 note = {We have attempted to calculate a primary X-ray spectrum of CT (Computed Tomography) system. Dose rates of primary X-ray spectrum are very high, so we reduced dose rate by using carbon scatterer and enabled to measure 90°-scattered spectrum with a CdZnTe detector. The primary X-ray spectrum can be calculated from measured data of 90°-scattered spectrum by counting backwards. In counting backwards, we used not only Klein-Nishina co-efficients but also response functions obtained by Monte Carlo methods, because Raylei scattering and multiple scattering maybe occur in carbon scatterer.
 In our results, the primary X-ray spectrum calculated from response functions obtained by Monte Carlo methods are roughly equivalent to that calculated from Klein-Nishina coefficients.},
