Abstract
Although Xβray microscopic computed tomography is widely used to assess the structural properties of polymeric tissue scaffolds its validity is dependent on the quality of the images obtained. Here, the role of resolution, integration time, image averaging, and Xβray power on the accurate determination of scaffold porosity, while aiming to minimize imaging time, was investigated. This work identified key parameters for optimization and a methodology to vary them to improve results. Based on this, guidelines were developed to assist in the selection of image acquisition parameters to allow rapid and accurate scaffold imaging as required for mass manufacture.

This paper introduces a newly conceived formalism for clinical in-line phase-contrast X-ray imaging. The new formalism applies not only to ideal ''thin'' objects analyzed in previous studies, but also applies to the real-world tissues used in actual clinical practice. Moreover we have identified the
## Abstract Computer tomography has been used frequently for the 3βD visualization of plant anatomical traits but sample preparation has been widely neglected. Without any preparation smaller (i.e., up to 1 Γ 1 cm^2^) turgescent or semiβdry plant samples (especially leaf samples) diminish the image
