Patent number: 9689811Abstract: A scanning transmission x-ray imaging system includes an x-ray source producing x-rays at a focal spot and moving about a source movement axis passing through the focal spot, x-ray detector arrays each detecting x-rays from the x-ray source along a detector dimension, and a collimator between the source and the arrays, fixed to the source, and defining slits to collimate the x-rays into a set of linear x-ray beams. The arrays are spaced from the source such that the linear x-ray beam at each of the arrays has the linear x-ray beam substantially impact within a height and width of a respective one of the arrays. The arrays move correspondingly with the source such that each of the linear x-ray beams remain aligned with a respective one of the arrays.Type: GrantFiled: June 26, 2015Date of Patent: June 27, 2017Assignee: Visuum, LLCInventors: John D. Cox, James Gimlett, Shaun Georges, David Cleaves

Patent number: 9513385Abstract: An x-ray scanner includes an x-ray source producing a fan beam of x-rays, an x-ray detector array, a collimator, a second motor moving TDI detector arrays, and an x-ray processing unit. The detector array has the TDI arrays and detects x-rays from the source. The collimator disposed between the source and detector array defines slits to collimate the fan beam of x-rays into lateral beams with a height dimension the same as a height dimension of the TDI detector arrays. Either the collimator is fixed to the x-ray source or moves thereto. A first motor moves the collimator or the collimator and source together. The processing unit controls the motors, processes detection of the x-rays, and forms an image of an entity between the collimator and the detector array to have an intensity and contrast of the scanned image be maximized while an exposure dose for the entity is minimized.Type: GrantFiled: February 5, 2015Date of Patent: December 6, 2016Assignee: Visuum, LLCInventor: John D.

Patent number: 9121809Abstract: An x-ray scanner includes an x-ray source producing a fan of x-rays, an x-ray detector array, a collimator disposed between the source and the array, fixed to the source, and defining a slit collimating the fan of x-rays into a linear x-ray beam. The array is spaced from the source such that a linear extent of the linear x-ray beam is no greater than a detector dimension of the array. An x-ray processing unit processes detection of the linear x-ray beam by the array. A processor-controlled motor moves the x-ray source about a source movement axis to pan the linear x-ray beam and create an x-ray emission cone and moves the array correspondingly with the source. The x-ray processing unit form an x-ray scanned image of an object disposed between the collimator and the array within the x-ray emission cone when the linear x-ray beam is panned across the object.Type: GrantFiled: November 16, 2012Date of Patent: September 1, 2015Assignee: Visuum, LLCInventors: John D. Cox, James Gimlett, Shaun Georges, David Cleaves

Publication number: 20140037058Abstract: An x-ray system comprises a c-arm base unit, a detector tray and a c-arm movably supported on the base to permit articulation above a patient to be examined. The c-arm has an x-ray emitter emitting x-radiation in an x-ray field, an x-ray detector detecting the x-rays and removably resting at the detector tray. An upper portion of the c-arm holds the x-ray emitter. The c-arm has a retractable lower portion with an articulating assembly removably holding the detector tray at the lower end and articulating the detector tray away from or in towards a center of the c-arm to stowed positions when attached. The c-arm slides with respect to the upper portion of the c-arm such that, when retracted, the upper portion can be placed over the patent who is resting on a surface having an obstruction therebeneath that would prevent the lower portion from accessing under the surface.Type: ApplicationFiled: August 2, 2013Publication date: February 6, 2014Applicant: Visuum, LLCInventors: John R.
