[2D13] Dynamic Range Estimation of a Low-noise Current Sensitive Preamplifier VIEC

*Ikuo Kanno1, Junichiro Nishikawa1, Hideaki Onabe2 (1. Kyoto Univ., 2. Raytech Corp.)

Keywords:X-ray, Current sensitive preamplifier, Computed tomography, Low-noise

We measured dynamic ranges of low-noise current sensitive preamplifier VIEC without and with an auxiliary circuit and of conventional current preamplifier IPA-6. Computed tomography measurement was performed using the VIEC with the auxiliary circuit for a strongly attenuating phantom.
