherein a reflection density vs. transmission density characteristic curve of the recorded medical image is monotone non-decreasing in the range of the transmission density being not more than 2.

Abstract: An image recording method for visualizing an image signal of medical diagnosis, which has the steps of: inputting the image signal of medical diagnosis; processing the image signal of medical diagnosis to get correct sharpness in visualized image by applying a frequency enhancement processing; and visualizing the image signal of medical diagnosis by conducting an ink-jetting process to form an image on a recording medium based on a processed image signal, wherein the ink-jetting process has a characteristic such that sharpness of a visualized image varies in relation with a density of the visualized image; wherein degree of enhancement in the frequency enhancement processing is determined according to a density of visualized image.

Abstract: There is described a medical image recording apparatus, which records a medical image on a recording medium based on image data. The apparatus includes an ink-jetting head to emit ink particles onto the recording medium and a controlling section to control the ink-jetting head, so that a total amount of the ink particles per unit area, emitted by the ink-jetting head and adhered onto the recording medium, is maintained at substantially a constant value even if density of a solid-tone image area varies within density range D. With respect to at least one of combinations of values k1, k2 selected under conditions of 0≦k1<1, 0<k2<1.0, and k1<k2, the density range D fulfils the equation of Dmin+k1(Dmax−Dmin)≦D≦Dmin+k2(Dmax−Dmin), where, Dmax is a recordable maximum-density, and Dmin is a recordable minimum-density.

Abstract: A method of recording a transmission image composed of dots on a recording medium having the steps of; moving a recording medium in a sub-scanning direction, and moving a recording head relatively with respect to the recording medium in a main scanning direction which is crossing the sub-scanning direction, wherein a diameter D of a dot recorded on said recording medium falls within a range expressed by 1.

Abstract: The invention concerns an image recording apparatus suitable for forming a medical image that is used for a medical diagnosis, and a test pattern for evaluating a quality of the medical image. The image recording apparatus includes a printing section to either the medical image or the test pattern on the recording medium, based on image date; a printing-condition setting section to set a printing condition for printing the test pattern; and a printing-condition displaying section to display the printing condition set by the printing-condition setting section. The printing section prints at least one of a sharpness-evaluating pattern and a granularity-evaluating pattern.

Abstract: The method and apparatus for correcting the dynamic balance of a rotating body, whereby the correction of the dynamic balance of a rotating body is achieved by fixing a correcting agent on the rotating body after the position of the dynamic unbalance and the amount of the dynamic unbalance in the rotating body are measured, are so constructed as to detect whether or not the correcting agent fixed on the rotating body is protruding from a prescribed configuration of the rotating body. Therefore, the method and the apparatus are capable of not only correcting a dynamic unbalance of a rotating body, but also detecting the protrusion of the correcting agent fixed on the rotating body.

Abstract: Disclosed is a photosensitive material which has a first photosensitive layer formed on a support body such as an aluminum plate, a peel-off layer thereon and a second photosensitive layer formed on the peel-off layer in such a manner that the second layer can be photographically exposed to light and photographically developed independently from the first photosensitive layer and the first photosensitive layer may be subsequently photographically exposed with the picture image formed on the second photosensitive layer acting as a photographic mask. After the first photosensitive layer has been photographically developed, the two photosensitive layers may be used for different purposes, for instance, using the first photosensitive layer as a printing plate and the second photosensitive layer as a photographic film for making duplicate printing plates.
