1. A method for reducing the effect of object movements along MRI imaging;

  • the method comprising steps of;

    a. acquiring a sequence of N MRI consecutive images CIn of an object;

    b. storing on a computer readable medium (CRM) for each of said CIn;

    at least one parameter p indicating spatial image orientation at which said image was taken;

    c. analyzing said sequence of said CIn for detection of said object movement; and

    tagging thereby KM images CIkM of at least one movement M of said object;

    d. for each of said movement M, determining the following using said tagged images CIkM;

    a. two of the following;

    the movement starting time TMS, the movement ending time TME, and time length of said movement TM;

    b. the movement spatial image orientation parameter PMS at the beginning of the movement,wherein said method additionally comprising for each said M, whose TM is shorter from a predetermined time length PT, steps ofe. acquiring a sequence of KM MRI consecutive images NCIkM starting at said PMS; and

    ending after said TM;

    f. replacing said NCIkM with said CIkM in said sequence;

    g. repeating steps (c)-(f) until no more movements whose TM is shorter than said PT can be detected;

    thereby, producing an image sequence with reduced object-movement in MRI imaging.
