  • Patent number: 10459045
    Abstract: Sterile RF coil arrangements for use in magnetic resonance imaging are provided. The sterile coil arrangements can be formed by spraying or coating a curable liquid onto an RF coil housing and allowing the liquid to cure or dry to form a continuous sterile layer on the coil housing. The thickness of the sterile layer can be between 100 and 1000 micrometers. The curable liquid can include an antimicrobial or antibacterial agent, such as silver ions or triclosan, to better maintain sterility of the coil arrangement. The curable liquid can be selected such that it adheres to the housing when cured and is also removable without leaving residue behind.

  • Patent number: 10209325
    Abstract: A configurable coil arrangement for use with MRI-guided procedures is provided that facilitates optimal imaging for both pre-procedure planning and imaging of the target sites during the procedure. The coil arrangement includes a plurality of connected coil elements. Spacers connecting the coil elements can be adjustable and/or deformable to provide one or more openings in the coil arrangement of optimal size for accessing the subject within the imaged region. Individual coil elements can also be removed to provide access openings during such procedures, or left in the array for improved pre- and post-procedure image quality. The MRI system can be configured to detect configurations of the coil arrangement and modify imaging parameters to optimize image quality.

  • Patent number: 10180469
    Abstract: A magnetic resonance imaging system and method are provided that include user control of certain functions using physical gestures, such as hand motions or the like. The gesture control aspects can include one or more cameras, and a processor configured to detect and recognize gestures corresponding to predetermined commands and to provide signals to execute the commands. A verification switch, such as a foot switch, can be included to improve safety and reliability of the gesture control aspects. This switch can be used to activate the gesture detection aspects and/or to confirm a recognized gesture command prior to its execution.

  • Publication number: 20170340354
    Abstract: A method for performing image-guided embryo transfer for in vitro fertilization includes performing a pre-operative magnetic resonance imaging (MRI) scan of a subjects pelvic region to yield a first MRI image dataset. A computer applies a segmentation routine to the first MRI image dataset to yield segment data which is then used by the computer to create an anatomical model of the subjects pelvic region. The computer determines an optimal implant location based on the anatomical model and creates a three-dimensional rendering of the optimal implant location based on the first MRI image dataset.

  • Publication number: 20170269174
    Abstract: A magnetic resonance method and system are provided for magnetic resonance (MR) image-guided insertion of an object into a biological tissue along a predetermined trajectory. The trajectory provides a path between a starting point and a target site within the tissue. Sufficiently high resolution images can be generated in real time to precisely guide the needle placement. A compressed sensing approach is used to generate the images based on minimization of a cost function, where the cost function is based on the predetermined needle path, artifact effects associated with the needle, the negligible changes in the images away from the trajectory, and the limited differences between successive images. The improved combination of spatial and temporal resolution facilitates an insertion procedure that can be continuously adjusted to accurately follow a predetermined trajectory in the tissue, without interruptions to obtain verification images.

  • Patent number: 8714431
    Abstract: A friction welding tool having a pin and a clamping device with a counter bearing, a holddown element and a spring element. The pin has a coupling section for releasable, rotationally fixed coupling to a rotating output device of a machine tool. The counter bearing is held on the pin between the pin's coupling and engagement ends in a manner that allows the counter bearing to be axially immovable on but freely rotatable about a longitudinal axis of the pin. The holddown element surrounds the pin and is arranged on a side of the counter bearing facing the engagement end. The holddown element has a bearing surface for bearing on the workpiece arrangement. The spring element is provided between the holddown element and the counter bearing and is mounted on the pin in such a way that it is elastically slidable along the longitudinal axis of the pin.

  • Patent number: 5779537
    Abstract: A deposit cupboard (1) for solvents, combustible liquids and the like, comprises shelves (2) and at least one door. The cupboard is assigned an air intake holes (20) and an exhaust device (5), and distinguishes itself through the following combination of features: a) that the shelves (2) of the cupboard (1) are perforated and/or positioned at a distance from at least one of the adjacent inner faces of the side walls of the cupboard, in order to effect a minimum resistance against the air flow; b) that the cupboard is assigned a fire extinguishing apparatus (18) having an automatic, preferably thermostat-controlled release means; and c) that the top plate (4) of the cupboard is pivotally supported and adapted--upon the occurrence of an explosion within the cupboard--to be swung limitedly up into a securing or protecting position, wherein it forms an inclinedly directed shield, protecting the personnel from the effects of the explosion.
