Tilted detector microscopy in computerized tomography

摘要

The present invention relates to a method and setup for providing high resolution CT images at a low cost. The method utilizes a modified version of the standard CT setup wherein the radiation receiver (e.g., a detector(s)) is tilted with respect to an axis perpendicular to the plane of fan beam projection (e.g., when a fan shaped radiation beam is used). Moreover, to maximize the utilization of the radiation receiver and obtain the highest resolution in the final image, the radiation receiver is also shifted horizontally within the radiation beam.
