Patent ID: 7995705

Claim:
A method of inspecting an object, having a height, and generating an image representation of said object, comprising: Establishing an inspection region defined by a radiation source and a detector array having a plurality of detectors; Calibrating the plurality of detectors by deriving a baseline radiation measurement, wherein said baseline radiation measurement is taken before said object enters the inspection region; Establishing a first horizontal position; Setting values of said plurality of detectors to zero; Irradiating said object within said inspection region; Obtaining measurements of transmitted radiation from said plurality of detectors; Determining if all of said detectors in the detector array have been queried for measurements of transmitted radiation taken at the first horizontal position; and If all of said detectors in the detector array have been queried for measurements of transmitted radiation taken at the first horizontal position, establishing a second horizontal position and setting the values of said plurality of detectors to zero.
