摘要： In the NMR apparatus the resonant conditions may be kept constant by adjusting the strength of the static magnetic field. The echo signal that is induced under the specific conditions is processed so as to obtain the deviation of the resonant frequency in the correction circuit. The shift of the given static magnetic field is calculated based upon the deviation of the resonant frequency. The DC energizing current for the H.sub.O power supply is varied based upon the magnetic field shift so as to maintain the NMR phenomenon at the desirable resonant conditions.

摘要： A gradient field is applied in a coronal scheme such that a slice region along the flowing direction of a blood vessel, i.e., along the body axis is set as an imaging area. Of regions adjacent to the imaging region in the body axis direction, a region including a blood vessel as a target of imaging (in this case, an artery) through which the blood flows toward the imaging region is not excited, but only the imaging region is selectively excited. Then, since a spin in the artery is supplied to the imaging region in a fresh state, the image of this spin is formed with a signal level higher than that of a stationary spin remaining in the imaging region. Since the presaturated blood in the artery in the imaging region is returned at its peripheral portion to flow through the vein, the spin in the vein is already saturated, its signal level is lower than that of the spin in the artery, and the image of this spin is not formed. As a result, the image of the state of the artery can be formed within a short period of time.
摘要翻译：将梯度场应用于冠状方案，使得沿着血管的流动方向（即沿着身体轴线）的切片区域被设置为成像区域。在体轴方向上与成像区域相邻的区域中，没有激励作为血液朝向摄像区域流动的成像（在这种情况下为动脉）的目标的血管的区域，仅仅是摄像区域被选择性激发。然后，由于动脉中的旋转以新鲜状态提供给成像区域，所以该旋转的图像形成为具有高于保留在成像区域中的静止旋转的信号水平的信号水平。由于成像区域的动脉中的预饱和血液在其周边部分返回，流过静脉，所以静脉中的旋转已经饱和，其信号水平低于动脉中的旋转的信号水平，这种旋转没有形成。结果，可以在短时间内形成动脉状态的图像。

摘要： A magnetic resonance diagnosing apparatus has a static magnetic field magnet, a gradient magnetic field coil, a transmitter/receiver probe, a Fourier transformer, a discriminator, a DC offset changer, and a controller. The Fourier transformer transforms a time-region magnetic resonance signal acquired by the transmitter/receiver probe to a frequency-region signal in accordance with Fourier transformation. The discriminator discriminates whether the line width of the frequency-region magnetic resonance signal is not more than a predetermined value. Based on the line width of the frequency-region magnetic resonance signal, the direct current offset changer adjusts the current to be supplied at least to the gradient magnetic field coil so as to correct the offset of the static magnetic field.
