  • Patent number: 10548505
    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: 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: 20190008411
    Abstract: In a method and apparatus for supporting a user when positioning an accessory for a magnetic resonance examination on an examination object, the actual position of the accessory is acquired by an acquisition unit, and a target position of the accessory is determined by a detection unit. The actual position and the target position of the accessory are compared with regard to deviation of the actual position from the target position of the accessory. Output information representing any deviation that is found to exist is provided to a user via an output unit.

  • Publication number: 20180294056
    Abstract: A method for optimizing operation of at least one medical imaging apparatus, and a computer for implementing such a method, an appointment request from a patient, and at least one patient attribute, are entered into a computer, and the patient attribute is forwarded from the computer to the medical imaging apparatus. The medical imaging apparatus provides the computer with the duration of the medical imaging procedure to be conducted, as a function of the patient attribute, and forwards a designation of that duration to the computer. The computer selects an appointment dependent on the duration and the availability of the medical imaging apparatus. The selected appointment is stored by the computer.

  • Publication number: 20180218338
    Abstract: In a computer-implemented method for scheduling customer appointments in one or more service centers, wherein at least some of the customers was a mobile device having a location tracking function and a message transmission function, a central appointments scheduling system manages customer appointments, which has assigned an available time window to at least one customer. A default of a customer appointment of a first customer is recorded. The position of at least one second customer, whose available time window overlaps with the defaulted customer appointment, is detected through the use of the location tracking function of the mobile device and communication of the position to the central appointments scheduling system. The expected travel time of the second customer to the service center is calculated and, if the travel time is shorter than the time remaining up to the start time of the defaulted appointment, an offer is sent to the second customer to accept the defaulted appointment.
