20080204019 | HIGH FIELD MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD FOR OBTAINING HIGH SIGNAL-TO-NOISE BY ITS RECEIVING COIL - In a high field magnetic resonance imaging apparatus and a method for obtaining signals having a high signal-to-noise ratio with the receiving coil thereof, the apparatus has at least a basic magnet and a receiving coil, the basic magnet generating a basic magnetic field, and the receiving coil being disposed within the basic magnetic field and forming an accommodating cavity. The accommodating cavity of the receiving coil is perpendicular to the direction of the basic magnetic field and is positioned in the field of view of the apparatus. The receiving coil is a loop type coil. The apparatus can further have a bracket for fixing the receiving coil. In the method, a receiving coil is used to receive signals in a magnetic field, wherein the receiving coil is perpendicular to the direction of the magnetic field. By using the apparatus and the corresponding method since the receiving coil can have a loop type design, the signal-to-noise ratio is increased. Moreover, the receiving coil can be disposed at a position closer to the center of the field of view, so that the imaging quality is improved. | 08-28-2008 |
20080238426 | METHOD AND APPARATUS FOR REDUCING ALIASING ARTIFACTS IN THE IMAGING FOR MR-MONITORED HIFU THERAPY - In a method and magnetic resonance (MR apparatus for reducing aliasing artifacts in the imaging for MR-monitored high intensity focused ultrasound HIFU therapy, a primary coil is used to receive the MR signals, and an additional coil is provided to receive interfering MR signals that form aliasing artifacts in the MR-monitored HIFU therapy imaging. The MR signals received by the primary coil and the interfering MR signals received by the additional coil are concurrently acquired. The interfering MR signals received by the additional coil are removed from the MR signals received by the primary coil. MR images are generated based on the MR signals with the interfering MR signals removed. Aliasing artifacts caused by the interfering MR signals thus are removed from the MR images without reducing the resolution of the scanned body parts in the MR images. In addition, the MR scanning time can be maintained by using a proper phase oversampling technology in the concurrent signal acquisition. | 10-02-2008 |
20090115418 | MAGNETIC RESONANCE COIL COMPOSED OF RELATIVELY MOVABLE CONSTITUENT ELEMENTS - A magnetic resonance coil has an antenna portion for accommodating a body part to be examined, the antenna portion is formed by a number of constituent units connected in series, the positions between various constituent units are relatively movable.

By increasing or reducing the number of the constituent units, or by adjusting the overlapped area between the constituent units, one pair or a number of pairs of the constituent units are made to overlap completely, so as to achieve the adjustment of the size of the antenna portion to accommodate a body part to be examined, and to make said antenna portion as close as possible to the body part to be examined, so as to obtain a signal with a relatively high signal-to-noise ratio, and to obtain a relatively high imaging quality. | 05-07-2009 |
20090174498 | RF SWITCH DEVICE, MAGNETIC RESONANCE IMAGING SYSTEM AND AN RF SIGNAL TRANSMISSION METHOD - A radio frequency (RF) switch device has at least two RF switch units, each RF switch unit having an output terminal and at least two input terminals. The RF switch units select one channel of RF signals from several channels of the RF signals that are supplied as inputs to their input terminals for emission as an output from their output terminals. A magnetic resonance imaging system and an RF signal transmission method employ such an RF switch device. The use of such an RF switch device reduces the number of channels of the RF signals that need to be further transmitted, which in turn reduces the number of the corresponding long RF cable channels and the number of channels of the subsequent devices, thereby preventing waste and reducing the cost of the system. Moreover, if the subsequent devices include a receiver coil channel selector, then the complexity of the receiver coil channel selector will also be reduced as the number of RF signal channels is decreased. | 07-09-2009 |
