  • Patent number: 9541615
    Abstract: A system and method for producing an image using a radio frequency (RF) coil in a magnetic resonance imaging system (MRI). A static magnetic field (B0) extends across a first and second region of interest (ROI). A local radio frequency (RF) coil, shaped like a dental arch, is positioned proximate to the ROIs, the ROIs being the upper and lower jaw of a subject. The RF coil and the subject are oriented in the static magnetic field (B0) to align an axis extending through a loop of the coil with the B0 direction of the static magnetic field extending across the ROIs. A pulse sequence is then performed with the MRI system and the RF coil to acquire imaging data from the ROIs simultaneously while using a transverse component of an excitation field (B1). The image data is reconstructed to create an image of the ROIs.

While pressing the distal end against the wall, position measurements are accepted from the probe indicating a position of the probe within the body cavity, and force measurements are accepted from the probe indicating a force between the distal end and the wall. A distortion in the simulated surface is created at the position indicated by the position measurements, so as to form a distorted surface, upon detecting that the force measurements exceed a predefined amount. The distorted surface is then displayed.

  • Patent number: 8487615
    Abstract: The receive coil arrangement includes an inner local volume coil adjacent the part to be imaged so as to maximize the received MR signal and an outer coil, which may be the built in body coil of the magnet, connected by cable to the signal processing system. Both the coils are individually tuned to the common resonant frequency and the local volume coil include an arrangement to halt current flow therein during the transmit stage. The local volume coil has no cable and is arranged to communicate the MR signal therein to the signal processing system through the outer coil by inductive coupling to the outer coil. Despite inherent losses by interfering with the tuning of the loops and in the inductive coupling this magnifies the MR signal and makes the local volume coil wireless.

  • Patent number: 8473027
    Abstract: A draping provides at least partial and preferably complete coverage of MRI coils, an MRI table and an MRI support system thereby protecting a patient and the equipment. Draping notch fold down flaps may be pushed into shaped apertures of an MRI apparatus by the patient's breast due to the design of the draping. This offers a barrier between the patient and the equipment pad providing the patient with warmth, comfort and protection from infectious diseases such as Methicillin-resistant staphylococcus aureus (MRSA). The draping reduces the clean up and improves the procedure turnaround time for the technologist.

  • Publication number: 20130137969
    Abstract: An MRI antenna array including a housing and a substrate, antenna elements and circuitry encapsulated by the housing. The housing, antenna elements, and substrate are flexible to allow the housing to distort in three dimensions to closely conform to contours of a patient. The antenna elements are mounted to the substrate in a manner that permits each element to maintain a desired resonance when the housing is distorted in three dimensions. The circuitry is electrically coupled with the antenna elements to maintain tuning and isolation of the elements when the housing is distorted in three dimensions. The housing, antenna elements, and substrate may be elastic to allow the housing to be worn by a plurality of different sized patients so that the housing is in close contact with the patient and conforms to contours of the patient.

  • Patent number: 8412310
    Abstract: A locking syringe with an integrated bias member, for delivering medical fluids at high pressure, can include a housing, a shaft, a piston, a cap assembly, a bias member, and a locking member. A distal end of the housing can interface with a patient delivery apparatus. A piston can be connected to the distal end of the shaft and can include a peripheral sealing surface that can slidably engage the inside surface of the housing to form a movable seal. The cap assembly at the proximal end of the housing can engage the shaft. A base cap can secure the piston within the housing. The bias member can have a distal end coupled to the piston and a proximal end restrained, such as to help pressurize the internal cavity. The user-actuatable locking member can user-selectively engage and inhibit unwanted movement of the shaft.

  • Patent number: 8344728
    Abstract: NMR spectroscopy is performed on intervertebral disc tissue. Extent of degeneration is determined based on the NMR spectroscopy. Correlation between NMR spectral regions and at least one of tissue degeneration and pain are made. Accordingly, NMR spectroscopy is used to determine location and/or extent of at least one of degeneration or pain associated with a region of tissue, such as for example in particular disc degeneration, or discogenic pain. NMR spectral peak ratios, such as between N-Acetyl/cho and cho/carb, are readily acquired and analyzed to predict degree of tissue degeneration and/or pain for: tissue samples using HR-MAS spectroscopy; and larger portions of anatomy such as joint segments such as a spine, using clinical 3 T MRI systems with surface head or knee coils; and tissue regions such as discs within spines of living patients using 3 T MRI systems with a surface spine coil, thus providing a completely non-invasive diagnostic toolset and method to image and localize degeneration and/or pain.
