Abstract: 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.

Abstract: 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.

Abstract: A patient table includes a table body configured for bearing a patient, a connecting rod structure configured for supporting the table body, and a spring structure. The connecting rod structure is operable such that the table body may perform a lifting motion between a high position and a low position. Both ends of the spring structure are fixed. At least a first end of the spring structure is hinged to the connecting rod structure. The spring structure may be used for driving the lifting motion of the connecting rod structure and/or bearing the table body. The patient table may be used for nuclear magnetic resonance imaging equipment.
