Reconstructed slice thickness does notdirectly affect x-ray exposure; however, this factor does determine how many photons contribute to the final image in the filtered back-projection technique, with noise being inversely proportional to the square root of reconstructed slice thickness.
Founded in 1997, TeraRecon has developed a unique family of powerful processors dedicated to performing image processing tasks such as filtered back-projection and 3D volume rendering at unprecedented speeds.
