Patent Images

1. a magnetic resonance imaging system is used for carrying out image scanning on the basis of required pulse sequence, so that obtain the MR image at object to be imaged desired zone place, this system comprises:

  • One prescan actuating unit is constituted as the execution prescan, with the data of a plurality of preliminary images of obtaining this object desired zone place, carries out this prescan by the size that changes the desired parameters of pulse train in each preliminary image;

    One preliminary image forming appts is constituted as the data that obtained from the prescan behavior and produces a plurality of preliminary images;

    One display device is constituted as a plurality of preliminary images of demonstration;

    One selecting arrangement is constituted as the required preliminary image of selection from shown a plurality of preliminary image;

    AndOne setting device, the size that is constituted as the desired parameters that will provide from selected preliminary image is set to the image scanning,Wherein required parameter is the intensity that is used for the pulse of mortifier body fluid flow cavitation.
