Title: kV X-ray Digital Tomosynthesis Image Tracking of Respiratory Motion During The Delivery of MV Radiotherapy Treatment of Cancer
Speaker: Larry Partain
Director of Clinical Research, Silicon Valley Operations, TeleSecurity Sciences

Abstract Summary:
External beam radiotherapy, widely applied in the treatment of lung cancer, directs a beam of gamma rays from outside a patient to enter the patient's body to destroy a malignant lesion, as this focused treatment beam circles the patient's body, for a lesion positioned near the center of rotation. In free breathing patients, the cancer lesion can easily move up and down a cm or more during respiratory cycles (every 4 to 6 sec.) for continuous treatments that can typically last a minute or more. Since real time viewing of respiratory motion of objects has not usually been available during radiotherapy, the standard protocol delivers this lethal dose over the total volume traversed by the lesion during multiple breathing cycles. Unfortunately this directly kills about 2% of the patients treated and seriously injures a larger fraction due to the radiation damage to healthy surrounding tissues. The success of this x-ray tomosynthesis tracking technology has the potential to significantly reduce the magnitude of such collateral damage.

Biography Summary:
Larry Partain is the Director of Clinical Research for TeleSecurity Sciences. Much of his professional career has focused on translational research with electronic devices and systems that offer a promise to substantially improve management of cancer or other diseases.

Title: Giving Optical Vision to Nanorobots: Scanning Microlenses for Super-resolution Imaging
Speaker: Wen J. Li
President, IEEE Nanotech Council (Worldwide), Chair Prof Biomedical Engineering, City University of Hong Kong

Abstract Summary:
The resolution of optical microscopes has been constrained by Ernst Abbe's limit of diffraction to 200-250nm under visible light illumination since the 17th Century. The invention of the Scanning Electron Microscope (SEM) about 80 years ago and Scanning Tunneling Microscope/Atomic Force Microscope (STM/AFM) about 35 years have made tremendous breakthroughs in observing and analyzing sub-diffraction scale features.
Although non-optical technologies such as the SEM can provide resolution much beyond the optical diffraction limit, they are still mostly not compatible with real-time and non-destructive imaging (especially for biological samples) requirements, and therefore, a non-invasive and non-destructive imaging technology that can break the diffraction limit is still in demand.
In this lecture, we will present a novel time-efficient and non-invasive microsphere-based scanning superlens microscopy (SSUM) method that enables the observation of biological and non-biological samples over a large area with sub-diffraction limited resolution.

Biography Summary:
Wen J. Li (BSc/MSc, Univ. of Southern California, and PhD, UCLA) is Chair Professor of Biomedical Engineering in the Dept. of Mechanical and Biomedical Engineering of the City University of Hong Kong (CityU). He is currently the President of the IEEE Nanotechnology Council and Director of the Institute for Intelligent Cyber Physical Sensing Systems of the Shenzhen Academy of Robotics, China.

Cost is $6. Discount for IEEE members, students and unemployed. More details and registration is here.

Bio2device Group Meeting
The Bio2Device Group (B2DG) is a premier organization dedicated to all professionals in the Life Sciences industry within the San Francisco Bay Area. Membership is free and open to anyone in the Pharmaceutical, Biotechnology, Medical Device, Diagnostics, Healthcare, Life Science Tools, and Laboratory Service industries.

The Bio2Device Group's events provide the latest industry information through weekly educational programs and face-to-face interactive opportunities to build and maintain a career network. The educational talks are designed to help members keep up to date, continue to grow in their field, as well as explore other industry sectors and corporate functions.

Recently, IEEE has become aware of email scams or phishing attempts where IEEE volunteers are requested to send money or to provide access to sensitive information which the attackers may then use to conduct fraudulent or malicious activities. Attackers may send you email that looks like it is coming from legitimate sources, using actual names and email addresses of high-level IEEE leaders like Society Presidents, Section Chairs, and Conference Organizers. For example, the attacker may pose as an IEEE volunteer and ask you to transfer money or to reply with bank account information. In these situations, the email address used by the attacker may even look like it is coming from a legitimate address or an address you may be familiar with.

If you receive an email, call or text requesting that you take an action, even if it is consistent with the responsibilities of your current IEEE leadership role, but you are unsure if it is legitimate, please notify your supporting IEEE business unit and make them aware of the situation.

If you have questions or need assistance, please visit our FAQs on Phishing Attempts or reach out to the Contact Center where a service professional can assist you.
