A virtual control system for an operating room establishes virtual control devices to control surgical equipment and patient monitoring equipment and to display control, status and functionality information concerning the surgical equipment and condition information of the patient. The virtual control devices permit direct interaction by the surgeon while maintaining a sterile field, and avoid the use of actual physical devices and electrical cables connecting them to the surgical equipment.

A intra-oral laser digitizer system provides a three-dimensional visual image of a real-world object such as a dental item through a laser digitization. The laser digitizer captures an image of the object by scanning multiple portions of the object in an exposure period. The intra-oral digitizer may be inserted into an oral cavity (in vivo) to capture an image of a dental item such as a tooth, multiple teeth or dentition. The captured image is processed to generate the three-dimension visual image.

A method and apparatus for Cone-Beam Computerized Tomography, (CBCT) is configured to increase the maximum Field-Of-View (FOV) through a composite scanning protocol and includes acquisition and reconstruction of multiple volumes related to partially overlapping different anatomic areas, and the subsequent stitching of those volumes, thereby obtaining, as a final result, a single final volume having dimensions larger than those otherwise provided by the geometry of the acquisition system.

Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms. This portability feature can be particularly useful in multi-suite medical and dental offices where a single x-ray device can be used as a digital x-ray camera in multiple offices instead of requiring a separate device in every office.

A radiation-recording plate (104) can be constructed and arranged to form an image upon exposure from both a front side and a back side. The plate can include a marker (201) detectable in the image (205) after exposure and indicative of which of the front side and the back side the plate is exposed from. The marker may comprise a medium opaque to the radiation coating a region that does not interfere with reading the image when the plate is exposed from either side, or may be a void in the sensitive layer of the plate. The marker may have horizontal asymmetry about a vertical axis relative to a normal image orientation, or the marker may have vertical asymmetry about a horizontal axis relative to a normal image orientation. The marker may further comprise a front side marker and a back side marker whose appearance in an image on the plate indicates exposure from the front side or the back side respectively. A method of identifying a side from which a radiation-recording plate has been exposed to radiation may comprise: incorporating in the plate (104), in a position that substantially does not interfere with an image area of the plate, a marker (201) whose appearance in the image identifies which side the plate is exposed from; exposing the plate to the radiation; and observing the image (205) for the identification of the side of the plate exposed. A method of making a radiation sensitive plate having at least one radiation sensitive layer may comprise: providing a film sensitive to the radiation on a first side of the radiation sensitive plate; and applying a suspension of a heavy metal in a binder to a region of a second side of the radiation sensitive layer.

A method for producing an artifact-corrected image of a negative jaw impression in a recipient jaw comprising, forming a negative impression of said recipient jaw, producing a first digital image of said negative jaw impression, producing a second digital image, including said artifacts of said negative jaw impression in said recipient jaw and using said first digital image to produce an artifact-corrected computer representation of said negative impression in said recipient jaw.

A multi-layer dental panoramic and transverse x-ray imaging system includes an x-ray source; a digital imaging device capable of frame mode output with a sufficient frame rate; a mechanical manipulator having at least one rotational axis located in a position other than the focal point of the x-ray source; a position detection mechanism for detecting the camera position in 1D, 2D or 3D depending of the complexity of the trajectory; a final image reconstruction mechanism for reconstructing the final images out of the stored frames; a real time storage system such as RAM, hard drive or an drive array able to store all the frames captured during an exposure; and a digital processing unit capable of executing the reconstruction algorithm, such components being interconnected in operational arrangement. The system produces selectively dental panoramic x-ray images, dental transverse x-ray images and dental tomosynthetic 3D images from a frame stream produced by a high-speed, x-ray digital imaging device.
