Single-shot multiple-depth macroscopic imaging by spatial frequency multiplexing.

We present a low-coherence interferometric imaging system designed for 3-dimensional (3-D) imaging of a macroscopic object through a narrow passage. Our system is equipped with a probe-type port composed of a bundle fiber for imaging and a separate multimode optical fiber for illumination. To eliminate the need for mechanical depth scanning, we employ a spatial frequency multiplexing method by installing a 2-D diffraction grating and an echelon in the reference arm.

Australian residence and heart disease risk in Vietnamese-born women.

The aim of this study was to compare the disease risk profile of Vietnamese women who have lived in Australia for 2-15 years with a newly arrived group of Vietnamese women. The design was a comparison of two cross-sectional surveys (n = 256); one newly arrived (n = 159) and one (n = 97) who had lived in Australia for 2-15 years. The main outcome measures were body mass index (BMI), waist to hip ratio (WHR), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and TC/HDL ratio (atherogenic index).

A Cartesian coordinate system for human cerebral cortex.

The most commonly used method for specifying the locations of functional areas in the human cerebral cortex is the coordinate system of Talairach and Tournoux (Co-planar Stereotaxic Altas of The Human Brain (1988) Georg Thieme Verlag, Stuttgart). It was designed to locate subcortical nuclei by reference to an axis joining the anterior and posterior commissures. The coordinate system has difficulties, however, when applied to cortical locations: (1) it can be difficult to locate the posterior commissure (PC); (2) the fundamental axis is short, and errors in specifying the axis lead to large errors at the cortical surface; (3) there is no normalisation for brain size.
