A dental x-ray sensor holder and sheath for affixing a sensor to a backing plate of the holder. The dental x-ray sensor holder and sheath generally includes a sensor holder with a backing plate, having one or more spring arms, and affixed to or formed contiguously with a proximal end of a bite block of the holder. It also includes a sensor sheath adapted to secure a sensor to the backing plate for X-ray acquisition.

Methods and systems are described for operating an intra-oral imaging sensor that includes a housing, an image sensing component configured to capture image data while the intra-oral imaging sensor housing is positioned in a mouth of a patient, and a multi-dimensional sensor positioned within the housing of the intra-oral imaging sensor. An electronic controller is configured to receive data from the multi-dimensional sensor and to control an action of the intra-oral imaging sensor based on the data received from the multi-dimensional sensor.

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.

An x-ray phosphor plate system has an x-ray phosphor plate, which is configured to be exposed by x-ray light in a recording region, and which carries a shadowing marker, which is arranged in the recording region, on at least one side of the x-ray phosphor plate. The system also has a phosphor plate reader, which is configured to read the exposed x-ray phosphor plate in order to produce an x-ray recording. The shadowing marker has a shadowing effect in respect of x-ray light that is so small that the shadowing marker is only weakly identifiable, and/or only identifiable by way of image artefacts, and/or not identifiable when the x-ray recording is observed by a user. The phosphor plate reader instead has an identification algorithm, which is configured to identify whether or not the x-ray light was shadowed by the shadowing marker during the exposure.

A dental x-ray sensor holder 1 and sheath 4 for affixing a sensor to a backing plate 2 of the holder 1. The dental x-ray sensor holder 1 and sheath 4 generally includes a sensor holder 1 with a backing plate 2, having one or more spring arms 3, and affixed to or formed contiguously with a proximal end of a bite block 9 of the holder 1. It also includes a sensor sheath adapted to secure a sensor to the backing plate for X-ray acquisition.

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.

A dental radiographic positioner and film holder assembly has a film plane reference component (2) configured to detachably affix to a shaft (1a) extending from the edge of the film holder (1). Affixing surfaces (1b, 2b) are provided between the shaft (1a) and film plane (2) to enable longitudinal movement and restrict rotational movement. A teeth plane reference component (3) is detachably affixed to the shaft (1a). A bisecting angle reference component (4) is detachably affixed to the shaft (1a). Both the bisecting angle plane (4) and teeth plane (3) are attached to allow for longitudinal motion along the shaft (1a) as well as rotational motion around the axis of the shaft (1a).

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 dental imaging system may include an X-ray source, a first optical alignment device, and a dental image collection device. The dental image collection device may include a mouthpiece, at least one electronic X-ray sensor carried by the mouthpiece, and a second optical alignment device carried by the mouthpiece and cooperating with the first optical alignment device to facilitate optically aligning the mouthpiece with the X-ray source. The system may also include a dental image processing device coupled to the at least one electronic X-ray sensor.

An intra-oral dental radiological image sensor is mechanically reinforced by two front R.sub.A and rear R.sub.B mechanical reinforcing plates each inserted between a respective face of an image capture module and a respective front 20A and rear 20B shell bottom of a casing. The front reinforcing plate is a solid plate, made of material transparent to X rays, covering the photosensitive front face (scintillator) of the module, and harder than the front shell. The rear plate, less thick than the front plate, is harder than the rear shell and comprises an opening O provided to surround, without covering them, components present on the rear face of the module, under a rear shell dome.
