摘要： A magnetic field measuring method in a magnetic resonance imaging (MRI) apparatus includes applying a radio frequency (RF) pulse to an object, acquiring first and second echo signals from a first readout gradient according to test gradients having different intensities, acquiring third and fourth echo signals from a second readout gradient according to the test gradients having different intensities, and determining a characteristic value of an eddy field based on an echo time (TE) of at least one of the first through the fourth echo signals.

摘要： A method of diagnosing a magnetic resonance imaging (MRI) system includes forming a gradient magnetic field in a scanning space where a target object is positioned by generating a plurality of modified gradient pulses based on a reference gradient pulse and applying one of the plurality of modified gradient pulses to one of an x-axis coil, a y-axis coil, and a z-axis coil included in a gradient coil, applying a radio frequency (RF) pulse from an RF coil to the target object in the scanning space where the gradient magnetic field corresponding to each of the plurality of modified gradient pulses is formed, receiving a plurality of RF signals that are generated from the target object and correspond to the plurality of modified gradient pulses, and compensating an output of the gradient coil based on the plurality of received RF signals.

摘要： The MRI apparatus includes a processor configured to apply a gradient echo pulse sequence that makes a sum of gradients applied during one repetition time (TR) in a slice selection direction, a phase encoding direction, and a frequency encoding direction equal zero and maintains spins in an object in a steady state; alternately apply, while the gradient echo pulse sequence is continuously applied, a first radio frequency (RF) pulse having a first flip angle and a second RF pulse having a second flip angle that is different from the first flip angle at each TR interval; and generate an MR image based on an echo signal acquired when the spins are in the steady state.

摘要： A magnetic resonance imaging apparatus includes a signal transceiver, and a sequence controller configured to control the signal transceiver to apply an RF pulse and a gradient magnetic field to a first portion of an object, wait for blood to flow from the first portion of the object to which the RF pulse and the gradient magnetic field are applied, to a second portion of the object, and apply the RF pulse and the gradient magnetic field to the second portion of the object to which the blood flows, using a 3D balanced steady-state free precession (bSSFP), and subsample first magnetic resonance data from the second portion of the object to which the RF pulse and the gradient magnetic field are applied. The apparatus further includes an image processor configured to generate label image data based on the first magnetic resonance data.

摘要： A display apparatus and a method of controlling a screen thereof are provided. The method includes displaying a rectangular screen including a digital image in a display area, receiving information to modify a shape of the rectangular screen, and modifying and displaying the shape of the rectangular screen based on a coordinate value of a horizontal axis of the display area, and the received information. A height of the modified screen decreases as the height is closer to the coordinate value, and the digital image decreases in size as the digital image is closer to the coordinate value to correspond to the height.
