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.

The present invention is an improved barrier-contained radiological sensor holder. In particular, the present invention is directed to radiological sensor holder contained in a barrier to reduce or prevent contamination. The radiological sensor holder preferably comprises a sensor holder at least partly contained within a barrier having a closed end and an open end. The barrier preferably comprises elastomer latex material and the sensor holder preferably comprises a polymer-based material with a treated surface or material characteristics amenable to anchorage of the elastomer. Alternatively, the holder is a wood pulp-based material with naturally coarse or irregular surface characteristics providing anchorage infusion of the elastomer. The sensor holder preferably has a sleeve with a base, first and second sides, and an opposing face and a bite wing integrally formed with the sleeve along a spine on the base. The sensor holder may alternately include an expansion slot along the opposing face.

A radiation imaging apparatus comprises a radiation detection unit configured to convert received radiation into an electrical signal, a communication unit configured to perform wireless communication with an external device, and an exterior at least partially formed by a non-conductive member and configured to contain the radiation detection unit and the communication unit, wherein a conductor is formed so as to cover the radiation detection unit, and the communication unit is arranged between the exterior and the conductor.

A X-ray film packaging bag printer is disclosed. A positioning detection device is arranged above a conveyor belt, positioning holes in an X-ray film packaging bag strip are detected by the positioning detection device, and positioning can be performed by only using adjacent two positioning holes. According to the X-ray film packaging bag printer, the accuracy of the positioning detection device can be improved, the parameter conflict with a set length of a machine can be avoided, that is, the problem of shutdown or hop printing caused by a detection error are effectively avoided; the printing stability and reliability of the X-ray film packaging bag printer are improved; the structure is simple; a printing process is integrated; the automation efficiency is high; the manual operation is reduced; the production efficiency is greatly improved; the production cost is low; the user experience is improved.

A radiation detector includes an image generator and a case. The image generator generates a radiograph according to received radiation. The case stores the image generator and includes a first component and a second component screwed to the first component. The second component is movable with respect to the first component in a direction along a seat surface of a screw by a screw hole of the second component being formed such that a diameter is larger than a diameter of a shaft of the screw but smaller than a diameter of a head of the screw. A loosening torque that acts, in a direction to loosen the screw, on the screw when the seat surface receives a frictional force from the second component is smaller than a loosening start torque that is the loosening torque of when the screw starts to loosen.
