Abstract: A compact sensor device having stable sensor characteristics and the production method are provided. The sensor device is formed with a sensor substrate and a pair of package substrates bonded to both surface of the sensor substrate. The sensor substrate has a frame with an opening, a movable portion held in the opening to be movable relative to the frame, and a detecting portion for outputting an electric signal according to a positional displacement of the movable portion. Surface-activated regions are formed on the frame of the sensor substrate and the package substrates by use of an atomic beam, an ion beam or a plasma of an inert gas. By forming a direct bonding between the surface-activated regions of the sensor substrate and each of the package substrates at room temperature, it is possible to avoid inconvenience resulting from residual stress at the bonding portion.

Abstract: The present invention relates to an X-ray imaging apparatus using a technique for preventing artifacts appearing in 3D X-ray images. The technique involves subtraction images obtained by an energy subtraction unit serving as the basis for a 3D reconstruction process for acquiring a 3D X-ray image selectively showing a site of interest in a patient. The technique also involves an image subtraction process carried out by the energy subtraction unit according to weights set by a weight setter which selects only the site of interest in the patient, and eliminates soft tissue forming a background around the site of interest. As a result, even if body motion occurs with the soft tissue forming the background around the site of interest of the patient while subtraction images are acquired one after another by the energy subtraction unit, the body motion in the soft tissue of the patient never appears as artifacts on the subtraction images, or on a 3D X-ray image acquired on the basis of the subtraction images.
