摘要： The present disclosure discloses a radiation inspection system and a radiation inspection method. The radiation inspection system comprises a radiation source and a beam modulating device. The beam modulating device comprises a first collimating structure disposed at a beam exit side of the radiation source and a second collimating structure disposed at a beam exit side of the first collimating structure. The second collimating structure is movable relative to the first collimating structure to change a relative position of the first collimating port of the first collimating structure with the second collimating port of the second collimating structure, and the beam modulating device is shifted between a first operational state in which the beam modulating device modulates an initial beam into a fan beam, and a second operational state in which the beam modulating device modulates the initial beam into a pencil beam variable in position.

摘要： A straight trajectory CT device can be used in radiation imaging. The device includes: a ray-generating unit that generates a ray within a specific range of field angle; a channel for an object to be inspected though which the object to be inspected passes; a first collimator; and a ray receiving unit provided on both sides of the channel for the object to be inspected. The ray beam is received by the ray receiving unit after penetrating the first collimator and the object to be inspected in order. The ray generating unit is static and the first collimator moves in the same direction as the ray receiving unit. This direction is parallel to the channel for the object to be inspected. The device can complete computed tomography with a minimum of one ray receiving unit, thereby simplifying the structure of the device and reducing its cost.
