  • Publication number: 20190190177
    Abstract: An electrical connector has an insulative elongated housing retaining a plurality of contacts therein. The housing includes an upper wall, a lower wall and a rear wall to commonly form a receiving slot. The upper wall forms a plurality of upper passageways and the lower wall forms a plurality of lower passageways to receiving the corresponding upper contacts and lower contacts therein.

  • Patent number: 10120053
    Abstract: In a magnetic resonance imaging method and apparatus, the scanner is operated with a multi-echo sequence in order to acquire k-space data of a multi-echo magnetic resonance signal, and the k-space data are used to reconstruct a magnetic resonance image. The multi-echo magnetic resonance signal is an asymmetric multi-echo magnetic resonance signal, and the asymmetric multi-echo magnetic resonance signal includes N asymmetric echo magnetic resonance signals, wherein N is greater than or equal to 2. Asymmetric echo magnetic resonance signals can be acquired in a dual-echo steady-state sequence, so that scanning time is reduced and the degree of comfort of a subject is improved because the magnetization process reaches a steady state quickly so the magnetic resonance signal is less affected by inhomogeneities that may exist in the basic magnetic field or a gradient magnetic field, and the intensity of the magnetic resonance signal is increased.

  • Patent number: 10114096
    Abstract: In a multi-slice data acquisition method and device and a magnetic resonance imaging method and apparatus, a number NC of fractional acquisitions and a number NS of slice individual, complete data acquisition of the multi-slice data acquisition are determined. Using an iterative odd/even arranging method, a slice data acquisition order of each of the fractional acquisitions is arranged according to an ideal number of iterations. The ideal number of iterations is obtained from multiple undetermined numbers j of iterations of the iterative odd/even arranging method according to the number NS of slice data and the number NC of fractional acquisitions. This multi-slice data acquisition method optimizes the slice data acquisition order so as to significantly reduce the effect of magnetization transfer and crosstalk.

  • Publication number: 20170350953
    Abstract: In a magnetic resonance coil selection method and selection computer, a range parameter of a target region (ROI) to be detected is acquired, and a detection range parameter of each available coil is acquired. A coil having a detection range that overlaps with a range of the ROI is determined and then selected. The selected coil is then used in the operation of a magnetic resonance scanner to acquire magnetic resonance data. The SNR of the magnetic resonance scanner is thereby increased, so as to improve the imaging quality.

  • Publication number: 20170273638
    Abstract: In a method and magnetic resonance (MR) apparatus for heart diffusion imaging, when an ECG trigger signal by a computer that operates an MR scanner, the MR scanner is operated to acquire a navigator echo before a stimulated echo sequence, in order to detect diaphragm position information. When the first diaphragm position information is not located in an acquisition window, the stimulated echo sequence is not executed, and the computer waits to receive the next ECG trigger signal. The detection time of the navigator echo after the stimulated echo sequence as well as the acquisition time of the stimulated echo sequence, are thus eliminated when the first diaphragm position information does not meet requirements, so can significantly reduce scanning time, and increase the image SNR.
