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 |

20090140735 | TEMPERATURE-CONTROLLED MAGNETIC RESONANCE IMAGING METHOD AND APPARATUS - A method for improving the imaging quality of magnetic resonance imaging (MRI) equipment and MRI equipment, include obtaining a corresponding relationship between a deterioration factor of imaging quality and the cumulative energy of gradient pulses applied by successive scanning MRI sequences, then determining a predicted value of a current deterioration factor of imaging quality according to the currently applied cumulative energy of the gradient pulses and said corresponding relationship, adopting a corresponding method to carry out dynamic regulation or compensation using the predicted value of said deterioration factor of imaging quality as a reference, so as to cancel the influence produced by the heating effect of the gradient system to the imaging quality, thereby effectively improving the imaging quality of the MRI equipment. | 06-04-2009 |
20090171189 | MAGNETIC RESONANCE COIL FIXED IN PLACE BY AIR PRESSURE - An air pressure fixed coil for magnetic resonance imaging has a surface on which an air pressure fixing device is arranged. The air pressure fixing device is in communication with a control switch, that is operable to actuate the air pressure fixing device to generate a negative pressure or to restore a normal air pressure, so that the air pressure fixing device is suctioned and fixed onto an object, or is released from the object. Since the coil is fixed in place by using air pressure, the coil can be fixed onto a patient bed without arranging any fixing structure on the patient bed, and therefore the coil can be positioned and fixed at any place on the patient bed for carrying out a scanning operation according to needs. At the same time, since there is no need to pre-arrange any fixing structure on the patient bed, such as slots, holes etc., the structural strength of the patient bed will not be affected, and the appearance of the patient bed can be kept simple, clean and neat. | 07-02-2009 |
