Elastography Method for Reconstruction of Nonlinear Breast Tissue Properties
(Hindawi, 2009-07-09)Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. In this paper a nonlinear elastography method is introduced for reconstruction of complex ... -
Temperature-Change-Based Thermal Tomography
(Hindawi, 2009-07-22)Thermal properties of biological tissues play a critical role in the study of tumor angiogenesis and the design and monitoring of thermal therapies. To map thermal parameters noninvasively, we propose temperature-change-based ... -
A General Total Variation Minimization Theorem for Compressed Sensing Based Interior Tomography
(Hindawi, 2009-11-17)Recently, in the compressed sensing framework we found that a two-dimensional interior region-of-interest (ROI) can be exactly reconstructed via the total variation minimization if the ROI is piecewise constant (Yu and ... -
Tissue engineered devices for ligament repair, replacement and regeneration
(Academic Journals, 2009-12-29)The anterior cruciate ligament (ACL) is one of five ligaments in the knee that are important for stability and kinematics. It is also the most commonly injured ligament of the knee and due to its poor healing potential, ... -
Varying Collimation for Dark-Field Extraction
(Hindawi, 2010-02-16)Although x-ray imaging is widely used in biomedical applications, biological soft tissues have small density changes, leading to low contrast resolution for attenuation-based x-ray imaging. Over the past years, x-ray ... -
SART-Type Image Reconstruction from a Limited Number of Projections with the Sparsity Constraint
(Hindawi, 2010-04-26)Based on the recent mathematical findings on solving the linear inverse problems with sparsity constraints by Daubechiesx et al., here we adapt a simultaneous algebraic reconstruction technique (SART) for image reconstruction ... -
Compressed Sensing Inspired Image Reconstruction from Overlapped Projections
(Hindawi, 2010-06-22)The key idea discussed in this paper is to reconstruct an image from overlapped projections so that the data acquisition process can be shortened while the image quality remains essentially uncompromised. To perform image ... -
SART-Type Image Reconstruction from Overlapped Projections
(Hindawi, 2010-09-05)To maximize the time-integrated X-ray flux from multiple X-ray sources and shorten the data acquisition process, a promising way is to allow overlapped projections from multiple sources being simultaneously on without ... -
Inverse Fourier Transform in the Gamma Coordinate System
(Hindawi, 2010-10-26)This paper provides auxiliary results for our general scheme of computed tomography. In 3D parallel-beam geometry, we first demonstrate that the inverse Fourier transform in different coordinate systems ... -
Towards the creation of decellularized organ constructs using irreversible electroporation and active mechanical perfusion

A theoretical framework of x-ray dark-field tomography
(Siam Publications, 2011)X-ray mammography is currently the most prevalent imaging modality for screening and diagnosis of breast cancers. However, its success is limited by the poor differentiation between healthy and diseased tissues in the ... -
Biomechanics of hair cell kinocilia: experimental measurement of kinocilium shaft stiffness and base rotational stiffness with Euler-Bernoulli and Timoshenko beam analysis
(Company of Biologists Ltd., 2011-03-01)Vestibular hair cell bundles in the inner ear contain a single kinocilium composed of a 9+2 microtubule structure. Kinocilia play a crucial role in transmitting movement of the overlying mass, otoconial membrane or cupula ... -
A Parametric Study Delineating Irreversible Electroporation from Thermal Damage Based on a Minimally Invasive Intracranial Procedure
(2011-04-30)Background Irreversible electroporation (IRE) is a new minimally invasive technique to kill undesirable tissue in a non-thermal manner. In order to maximize the benefits from an IRE procedure, the pulse parameters and ... -
Successful Treatment of a Large Soft Tissue Sarcoma With Irreversible Electroporation
(American Society of Clinical Oncology, 2011-05-01)Irreversible electroporation (IRE) is a promising technique for the focal treatment of pathologic tissues that involves placing minimally invasive electrodes within the targeted region. A series of short, intense electric ... -
Use of Imaging Biomarkers to Assess Perfusion and Glucose Metabolism in the Skeletal Muscle of Dystrophic Mice
(2011-06-04)Background Duchenne muscular dystrophy (DMD) is a severe neuromuscular disease that affects 1 in 3500 boys. The disease is characterized by progressive muscle degeneration that results from mutations in or loss of the ... -
Effect of Localized Mechanical Indentation on Skin Water Content Evaluated Using OCT
(Hindawi, 2011-08-04)The highly disordered refractive index distribution in skin causes multiple scattering of incident light and limits optical imaging and therapeutic depth. We hypothesize that localized mechanical compression reduces ... -
Effects of acute ingestion of different fats on oxidative stress and inflammation in overweight and obese adults.
(2011-11-07)Background Studies show that obese individuals have prolonged elevations in postprandial lipemia and an exacerbated inflammatory response to high fat meals, which can increase risk for cardiovascular diseases. As ... -
High-frequency irreversible electroporation (H-FIRE) for non-thermal ablation without muscle contraction
(2011-11-21)Background Therapeutic irreversible electroporation (IRE) is an emerging technology for the non-thermal ablation of tumors. The technique involves delivering a series of unipolar electric pulses to permanently destabilize ... -
Computational and experimental study of chemotaxis of an ensemble of bacteria attached to a microbead
(American Physical Society, 2011-12-12)Micro-objects propelled by whole cell actuators, such as flagellated bacteria, are being increasingly studied and considered for a wide variety of applications. In this work we present theoretical and experimental ... -
Nonlinear Elasto-Mammography for Characterization of Breast Tissue Properties
