Method and apparatus for generating a panoramic image by combining image data generated from multiple perspectives
An apparatus for generating a panoramic image of part of a target, the apparatus including a source of penetrating radiation and a detector aligned with the source of penetrating radiation. The detector and source of penetrating radiation are rotate-able together with respect to the target. The detector has an array of radiation sensors arranged in rows and columns and is configured to output contents of each radiation sensor in the array of radiation sensors. The apparatus also includes a computer connected to the detector and configured to generate a panoramic image by combining data from sensors in the same row in different columns in different readout intervals, corresponding to different positions of the detector as it rotates with respect to the target. The combined outputs are selected to represent rays of radiation passing through a point on a defined curve. The computer is further configured to alter the defined curve and generate a second panoramic image using the altered curve and combing data from the sensor a second time.
