Three‐dimensional imaging of upper esophageal sphincter resting pressure
Laryngoscope Investigative Otolaryngology, 2019 Objective High‐resolution manometry (HRM) is used to analyze upper esophageal sphincter (UES) physiology. Conventional HRM can yield imprecise measurements of UES resting pressure given its unidirectional sensors and averaging of circumferential pressure.

Measuring every particle's size from three-dimensional imaging experiments
, 2012 Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle, the consequences of this polydispersity are unknown as it is difficult to

Evaluation of Head Position in Static and Dynamic Three-Dimensional Imaging:a review of the Literature [PDF]
, 2017 Background: The interest in three-dimensional imaging in orthognathic treatment planning has been growing, especially for evaluation of the natural head position. Several three-dimensional devices are available on the market. Three-dimensional evaluation

Pitfalls of using three-dimensional CT colonography with two-dimensional imaging correlation.
AJR. American journal of roentgenology, 2001 137 T colonography is an imaging technique that enables both two-dimensional (2D) and three-dimensional (3D) evaluation of the colon [1–3]. Although debate continues regarding which rendering technique should be used for primary evaluation, the ...

Imaging Three Dimensional Two-particle Correlations for Heavy-Ion Reaction Studies
, 2005 We report an extension of the source imaging method for analyzing three-dimensional sources from three-dimensional correlations. Our technique consists of expanding the correlation data and the underlying source function in spherical harmonics and ...
