  • 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.

  • Publication number: 20150331073
    Abstract: A medical instrument for carrying out a percutaneous intervention in a patient is provided with a marker that is visible in an MR image. A real-time magnetic resonance image of the patient is created, so that the actual position of the marker can be identified in the real-time image. For assisting a person in the positioning of the medical instrument in an initial position suitable for the intervention, a desired position of the marker that correlates with the initial position is displayed in the real-time image. The positioning thus can be carried out relatively effortlessly and quickly.

  • Publication number: 20130076355
    Abstract: A method for acquiring medical images, including: applying, during a first period, a plurality of radio frequency (RF) pulses to an area of interest, wherein the RF pulses applied during the first period are Kaiser-Bessel pulses; applying, during a second period, a plurality of 180 degree RF preparation pulses to the area; applying, during a third period, a plurality of 180 degree RF pulses to the area to acquire a center of a k-space; applying, during a fourth period, a plurality of RF pulses to the area, wherein the RF pulses applied during the fourth period have an angle smaller than the 180 degree RF pulses applied during the third period; applying, during a fifth period, a plurality of constant RF pulses to the area to acquire outer lines of the k-space; and generating an image of the area by using a steady-state free precession echo readout.
