摘要： The invention relates to an X-ray imaging system, comprising an X-ray image intensifier tube in which the electron-optical system can be adjusted to a number of different image formats. By making the image format increase or decrease visibly on the exit screen in the event of a change of image format, annoying visual adjustment effects are avoided and a patient can be continuously observed also in the event of a change of format. Because of the gradual high-voltage variation of the power supply for the electron-optical system, associated with a visible variation of the image format, the output resistance of the power supply circuit may be high. Furthermore, due to the gradual change of the mean intensity on the exit screen of the X-ray image intensifier tube, the control behaviour of the automatic exposure control and the automatic gain control of the X-ray imaging system are influenced in a positive sense.

摘要： The method includes a critical time shift of a refocusing pulse between two (90 o ) excitation pulses which produce multiple quantum coherence signals and which are followed by a (90 o ) read pulse (using a critical timing a refocusing pulse serving the same purpose can also be applied between the second excitation pulse and the read pulse). With respect to the centre of the time path between the excitation pulses or between the excitation pulse and the read pulse the time shift is chosen to be such that given resonances do not occur positively or negatively in the spectrum whereas other resonances do occur therein (i.e. at substantially maximum strength). The MRI method can be combined with the use of spatially selective gradients in order to obtain localised spectra or images.

摘要： In an image intensifier tube comprising a photosensitive layer an insulating wall portion is coated with a layer of chromium oxide which is deposited in the form of a chromium nitrate layer which is subsequently baked at a temperature of approximately 525 o C. A thin, suitably adhesive, uniform and transparent coating layer having a comparatively high resistance value is thus achieved.

摘要： In a computer tomography device comprising an X-ray tube having an elongate anode across which a focus can be displaced, a tomosynthetic scanogram can be formed by correctly shifting the profiles measured in the various source positions with respect to one another, followed by superposition. Parts of the object which are situated in a selected layer are thus emphasized in an image, parts of the object which are situated outside the selected layer being blurred. An important additional advantage consists in that the permissible power to be applied to the X-ray source may be higher. Furthermore, a scanogram thus obtained is not necessarily disturbed by the failure of one or more detectors.

摘要： A method is proposed for the automatic correction of phase errors in NMR spectra. The phase errors are inter alia due to deficiencies of the NMR hardware, the time-shifted sampling of a magnetic resonance signal after the appearance thereof. The phase correction is performed by first determining peak locations in a modulus spectrum determined from the complex spectrum and by determining the phases in the peak locations, after which the phases in the peak locations are fitted to a predetermined polynomial by means of a least-squares optimization procedure. The coefficients of the polynomial are thus defined. Subsequently, the NMR spectrum is point-wise corrected by means of the phase polynomial determined. The proposed method can be simply implemented in a NMR device; no severe requirements are imposed as regards the signal-to-noise ratio and the resolution of the spectrum. In practical situations an NMR spectrum usually comprises many spectral lines. Therefore, the method is not susceptible to the effects of overlapping spectral lines.
摘要翻译：提出了NMR光谱相位误差自动校正的方法。相位误差尤其是由于NMR硬件的缺陷，出现之后的磁共振信号的时移采样。通过首先确定从复谱确定的模式谱中的峰值位置并通过确定峰值位置中的相位来执行相位校正，之后通过最小二乘法将峰值位置中的相位拟合到预定的多项式优化程序。因此定义多项式的系数。随后，NMR谱通过确定的相位多项式逐点校正。所提出的方法可以简单地在NMR装置中实现; 在信噪比和频谱分辨率方面没有严格的要求。在实际情况下，NMR谱通常包含许多谱线。因此，该方法不易受到重叠谱线的影响。

摘要： A method is proposed for the automatic correction of phase errors in NMR spectra. The phase errors are caused inter alia by deficiencies of the NMR hardware, by the shifted sampling of a magnetic resonance signal after the occurrence thereof. Phase correction is performed by determining first the modulus spectrum from a complex magnetic resonance spectrum, after which in the modulus spectrum there are determined, with discrimination of peaks which are below a given level, the peak parameters of the remaining peaks, such as peak amplitude, peak width at half amplitude and peak position, after which, using the peak parameters determined, a model of the complex spectrum is determined which does not contain phase errors, a phase distortion being subsequently introduced into this model until the phase of the model at the edges of the spectrum corresponds as well as possible to the phase at the edges of the complex spectrum, after which finally the complex spectrum is point-wise corrected with the phase distortion introduced. The proposed phase correction does not impose strict requirements as regards the modeling, because upto a given level variations in the modeling hardly influence the phase variation at the edge of the spectrum.
摘要翻译：提出了NMR光谱相位误差自动校正的方法。通过磁共振信号发生后的移位采样，相位误差尤其由NMR硬件的缺陷引起。通过首先从复磁共振谱中确定模数谱进行相位校正，之后在确定低于给定水平的峰的模数谱中确定剩余峰的峰值参数，例如峰值振幅峰值宽度在半幅度和峰值位置之间，之后，使用确定的峰值参数，确定不包含相位误差的复谱的模型，随后将相位失真引入该模型，直到模型的相位频谱的边缘对应于复谱边缘处的相位，之后最终通过引入的相位失真对复谱进行逐点校正。所提出的相位校正并没有对建模施加严格的要求，因为建模中给定的水平变化几乎不影响光谱边缘的相位变化。
