Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...

purpose: since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. the primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the dev...

In this paper, the application of supervised descent method (SDM) for 2-D microwave thorax imaging is studied. The forward modeling problem solved by finite element-boundary integral (FE-BI) method. According to prior information human thorax, a 3-ellipse training set generated offline. Then, average direction between an initial background model and models calculated. Finally, reconstruction te...

In this paper, the authors prove that variations in thoracic volumes are greatly responsive to the act of breathing (i.e., inspiration and expiration). These variations may be adopted for diagnosing various respiration related diseases and pulmonary edema. In this study, the authors present a method to estimate the thoracic volume non-invasively using anthropometric dimensions. The change in th...

PURPOSE The purpose of this study was to develop a methodology to quantitatively measure the thorax-to-abdomen breathing ratio from a 4DCT dataset for breathing motion modeling and breathing motion studies. METHODS The thorax-to-abdomen breathing ratio was quantified by measuring the rate of cross-sectional volume increase throughout the thorax and abdomen as a function of tidal volume. Twent...
