Abstract
The present invention discloses a multi-resolution detector for use in an x-ray imaging implementation such as computed tomography and digital radiography. The multi-resolution detector includes a two-dimensional, m.times.n element array of low resolution detector elements and at least one high resolution detector element located about the two-dimensional, m.times.n element array of low resolution detector elements. After an object has been completely scanned with the multi-resolution detector the scan data from both the two-dimensional, m.times.n element array of low resolution detector elements and the high resolution detector element is used to reconstruct a high resolution image. In particular, the scan data generated from the two-dimensional, m.times.n element array of low resolution detector elements is used along with the initial scan data generated from the high resolution detector element to iteratively construct a high resolution image of the object.
