An X-ray imaging apparatus includes a sensor panel that converts incident radiation to an electric signal, a tabular metallic base plate including a front surface where the sensor panel is supported and a region where the tabular metallic base plate has a basic thickness, a circuit board disposed on a rear surface of the tabular metallic base plate, the rear surface being opposite to the front surface, wherein a thickness of the tabular metallic base plate in a region where the circuit board is disposed is larger than the basic thickness.

Provided is a method for manufacturing a housing of a radiation detection cassette that can appropriately form a recess without a housing material depositing on an end mill or the like, in a case where a recess is formed by working the housing material formed of an alloy containing Mg and Li. A method for manufacturing a housing of a radiation detection cassette that houses a radiation detector in the housing includes preparing a housing material that is formed of an alloy containing Mg and Li and contains 0.1 mass % or more of Li, forming a recess using a working method other than cutting work on a surface of the housing material, and performing cutting work on the formed recess to shape the recess.

A radiographing apparatus includes a support base and a housing. The support base includes a base side protruding portion that protrudes towards a bottom surface of the housing. The housing includes a housing side protruding portion that protrudes in a direction toward the support base. A first gap and a second gap are formed between the base side protruding portion and the housing side protruding portion in a perpendicular direction with respect to an incident direction of radiation at different positions. The first gap and the second gap are different from each other in distance in the perpendicular direction between the base side protruding portion and the housing side protruding portion.

An IP cover having a light-shielding property is detachably mounted on an IP. The IP includes a stimulable phosphor layer on one surface thereof. The IP cover is mounted on the stimulable phosphor layer so as to be closely attached to the stimulable phosphor layer. The IP and the IP cover include notches, and a part of an inspection target is inserted into the notches at the time of inspection. An IP unit is mounted on a blade welded portion of an impeller. Radiation is applied from a radiation irradiation device and a radiation image of the blade welded portion is recorded on the IP as a latent image. The IP cover is detached from the IP unit and the IP is set on a template. The IP is set at an image reading position of a radiation image reading device by the template, and the radiation image is read.

A radiographing apparatus includes a radiation detection panel including an effective image-acquisition area configured to detect radiation and a casing configured to house the radiation detection panel. The casing includes an incidence surface on which the radiation is incident, a back surface opposite the incidence surface, and a side surface between the incidence surface and the back surface. On the side surface of the casing, a level-difference portion indicating a position based on the effective image-acquisition area and a protrusion protruding more outward than the level-difference portion are provided.

An intra-oral X-ray imaging system according to an embodiment of the present disclosure includes an intra-oral X-ray sensing device being shaped in such a manner as to be hand-gripped by an user and performing X-ray imaging within an oral cavity through X-ray radiation, a charging connection deck having a structure where the intra-oral X-ray sensing device is accommodated therein and is chargeable, the charging connection deck being electrically connected to the intra-oral X-ray sensing device when the intra-oral X-ray sensing device is accommodated, and an X-ray image generation and display device being electrically connected to the charging connection deck, image-processing X-ray data resulting from the X-ray imaging, generating an X-ray image as a result of the image-processing, and displaying the generated X-ray image for a user's viewing, wherein the X-ray image generation and display device receives the X-ray data resulting from the X-ray imaging, through the charging connection deck.

Systems, devices, and methods are described for providing, among other things, an intra-oral x-ray imaging system configured to reduce patient exposure to x-rays, reduce amount of scatter, transmission, or re-radiation during imaging, or improve x-ray image quality. In an embodiment, an intra-oral x-ray imaging system includes an intra-oral x-ray sensor configured to communicate intra-oral x-ray sensor position information or intra-oral x-ray sensor orientation information to a remote x-ray source.

In a radiation imaging apparatus, a first recessed portion is formed in at least one side surface among a plurality of side surfaces forming a frame body of a casing. Moreover, a second recessed portion is formed in a peripheral region of a back surface of a back-surface housing, which is a region opposite to the first recessed portion with respect to a boundary between the back surface and the at least one side surface of the casing including the first recessed portion.

A method for producing a holding apparatus for an x-ray film for teeth of a patient. The method includes performing an image registration of a first two-dimensional x-ray image of a tooth of an upper or lower jaw in a three-dimensional volume-tomographic data record of a jaw with a computer, determining a relative position of the first two-dimensional x-ray image within the three-dimensional volume-tomographic data record, preparing a virtual model for a holding apparatus that is attachable to the teeth of the upper or lower jaw in an interlocking fashion on the basis of the three-dimensional volume-tomographic data record, and producing the holding apparatus based on the virtual model. The holding apparatus includes a holding element which holds the x-ray film in a defined position. The defined position is established by the relative position of the first two-dimensional x-ray image in the three-dimensional volume-tomographic data record.
