Abstract: An imaging system includes components to allow the system to be compact, highly transportable, and capture images in non-conventional settings. An imaging device includes an exoskeleton configured to house and provide structural support for an x-ray source and a detector and a spindle structure protruding from an outer surface of the exoskeleton. The imaging device also includes an x-ray source and a detector affixed to an internal surface of the exoskeleton and a rotation motor configured to rotate the exoskeleton about the spindle structure.

Abstract: An imaging device includes a rotatable gantry having opposing sides, wherein the gantry is rotatable about an axis of rotation, an x-ray source mounted to the gantry, an x-ray detector mounted to the gantry opposite the x-ray source, and one or more ultraviolet light sources mounted to one of the gantry, the x-ray source, and the x-ray detector.

Abstract: A surgical navigation system. The surgical navigation system can include a computing device having a non-transitory computer-readable medium for storing surgical navigation software, and a processor adapted to execute the software, a headgear unit communicatively coupled to the computing device, the headgear unit including at least one camera. The system can further include at least one fiducial marker, the fiducial marker having a complex configuration, wherein the configuration of the fiducial marker is adapted to present a unique view of the fiducial marker to the at least one camera based on the angle between the camera and the fiducial marker, and wherein the surgical navigation software is adapted to determine the position of the fiducial marker in three-dimensional space based on the unique view of the fiducial marker.

Abstract: A surgical imaging system includes a CT scanner and an image exchange system. A computer interfaces with an image exchange server over the Internet or over another wide area network. The image exchange server provides an offsite backup of images, provides a complete project management for medical procedures involving the images, and provides software available for trial and purchase for use on the surgical imaging system or other computers.

Abstract: A surgeon selects a volume of interest by placing an untracked “marker” in a patient near an area where an update is desired. During surgery, when an updated CT scan is requested, the CT scanner performs a scan of the patient using a full field of view to take a series of two-dimensional initial images of the patient from a plurality of angularly spaced positions about the patient. The position of the untracked marker is determined by the CT scanner in or more of the initial images. The volume of interest is defined as the position of the untracked marker, plus some margin. The CT scanner then collimates the x-ray source to scan only the volume of interest. The CT scanner then completes the update scan of the volume of interest and updates a previous CT scan(s) to create a fully updated CT image, reducing x-ray exposure of the patient.

Abstract: A CT scanner automatically determines a volume of change based upon anatomical changes in a patient. During surgery, the CT scanner takes a sufficient number of two-dimensional initial images using a full field of view. The CT scanner compares the initial images to pre-operative data. Based upon the comparison, the CT scanner automatically determines the volume of change plus some margin to define a volume of interest. The CT scanner then collimates an x-ray source to perform an intra-operative updated CT scan of the volume of interest. The CT scanner updates the pre-operative data with the data from the intra-operative updated CT scan of the volume of interest to form a fully updated three-dimensional CT image. The initial images and the pre-operative data can be taken at a lower resolution than the intra-operative updated CT scan of the volume of interest to reduce the x-ray exposure of the patient.
