Technological advances have influenced practice patterns and innovation in many health disciplines, including respiratory therapy. Collaborative approaches and knowledge-sharing environments are vital in addressing problems and adopting emerging technology. This article illustrates how the emergence of low-cost three-dimensional printing technology to physically reproduce the results of compute...

The major problem with ventilation distribution calculations using DIR and 4DCT is the motion artifacts in 4DCT. Quite often not all phases would exhibit mushroom motion artifacts. If the ventilation series similarity is sufficiently robust, the ventilation distribution can be calculated using only the artifact-free phases. This study investigated the ventilation similarity among the data deriv...

The advent of three-dimensional printing (3DP) technology has enabled the creation of a tangible and complex 3D object that goes beyond a simple 3D-shaded visualization on a flat monitor. Since the early 2000s, 3DP machines have been used only in hard tissue applications. Recently developed multi-materials for 3DP have been used extensively for a variety of medical applications, such as persona...

In this review, we revisit our latest works regarding the description of gravitational interaction on noncommutative spaces as matrix models. Specifically, inspired by gauge-theoretic approach (ordinary) gravity, make use suggested methodology, modified appropriately for framework, well-established formulation gauge theories them. Making a covariant four-dimensional fuzzy space, formulate theor...

Motivated by a motion detection system the application of a new category of Kohonen‘s Self-Organizing Map (SOM) [8] is presented in this paper. Based on earlier work of Seiffert and Michaelis on three-dimensional SOMs [10], [11] a new implementation of growing multi-dimensional SOMs, the Quasi-Four-Dimensional Neuroncube (QFDN), has already been introduced in [12]. This paper focuses on the app...

PURPOSE To assess the temporal and spatial accuracy of the GateCT™ system (VisionRT, London, UK), a recently released respiratory tracking system for 4DCT, under both ideal and nonideal respiratory conditions. METHODS Three experiments were performed by benchmarking and comparing its results with the ground-truth input data and those generated by the widely used Varian RPM™ system (Real-time ...

How structure relates to function--across spatial scales, from the single molecule to the whole organism--is a central theme in biology. Bioengineers, however, wrestle with the converse question: will function follow form? That is, we struggle to approximate the architecture of living tissues experimentally, hoping that the structure we create will lead to the function we desire. A new means to...
