Claim:
An X-ray security inspection machine, comprising: a machine housing defining an X-ray tunnel for receiving an article to be inspected; a conveyor for conveying the article through the tunnel; an X-ray source for irradiating the article within the tunnel, wherein said X-ray source and conveyor define an imaging region having a volume; a photodetector array module for detecting X-rays transmitted through the article, wherein said photodetector array module has a first stowed configuration in which the photodetector array module decreases the volume of the imaging region and a second deployed configuration in which the photodetector array module projects from the machine housing and leaves the imaging region substantially unobstructed and wherein in said first stowed configuration the machine is not operational and in said second deployed configuration the machine is operational; and an actuator moving the photodetector array module between the stowed and deployed configurations.
