Patent number: 8465203Abstract: Systems and methods for using a brake system to selectively lock and release the vertical motion of a C-arm X-ray device that is part of a sliding counterbalanced C-arm positioning device are described. In such systems and methods, the C-arm positioning device typically includes a C-arm X-ray device, a linear bearing rail assembly, a linear bearing block, a counterbalance mechanism, and brake system. Generally, the C-arm is connected to the linear bearing block, which is slidably coupled to the bearing rail assembly to allow the bearing block and C-arm to slide up and down on the rail assembly. The counterbalance mechanism applies a force to the bearing block to substantially counterbalance the weight of the components, such as the C-arm, that are suspended from the bearing block. The brake system can be actuated to engage the linear bearing rail assembly and lock the vertical movement of the linear bearing block. Other embodiments are described.Type: GrantFiled: March 2, 2011Date of Patent: June 18, 2013Assignee: General Electric CompanyInventors: David Barker, John Matthew Simmons, Jan Bruening

Patent number: 8459867Abstract: The invention relates to an X-ray apparatus and a medical workstation. The X-ray apparatus has a first robot (R1) and a second robot (R2). The first robot (R1) has a plurality of first axles, a first securing device and a first control device (17) designed to actuate the first axles of the first robot (R1) for a movement of the first securing device. The second robot (R2) has a plurality of second axles, a second securing device and a second control device (37) designed to actuate the second axles of the second robot (R2) for a movement of the second securing device. An X-ray source (RQ) is arranged on one of the two securing devices, and an X-ray receiver (RE) is arranged on the other securing device.Type: GrantFiled: March 30, 2009Date of Patent: June 11, 2013Assignee: KUKA Laboratories GmbHInventor: Michael Muller

Patent number: 8454233Abstract: A device for non-destructive testing of objects, particularly pipes in oil refineries, having a first positioning device for positioning a collimator including a radioactive radiation source near an object to be tested, and a second positioning device for positioning a film carrier near the object to be tested. The first positioning device may be anchored or placed with a lower end on a substantially flat base surface, wherein the collimator is attached to the opposite, upper end of the first positioning device. Before the exposure, the radiation source may be guided towards the collimator via a delivery tube such that no radiation is able to be emitted from the device during the placement of the first positioning device.Type: GrantFiled: April 8, 2008Date of Patent: June 4, 2013Inventor: David Robb Cochrane

Patent number: 8430564Abstract: Systems and methods for making and using sliding counterbalanced C-arm positioning devices are described. In such systems and methods, each C-arm positioning device includes a C-arm X-ray device, a linear bearing rail, a linear bearing block, and a counterbalance mechanism. Generally, the C-arm is connected to the linear bearing block, which, in turn, is slidably coupled to the bearing rail to allow the bearing block and C-arm to slide up and down on the rail. The counterbalance mechanism can apply a force to the bearing block to counterbalance the weight of the C-arm and the bearing block. Thus, the described C-arm positioning device can allow a user to easily raise or lower the C-arm with relatively little effort. While some implementations of the C-arm positioning device are connected to mobile support structure, other implementations of the C-arm positioning device are mounted to a fixed support structure. Other implementations are also described.Type: GrantFiled: February 28, 2011Date of Patent: April 30, 2013Assignee: General Electric CompanyInventors: John Matthew Simmons, David Barker, Jan Bruening
