Radiation dose associated with common computed tomography examinations and the associated lifetime attributable risk of cancer.

open access: yesArchives of Internal Medicine, 2009
BACKGROUND Use of computed tomography (CT) for diagnostic evaluation has increased dramatically over the past 2 decades. Even though CT is associated with substantially higher radiation exposure than conventional radiography, typical doses are not known.

High-resolution computed tomography reconstructions of invertebrate burrow systems [PDF]

open access: yes, 2015
The architecture of biogenic structures can be highly influential in determining species contributions to major soil and sediment processes, but detailed 3-D characterisations are rare and descriptors of form and complexity are lacking.

Fast Image Segmentation Using Two-Dimensional Otsu Based on Estimation of Distribution Algorithm

open access: yesJournal of Electrical and Computer Engineering, 2017
Traditional two-dimensional Otsu algorithm has several drawbacks; that is, the sum of probabilities of target and background is approximate to 1 inaccurately, the details of neighborhood image are not obvious, and the computational cost is high. In order
