We have previously developed a robotic ultrasound imaging system for motion monitoring in abdominal radiation therapy. Owing to the slow speed of image processing, our previous could only track motions under breath-hold. To overcome this limitation, novel 2D-based processing method tracking intra-fraction respiratory is proposed. Fifty-seven different anatomical features acquired from 27 sets 2D sequences were used study. Three with three healthy volunteers. The remaining datasets provided...

The purpose of this study was to explore the feasibility therapeutic angiogenesis in myocardial infarction induced by hepatocyte growth factor (HGF) mediated ultrasound-targeted microbubble destruction. Methods. Forty Wistar rats were divided into 4 groups after models prepared: (1) HGF, ultrasound, and microbubbles (HGF+US/MB), (2) HGF (3) microbubbles, (4) surgery alone. Destruction loaded with gene an electrocardiographic trigger mode performed HGF+US/MB group. All killed being...
Abstract Purpose Stereotactic body radiation therapy (SBRT) allows for high doses to be delivered the pancreatic tumors with limited toxicity. Nevertheless, respiratory motion of pancreas introduces major uncertainty during SBRT. Ultrasound imaging is a non‐ionizing, non‐invasive, and real‐time technique intrafraction monitoring. A configuration not available place ultrasound probe SBRT Methods Materials An arm‐bridge system was designed built. CT scan bridge‐held acquired fused ten...
A high-spectral-resolution lidar (HSRL) is proposed to retrieve the seawater volume scattering function at 180° angle βπ without assumption of extinction-to-backscatter ratio. field-widened Michelson interferometer employed as ultra-narrow spectral discriminator reject particulate and molecular Rayleigh but transmit Mandelshtam-Brillouin scattering. The theoretical framework presented in detail based on a dual-channel HSRL configuration. Simulation retrieval error estimation shows that,...

Abstract Disproportionation of the liquid mixed anhydride dimethacrylic sebacic (m‐SA) to methacrylic and polyanhydride oligomers, as well vinylic polymerization, can occur on workup storage at room temperature. Dimethacrylic 1,3‐bis( p ‐carboxyphenoxy) propane, being a solid, also disproportionate, but propensity do so is lower than for m‐SA. These events be suppressed with free‐radical inhibitors, inhibitor 2+3‐ t ‐butyl‐4‐methoxyphenol more effective stabilizer 4‐methoxyphenol 20 °C. ©...
<h2>Abstract</h2> Xerostomia is the most common late toxicity after head and neck radiation. We demonstrate injection of a hydrogel spacer anteriorly displacing submandibular gland. This procedure enables reduced dose to displaced gland in cadaveric models oropharynx cancer treated with IMRT, potential implications reducing xerostomia risk.
