Claim:
1. A CT device based on straight trajectory comprising: a ray generator configured to generate a ray beam within a specific range of field angle, a first collimator configured to restrain the ray beam; a channel having a longitudinal axis, and configured to accept an object to be inspected to pass through; and a ray receiver configured to receive the ray beam restrained by the first collimator; wherein: the ray receiver is configured to transmit data from a received ray beam to an imaging computer to process and display the data, the ray generator is stationary, and the first collimator and the ray receiver are movable, a first track and a second track parallel to each other provided on both sides of the channel, wherein the first track and the second track are straight tracks parallel to the channel, and the first collimator and the ray receiver are configured to move in a same direction parallel to the longitudinal axis of the channel along the first track and second track, respectively, such that the ray beam generated by the ray generator is received by the ray receiver after penetrating the first collimator and the object to be inspected at any position within the channel in order.
