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.

An object comprising a low rare earth mineral photoluminescent structure incorporated onto or into one or more portions of the object, the object being a photoluminescent object is disclosed. Further disclosed is a method for fabricating the object. An object comprising a low rare earth mineral photoluminescent composition incorporated onto or into one or more portions of the object, the object being a photoluminescent object is also disclosed, as well as, a method for fabricating the object.

A method of and system for locating a targeted region in a patient uses a CT imaging subsystem and a radiotherapy subsystem arranged so the targeted region can be imaged with the imaging system and treated with a beam of therapeutic X-ray radiation using a radiotherapy subsystem. The beam of therapeutic X-rays is in a plane that is substantially fixed relative to, and preferably coplanar with, a slice plane of the CT imaging subsystem so that the targeted region can be imaged during a planning phase, and imaged and exposed to the therapeutic X-rays during the treatment phase without the necessity of moving the patient.

Disclosed is a system and method for registering images from two medical imaging modalities in a six-degree-of-freedom coordinate space, for the purpose of providing real time registered imagery for optimization of medical procedures. The system and method uses fiducial that is visible to the first imager and in a fixed position and orientation relative to the second imager. The first imager may be an X-ray device such as a C-arm fluoroscope, and the second imager may be a Transrectal Ultrasound (TRUS) device.

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.
