A Novel 1st Generation Computed Tomography Scanner
A preliminary design for a first generation tomography scanner is being designed and constructed. The scanner uses Na-22 as the radiation source, with annihilation photons being counted by shielded NaI detectors. The novel design of the scanner allows a very weak radiation source to be used by taking advantage of the back-to-back 511 keV annihilation photons emitted after Na-22 B+ decay to improve the signal to noise ratio. The object being scanned will be translated and rotated systematically by computerized motor control using two motors attached to a standard rotary table.
