X-RAY TECHNIQUE-BASED NONINTRUSIVE INSPECTION APPARATUS HAVING AN ADJUSTABLE COLLIMATOR ASSEMBLY |
摘要 |
An x-ray-based nonintrusive inspection apparatus has a collimator shield. An adjusting actuator is actuable to move the collimator shield between a pre-scanning position and a CT scanning position, in the pre-scanning position, the collimator shield exposing a smaller portion of a respective crystal to the x-rays than in the CT scanning position. A controller is connected to a gantry motor and the adjusting actuator. The controller controls the motor and the adjusting actuator such that the collimator shield is in the pre-scanning position when a gantry is stationary and in the CT scanning position when the gantry is rotating.
