Bubble Dynamics and Acoustic Droplet Vaporization in Gas Embolotherapy.
(2014)
Gas embolotherapy is a twist on traditional catheter based embolotherapy approaches. Localized gas bubbles generated are used in place of solid emboli normally used to restrict blood flow. The gas bubbles are formed ...
Subcutaneous tissue response to titanium, poly(ϵ‐caprolactone), and carbonate‐substituted hydroxyapatite‐coated poly(ϵ‐caprolactone) plates: A rabbit study
(Wiley Subscription Services, Inc., A Wiley Company, 2013-08)
The aim of this study was to evaluate the soft tissue response to poly(ϵ‐caprolactone) (PCL) implants with and without carbonate‐substituted hydroxyapatite (CHA) coating compared to the commonly used titanium alloy ...
Advanced Microspheres as Injectable Cell Carriers for Tissue Engineering.
(2015)
Biodegradable polymer microspheres have emerged as injectable cell carriers
for the regeneration and repair of irregularly-shaped tissue defects. The physical structure and chemical composition of the microsphere are ...
Antibacterial Perfluorocarbon Ventilation: A Novel Treatment Method for Bacterial Respiratory Infections.
(2015)
Bacterial respiratory infections significantly contribute to the morbidity and mortality associated with lung diseases such as cystic fibrosis, chronic obstructive pulmonary disease, and bronchiectasis. These patients ...
Statistical Emission Image Reconstruction for Randoms-Precorrected PET Scans Using Negative Sinogram Values
(IEEE, 2003-10-19)
Many conventional PET emission scans are corrected for accidental coincidence (AC) events, or randoms, by real-time subtraction of delayed-window coincidences, leaving only the randoms-precorrected data available for image ...
Polysorbate cationic synthetic vesicle for gene delivery
(Wiley Subscription Services, Inc., A Wiley Company, 2011-03-01)
Synthetic nonionic surfactant vesicles (niosomes) are a colloidal system with closed bilayer structures, displaying distinct advantages in stability and cost compared with liposomes. In this article, polysorbate cationic ...
Simultaneous Multislice Functional Magnetic Resonance Imaging.
(2016)
Functional magnetic resonance imaging (fMRI) is a valuable tool for mapping brain activity in many fields. Since functional activity is determined by temporal signal changes, undesired fluctuations from physiological motion ...
Effect of Including Detector Response in SPECT Quantification of Focal I-131 Therapy
(IEEE, 2001-11-04)
With a regularized strip-integral (1D) SAGE reconstruction, circular-orbit SPECT estimates of phantom focal 131-I activity vary with changes in the level of uniform background. They also vary with changes in image resolution ...
Intensity-Based Image Registration Using Robust Correlation Coefficients
(IEEE, 2004-11-01)
The ordinary sample correlation coefficient is a
popular similarity measure for aligning images from the same
or similar modalities. However, this measure can be sensitive to
the presence of “outlier” objects that appear ...
Incorporation of System Resolution Compensation (RC) in the Ordered-Subset Transmission (OSTR) Algorithm for Transmission Imaging in SPECT
(IEEE, 2006-06-26)
In order to reconstruct attenuation maps with improved spatial resolution and quantitative accuracy, we developed an approximate method of incorporating system resolution compensation (RC) in the ordered-subset transmission ...
