    Abstract: Embodiments describe an accurate and rapid method for assessing spinal bone density on chest or abdominal CT images using post-processed colored images. Post-processing of CT images for the purposes of displaying the spine is followed by color enhancement of routine unenhanced or contrast enhanced CT images to improve diagnostic accuracy, inter-observer agreement, reader confidence and/or time of interpretation as it relates to assessing bone density of the spine. CT images are post-processed (without changes to the standard-of-care CT imaging protocol and without additional cost or radiation for the patient) to straighten the spine for improved visualization of multiple segments. The color-enhanced images can be displayable simultaneously with the grayscale images. Methods and systems are provided for performing opportunistic bone density screening.

  • Publication number: 20140139215
    Abstract: An imaging system and methods including a gantry defining a bore and an imaging axis extending through the bore, and at least one support member that supports the gantry such that the imaging axis has a generally vertical orientation, where the gantry is displaceable with respect to the at least one support member in a generally vertical direction. The imaging system may be configured to obtain a vertical imaging scan (e.g., a helical x-ray CT scan), of a patient in a weight-bearing position. The gantry may be rotatable between a first position, in which the gantry is supported such that the imaging axis has a generally vertical orientation, and a second position, such that the imaging axis has a generally horizontal orientation. The gantry may be displaceable in a horizontal direction and the system may perform a horizontal scan of a patient or object positioned within the bore.

  • Patent number: 8731634
    Abstract: A medical imaging system for imaging a region of interest (ROI) in a patient. The imaging system includes an imaging modality unit having a field of view (FOV) and an examination platform. The examination platform has a pair of opposite ends and a platform surface extending therebetween along an examination axis. The platform surface extends into the FOV. The imaging system also includes a patient transport belt that is supported by the examination platform and extends along the platform surface between the ends of the examination platform. The imaging system also includes a motor that is operatively coupled to and configured to move the transport belt along the platform surface in a direction along the examination axis. The motor moves the transport belt so that a predetermined portion of the transport belt is within the FOV.

  • Patent number: 8525833
    Abstract: A method of generating a three-dimensional volumetric representation of a subject. The method includes capturing a first image of the subject with a first capture device from a first perspective, accessing a stored volumetric model of the subject, and approximating a first orientation of the stored volumetric model that corresponds to the first perspective. A digitally simulated radiograph is generated from the stored volumetric model and compared to the captured first image. A second image is also captured at the same time as the first picture, but from a different perspective. A second orientation of the stored volumetric model is approximated that corresponds to the second image. A second digitally simulated radiograph is generated and compared to the second image. Based on the approximated orientations, a three-dimensional volumetric representation of the subject is generated by positioning the stored volumetric model according to the first orientation and the second orientation.

  • Publication number: 20130114797
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes at least a tabletop support, an arm, a position storing unit, and a mechanism controlling unit. The tabletop support supports a tabletop movably in a longitudinal direction, a raising/reclining direction, and an upper/lower direction of the tabletop. The arm holds an X-ray tube and an X-ray detector movably in an approaching/separating direction with respect to the tabletop support. The position storing unit stores a photographing position of the arm and a photographing position of the tabletop in association with each other. When the arm is at a retraction position, the mechanism controlling unit moves the tabletop in the raising/reclining direction and the upper/lower direction to maintain a position in at least the upper/lower direction of a region of the object corresponding to a photographing position of the arm stored by the position storing unit.

    Abstract: The invention comprises intensity control of a charged particle beam acceleration, extraction, and/or targeting method and apparatus used in conjunction with charged particle beam radiation therapy of cancerous tumors. Particularly, intensity of a charged particle stream of a synchrotron is described. Intensity control is described in combination with turning magnets, edge focusing magnets, concentrating magnetic field magnets, winding and control coils, and extraction elements of the synchrotron. The system reduces the overall size of the synchrotron, provides a tightly controlled proton beam, directly reduces the size of required magnetic fields, directly reduces required operating power, and allows continual acceleration of protons in a synchrotron even during a process of extracting protons from the synchrotron.
