Visualizing plant development and gene expression in three dimensions using optical projection tomography.

A deeper understanding of the mechanisms that underlie plant growth and development requires quantitative data on three-dimensional (3D) morphology and gene activity at a variety of stages and scales. To address this, we have explored the use of optical projection tomography (OPT) as a method for capturing 3D data from plant specimens. We show that OPT can be conveniently applied to a wide variety of plant material at a range of scales, including seedlings, leaves, flowers, roots, seeds, embryos, and meristems.

A volumetric approach to glandularity estimation in mammography: a feasibility study.

In mammography, the reliable estimation of the volume of glandular tissue can lead to improvements in mean glandular dose calculations and mammographic risk assessment. Using the h(int) model, this paper presents a novel approach to the volumetric estimation of glandular tissue. The paper reports investigations into the effects of a range of parameters involved in the model.
