A study to improve the image quality in low-dose computed tomography (SPECT) using filtration

BACKGROUND: The output of the X-ray tube used in computed tomography (CT) provides a spectrum of photon energies. Low-energy photons are preferentially absorbed in tissue; the beam spectrum shifts toward the higher energy end as it passes through more tissue, thereby changing its effective attenuati...
