Patent number: 8848867Abstract: The present invention pertains to an apparatus and method for adaptive exposure in imaging systems. An x-ray source for producing x-ray radiation and an x-ray detector for measuring amount of x-ray radiation passing through the human patient and striking the detector can be used. A tomographic image of the human patient or a tomosynthetic image of the human patient can be generated. Region of interest filtering and equalization filtering can be utilized. Filtering can be accomplished with a mechanical shield or shutter or with electronic control of the x-ray source.Type: GrantFiled: November 23, 2011Date of Patent: September 30, 2014Assignee: Triple Ring Technologies, Inc.Inventors: Tobias Funk, Steve Denis Burion, Kate Leeann Bechtel, Joseph Anthony Heanue, Brian Patrick Wilfley, Augustus Percival Lowell

Publication number: 20140254748Abstract: The present invention pertains to a system and method for X-ray imaging wherein a targeted fluence at the detector for projection images can be achieved at a plurality of projection angles around the imaging subject by control of exposure times implemented during image acquisition. Exposure time for a second projection image may be determined by the fluence in a first projection image, and in a third projection image by the fluence in a second projection image, where projection images are acquired within two degrees of one another. An acquisition parameter calculation can be configured to calculate acquisition parameters, such as said exposure times, to achieve the targeted fluence in projection images and can be coupled to a rotation controller that implements the acquisition parameters by controlling a relative angle between the imaging subject and X-ray image acquisition device.Type: ApplicationFiled: May 16, 2013Publication date: September 11, 2014Applicant: TRIPLE RING TECHNOLOGIES, INC.Inventor: TOBIAS FUNK

Publication number: 20140205067Abstract: A device is used to precisely deliver the treatment plan created by an automatic planning system by positioning a single low energy radiation source, or a plurality of low energy sources connected to each other, in a predetermined parallel, planar, or similar geometry, each source equipped with blocking and attenuation mechanisms, thereby delivering a plurality of parallel overlapping beams indexed on a millimeter or submillimeter grid such that a concentration of dose is achieved at a variable depth in tissue relative to the dose where the radiation first enters the tissue. A plurality of overlapping beams indexed on a millimeter or submillimeter grid can converge on a target volume loaded with gold nanoparticles to deliver a tumorcidal dose of radiation in as little as a single session to tumor cells but not to normal cells or to deliver serial radiosurgical treatments.Type: ApplicationFiled: January 31, 2014Publication date: July 24, 2014Applicant: TRIPLE RING TECHNOLOGIES, INC.Inventors: Mark Philip Carol, Joseph Anthony Heanue

Patent number: 8774351Abstract: The present invention pertains to an apparatus and method for X-ray imaging a human patient. A vacuum bell bonded to an X-ray radiation-permeable window that can emit X-ray radiation from a plurality of spots located 1 cm from its edge, a collimator, and a detector are used. A ring of stationary X-ray sources can also be used with a stationary collimator and a rotating slot collimator and detector. An X-ray beam can be aligned in an X-ray system by establishing a position of the beam with respect to a moving collimator at a number of points in time, monitoring the velocity of the collimator, navigating the beam to a calculated position of a hole in the collimator, and correcting the alignment of the beam based on the location of the beam on the detector.Type: GrantFiled: April 5, 2012Date of Patent: July 8, 2014Assignee: Triple Ring Technologies, Inc.Inventor: Tobias Funk

Publication number: 20140177785Abstract: The present invention pertains to an apparatus and method for medical imaging comprising rotating two X-ray source-detector pairs around an axis of rotation simultaneously to quickly acquire image data and form a computed tomography (CT) dataset. The sources can be configured to emit radiation from a plurality of discrete locations. The CT dataset can be utilized as a prior to reconstruct a three-dimensional image from subsequent bi-planar imaging with these source-detector pairs.Type: ApplicationFiled: December 20, 2012Publication date: June 26, 2014Applicant: Triple Ring Technologies, Inc.Inventor: TOBIAS FUNK
