1. imaging system comprises:

  • Radiation source (112), its around the longitudinal axis in the inspection area around rotation and the formula of leaping scan period in emitted radiation in the direction translation of the described longitudinal axis, leap in the formula scanning described, described radiation source (112) is the described direction physical translation along the described longitudinal axis in described scan period;

    Source collimator (114), it passes the radiant flux of the general conical of described inspection area in the described formula scan period collimation institute radiation emitted that leaps with formation, wherein, described source collimator (114) dynamically changes collimation in described scan period, so that increase and reduce the width of described radiant flux on described y direction in described scan period;

    Detector array (122), its detection pass the radiation of described inspection area and generate this radiating signal of indication;

    AndReconstructor (126), it rebuilds described signal to generate the volumetric image data of the described inspection area of indication.
