The challenges of lung cancer radiotherapy are intra/inter-fraction tumor/organ anatomy/motion changes and the need to spare surrounding critical structures. Evolving radiotherapy technologies, such as four-dimensional (4D) image-based motion management, daily on-board imaging and adaptive radiotherapy based on volumetric images over the course of radiotherapy, have enabled us to deliver higher...

The paper describes a concept of innovative assistive motion therapy devices with new patent pending fluidic actuators. The main novelty of these soft actuators is the rotary fluid motor with elastic chambers (REC), which produces rotational motion without any additional transmission elements. The key actuator features as inherent compliance, high back-driveability and light-weight design build...

Photocatalytic micromotors that exhibit wireless and controllable motion by light have been extensively explored for cancer treatment photodynamic therapy (PDT). However, overexpressed glutathione (GSH) in the tumor microenvironment can down-regulate reactive oxygen species (ROS) level therapy. Herein, we present dendrite-shaped light-powered hematite microrobots as an effective GSH depletion a...

OF THE DISSERTATION Improving Radiation Therapy Through Motion Tracking by Hanlin Wan Doctor of Philosophy in Biomedical Engineering Washington University in St. Louis, 2016 Parag Parikh, Chair Radiation therapy is a widely-used cancer treatment method in which lethal doses of ionizing radiation are delivered to cancerous cells. Given the high dose requirements and the risk of associated compli...

background hands burn was associated with significant functional disorders that severely affected patient’s quality of life. the aim of this study was to examine the effect of educational program based on exercise therapy on burned hand function. methods this experimental research was conducted in a period of ten months in 2010-2011 in mottahari hospital in tehran in iran. the sample included 6...

Background: The shoulder joint internal rotation deficit is inter alia the most important risk factors for throwing athletes. Thus, the present study aims at investigating the effect of eight weeks of rotator cuff muscles’ specific exercises on the range of motion, proprioception and the activation time of the selective shoulder muscles in male volleyball players with shoulder joint inter...
