Claim One:
1. A method for estimating scan parameters from tomographic data, the method comprising: collecting tomographic data of an object during a scan, wherein one or more parameters of the scan are not accurately known; reconstructing an image of the object, wherein the information about the object in the image useful for estimating the scan parameters pertains only to one or more edges of the object image, the edges defined as sharp spatial features inside the object; estimating the one or more scan parameters using the reconstructed image of the object; and repeating the reconstructing of the image of the object and the estimating of the one or more scan parameters two or more times to improve the estimate of the one or more scan parameters, wherein the reconstructing of the image of the object and the estimating of the one or more scan parameters are repeated until a number of edges of the object having a predetermined characteristic are below a preselected threshold.
