Abstract
A method and apparatus for determining a specified physical characteristic in an object exposes the object to at least two angularly fixed sources of electromagnetic radiation to create projected images of the object. The sources are rotationally scanned about the object so as to oscillate in an angular range about the object. The sources are relatively stationary to one another. A three dimensional reconstructed image of the object based on the projected images of the object is created and examined for a specified physical characteristic in the object.
