Mechanical Signals for Compensatory Lung Growth Assessed by High Resolution Computed Tomography
… dissertation involves the use of high resolution computed tomography (HRCT) to understand the role of intra-thoracic mechanical force and its distribution in regenerative growth in dogs i.e. to quantify lobar lung volumes and density gradients in normal and post-pneumonectomy (following lung …

Ex-Vivo Injection of Biomaterial Biologics for Treatment of Osteonecrosis
BACKGROUND: A loss of blood flow to bone produces osteonecrosis, characterized by cell necrosis and tissue destruction. This necrotic microenvironment induces chronic inflammation, poor bone regeneration, joint deformity, osteoarthritis, and potentially a total joint replacement. One potential …

Digital Microradiography: In Vitro Validation of a Novel Imaging Technique
… for the digital microradiography was 5 gray scales or 3.9 percent, which was comparable to digital radiography. The high concordance between conventional and digital microradiography was demonstrated by the mean and standard deviation of 8.69 and 1.75 gray scales respectively. There was a …

A Manufacturing Process for Single Micron Resolution Optical Gratings Used in X-ray Computed Tomography
X-ray Computed Tomography (CT) is a process that produces three-dimensional x-ray images, allowing for better diagnosis and analysis of complex internal medical conditions. New advances in the optical techniques used in this process promise to produce better results while reducing patient risk. One …

A survey of algebraic algorithms in computerized tomography
X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a sequence of two-dimensional reconstructions of the interior structure. This …
