    • An image processing apparatus of the disclosure performs image processing to an extraction image as an image of an extracted linear configuration appearing in an original image. Specifically, the image processing apparatus includes a line connecting processor configured to connect fragments of the linear configuration in the extraction image due to noises or the like to generate a fragment eliminated image. The line connecting processor interpolates pixels in the extraction image in an extending direction of the linear configuration based on a direction image while obtaining the extending direction of the linear configuration in the extraction image. Accordingly, the linear configuration is expanded in its extending direction. Such operation causes natural connection of the fragments of the linear configuration in the extraction image, achieving provision of an image with higher visibility.

    • An ink tank is attachable to the attachment section by positioning first engagement sections at first fitting sections on the attachment section and then locking a second engagement section to a second fitting section of the attachment section by rotating the tank. The multiple supply ports are arranged on a bottom face of the tank such that the supply ports are on both sides of a center line in a width direction of the tank, and that distances between each of abutting centers configured to abut ink receiving parts of the attachment section, and the first engagement section side in a direction along a center line are mutually different. It is possible to avoid reception of a reactive force to the ink receiving parts at one time when rotating and attaching the tank, and to achieve stable attachment while suppressing excessive inclination of the tank at the time of attachment.

    • This invention has one object to provide radiographic apparatus with a compensating filter that allows simple and accurate estimation of direct radiation to acquire a radioscopic image or a sectional image of excellent contrast. This invention includes a direct-ray attenuation-rate acquiring section for acquiring a direct-ray attenuation rate from a dose of direct radiation entering into a subject and a dose of direct radiation emitted from the subject. In this invention, a direct-ray attenuation rate is acquired on an assumption that a primary indirect-ray attenuation rate is equal to the direct-ray attenuation rate, the primary indirect-ray attenuation rate being a rate of decreasing a primary indirect-ray generated with the compensating filter that transmits the subject. Such configuration may achieve provision of X-ray apparatus that allows more simple acquisition of a fluoroscopic X-ray image or a sectional image without performing complicated calculations conventionally.
