Phase-contrast computed tomography (PCCT) is an X-ray-based imaging method measuring differences in the refractive index during tissue passage. While conventional X-ray techniques rely on the absorption of radiation due to differing tissue-specific attenuation coefficients. PCCT enables the determination of the electron density (ED). By the analysis of respective phantoms and ex vivo ... https://www.roneverhart.com/Ranch-Style-Beans-Ornament/
