and family

Welcome to our website. We established in the early days of the internet to share adventures with family and friend in pictures and video. On the family side we also include some historical data. This is an update of this now 21-year-old site to take advantage of the much higher network speeds we have today. Our adventures include travel, family outings, research results, investments, and photograpy of all kinds. We cover physics and medical technology as well as travel to remote parts of the globe.



Who I Am

Douglas P. Boyd, Ph.D.


Dr. Boyd has contributed to the fields of imaging technology, accelerator and beam physics, superconducting systems, nuclear physics, and medical physics.   Following his graduate studies in nuclear physics at Rutgers, Dr. Boyd continued his research at Bell Labs under a post-doctoral fellowship program.  He then moved to Stanford University and was the project leader for the world’s first pion radiotherapy facility.  As part of this program, he was one of the early developers of fan-beam CT scanners using Xenon-detectors.   The resulting patents were licensed by Stanford to General Electric, who in turned sublicensed all CT manufacturers in Europe, U.S. and Japan.  These patents generated a major royalty stream to Stanford through 1998.  In 1976 Dr. Boyd joined the faculty in at UCSF with the intent to establish a laboratory to develop the next generation of no-motion CT scanners, with emphasis on cardiac imaging.  This led to the foundation of Imatron, Inc., which since 1982 became the leader in development of Electron Beam Cardiac CT Scanners (EBCT).  From 1986 to 2001 when the company was acquired by General Electric, more than 300 EBCT systems were produced and sold worldwide.  The use of these scanners for early detection heart disease helped revolutionize the management or coronary artery disease.   Dr. Boyd’s team also pioneered in a number of related imaging developments, including the research leading to the first successful explosive detection scanners for airports, for which he was awarded the prestigious Safe Skies award in 1992.   This research led to formation of InVision Technologies, Inc, a company that since 1990 pioneered in the development of modern CT explosive detection systems that are installed at most major airports in the world today.  As a director of Invision, Boyd helped the company become the leading supplier of Airport explosives detection systems until the sale of the company to GE in 2003. In 2006, realizing that EDS technology had not yet reached its full potential, Dr. Boyd along with Dr. Sam Song established TeleSecurity Sciences with the objective to automate the threat resolution process. In 2017 Imatrex Inc was established to continue the work of Imatron Inc in Medical Imaging and to develop new approaches to image guided cancer therapy. Under a Russian Contract, Imatrex developed the next generation EBCT scanner with a 28msec scan speed and 16cm of 1/2 mm slices called Dual-Slice EBCT. This advanced scanner was returned to Russia shortly after the Russian-Ukraine war began in Feb 2022 and before reaching FDA certification. The EBCT technology was recently licensed  to a new startup company, Nautilus Inc, who will develop a 3rd generation EBCT using newly invented technology.
