Patent number: 9063238Abstract: In accordance with one embodiment, a digital X-ray detector is provided. The detector includes a scintillator layer configured to absorb radiation emitted from a radiation source and to emit optical photons in response to the absorbed radiation. The detector also includes a complementary metal-oxide-semiconductor (CMOS) light imager that is configured to absorb the optical photons emitted by the scintillator layer. The CMOS light imager includes a first surface and a second surface, and the first surface is disposed opposite the second surface. The scintillator layer contacts the first surface of the CMOS light imager.Type: GrantFiled: August 8, 2012Date of Patent: June 23, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: James Zhengshe Liu, David Ellis Barker

Patent number: 9025730Abstract: Systems and methods for braking and releasing one or more pivot joints used in an X-ray positioning device are described. The systems and methods use a support arm that extends between a main assembly of the x-ray positioning device and an X-ray imaging assembly with an X-ray source and an X-ray detector that are disposed nearly opposite to each other. The support arm includes one or more pivot joints (such as horizontal, lateral, and/or orbital pivot joints) that allow the imaging assembly to move with respect to the main assembly. The pivot joints can each be connected to an automated braking system that is capable of selectively locking and unlocking a corresponding pivot joint, as indicated by a user-controlled switching mechanism. The braking systems containing multiple pivot joints can be individually controlled by separate switching mechanisms or simultaneously controlled by a single switching mechanism. Other embodiments are described.Type: GrantFiled: October 30, 2014Date of Patent: May 5, 2015Assignee: General Electric CompanyInventors: David Ellis Barker, John Matthew Simmons

Publication number: 20150103973Abstract: An x-ray system with multiple dynamic range selections. The system including an x-ray source and a detector, wherein the detector includes a scintillator and a pixel. The pixel includes a photodiode and first and second capacitors connectable to the photodiode. The pixel is configured to be switched between a first state where only the first capacitor is connected to the photodiode and a second state where both capacitors are connected to the photodiode. The x-ray source directs x-rays to the detector and a region of interest positioned between the source and detector, the scintillator converts the x-rays to light, and the pixel photodiode converts the light to an electrical charge. The charge is stored in the first capacitor when the pixel is in the first state and in the first and second capacitors when the pixel is in the second state.Type: ApplicationFiled: October 11, 2013Publication date: April 16, 2015Applicant: General Electric CompanyInventors: James Zhengshe Liu, Jonathan Edvard Snyder, Richard Larry Anderton, David Ellis Barker, Brian James Grekowicz

Publication number: 20150071412Abstract: C-arm retention locks allowing users to secure and unsecure C-arm positioning devices of an X-ray machine, systems containing such locks, and methods of using such locks are described. The C-arm retention lock comprises a latch bail and a latching assembly. The latching assembly comprises a latch base having an ear and a generally flat engagement surface at an end of the latch base proximate the ear, a latch having an arm, the latch being pivotally connected to the latch base so the latch is rotatable between closed and open positions, and a tensioning device engaging the latch and latch base such that the tensioning device pulls the latch toward either of the closed or open positions. The latching assembly or latch bail is configured to be connected to a C-arm and the latching assembly retains the latch bail between the ear and the arm when the latch is closed.Type: ApplicationFiled: September 6, 2013Publication date: March 12, 2015Applicant: General Electric CompanyInventors: John Matthew Simmons, David Ellis Barker, Krishnanand Prabhu Bailur, Allen Michael Collins
