abstract:

A very simple and inexpensive CT-scanner has been designed and constructed, which is able to carry out contemporaneously transmission, Compton, Rayleigh and fluorescence radiation tomography. Four detectors are located around the object to be scanned: a NaI one at 180° with respect to the incident radiation for transmission tomography; a second NaI at 90° for Compton tomography; a third NaI at 5-10° for Rayleigh tomography, and a Si-PIN or CdZnTe at 90° for fluorescent radiation tomography. Special special algorithms were employed, which include autoabsorption correction terms for Compton, Rayleigh and fluorescence tomography.
