  • Publication number: 20200264254
    Abstract: The invention relates to an MRI apparatus and a method of MRI involving the acquisition of a first and a second MRI image with mutually different orientations between the BO magnetic field and the object to be investigated. For instance, when imaging structures such as a tendon, due to the magic angle effect, this results in a change in image contrast. According to the invention, a coregistration can be performed between the first and the second MRI image. Moreover, the orientation of a structure within the object can be determined on the basis of the different orientations and the image intensity in the first and the second MRI image. The invention further discloses an apparatus for carrying out the method and a method of shimming the BO magnetic field of the apparatus.

  • Patent number: 7532008
    Abstract: A material having magnetic permeability at r.f. frequency, for example a microstructured magnetic material has a magnetic permeability of negative value but unity magnitude over a particular r.f. frequency range. The singularity in the flux pattern has the result that magnetic resonant disturbances in a plane C,E normal to the line C,D are focussed into a plane D,F also normal to the line C,D and vice versa. This is particularly applicable to magnetic resonance apparatus, since the material can be used to transfer the r.f. magnetic flux distribution in a target region in a patient, for example at C,E to D,F where the flux may be directly measured by receive coils. Equally, transmit coils may generate flux to be focussed into the target region by the material. Magnetic resonance apparatus may be constructed which does not require gradient coils, and r.f. hypothermia may be carried out in a focussed way, minimising damage to surrounding tissue.

  • Patent number: 7170363
    Abstract: Microstructure materials which can be tuned to a particular range of r.f. frequencies to display particular magnetic permeabilities have been proposed. A typical material is made of an array of capacitive elements e.g. spirals or rolls of conducting material on a non-conducting substrate. These materials can be used as a guide which is effective for the particular band of frequencies to which it is tuned. In one example, the rolls (2a to 2c) guide magnetic flux along ducts (1, 2, 3) while rolls (4a, 5a) guide magnetic flux along ducts (4, 5). Flux can thus be guided upwardly along duct (2), along ducts (4 and 5), and down ducts (1, 3), or vice versa.

  • Patent number: 6819106
    Abstract: In magnetic resonance imaging apparatus, an array of coils (7, 8, 9, 10) is used to receive magnetic resonance signals from a desired region of a patient. Screens 11 to 13 and 14 and 15 are provided between the coils and at the ends of the array of coils to control the sensitive region A of each coil but, in accordance with the invention, the screening properties of the screens is controllable so that for example the screens may be made inoperative beneath the plane of the array of coils so that each has the field of view B, in order to vary the properties produced by the array. Other uses of screens are described.

  • Patent number: 6529004
    Abstract: A magnetic resonance imaging apparatus has a patient support (1) moveable on runners (2) along a beam (3) into a bore (4). The r.f. coil (7) is secured to the patient support so as to travel axially with the patient support when the patient enters the bore. The r.f. coil is also moveable laterally to enable off-centre as well as central regions of the patient to be imaged. The apparatus is particularly suited to continuous scan. The width of the central section of the coil (7) may also be variable in a lateral direction to accommodate patients of different size.

  • Patent number: 6441711
    Abstract: A high temperature superconductor (HTSC) 5 is magnetized between drive coils 1,2 forming poles of a magnet connected by an iron yoke 9 by relative movement of a vacuum insulated cryostat 4 containing the HTSC and the magnetizing magnet, in order to magnetize a large area of HTSC using a magnet with a small region 3 of magnetizing flux. Alternatively, the HTSC 5may be contained in an evacuated region of a cryostat containing the magnetizing magnet. An interconnecting chamber allows the HTSC to be moved between an operative region and a magnetizing region without substantial loss of vacuum.

  • Patent number: 6424154
    Abstract: The image produced by a magnetic resonance imaging apparatus using a receive coil 2 has inaccuracies due to external circumstances which affect the signal produced by the coil 2. Thus, noise spikes affect the signal, although more usually extensive shielding is provided. Also, changes of loading of the coil produced by movement of the patient vary the Q of the coil and hence the signal output. In accordance with a first aspect of the invention, a second coil 4 superimposed on the coil 2 is tuned to a frequency offset compared to the MR center frequency and is used to monitor coil loading to enable the signal from coil 2 to be corrected, and in accordance with a second aspect of the invention an additional coil 4 or 8, preferably both, is/are provided in order to detect broadband noise and enable its suppression on the output of the coil 2.
