EXPLORER, the world’s first medical imaging scanner that can capture a 3-D picture of the whole human body at once, has produced its first scans.
The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined positron emission tomography (PET) and x-ray computed tomography (CT) scanner that can image the entire body at the same time. Because the machine captures radiation far more efficiently than other scanners, EXPLORER can produce an image in as little as one second and, over time, produce movies that can track specially tagged drugs as they move around the entire body.
The developers expect the technology will have countless applications, from improving diagnostics to tracking disease progression to researching new drug therapies… Continue reading....
The new total-body PET/CT scanner could revolutionize our understanding and treatment of disease through analysis of better imaging data from the whole body. In The Journal of Nuclear Medicine (JNM) featured January article, scientists at the University of California, Davis (UC Davis), outline the development and benefits of this innovative diagnostic tool and explain how maximizing PET sensitivity will advance clinical research and patient care.
Positron emission tomography (PET) is widely considered the most sensitive technique available for non-invasively studying physiology, metabolism and molecular pathways in the living human being. However, there have been drawbacks, including low signal-to-noise ratio (SNR) affecting image quality, long imaging times and concerns regarding radiation dose.
Total-body PET, which encompasses the entire body within the field of view and allows imaging of all the tissues and organs of the body simultaneously, promises to be a game changer… Continue reading....
DAVIS, Calif.; January 4, 2017–The National Academy of Inventors has elected Simon Cherry, distinguished professor in the UC Davis Department of Biomedical Engineering, to its 2016 class of fellows.

The academy accords fellowship status to “academic inventors who have demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on quality of life, economic development and the welfare of society.”
The academy recognized Cherry for his work on medical imaging technology, especially positron emission tomography (PET) scanning and computed tomography.
This new recognition caps off a banner year for Cherry – he was elected a fellow to three prestigious academies in 2016. In November, he was elected a fellow of the American Association for the Advancement of Science, and in February he was elected to the National Academy of Engineering.
Cherry received his Ph.D. in medical physics in 1989 from the University of London. He was a faculty member at UCLA for eight years before joining UC Davis in 2001....
DAVIS, Calif.; November 30, 2016–The American Association for the Advancement of Science (AAAS) has elected Simon Cherry, distinguished professor in the UC Davis Department of Biomedical Engineering, to its newest class of fellows.Simon Cherry is a distinguished professor in the UC Davis Department of Biomedical Engineering.Cherry is pioneering new medical imaging technologies to improve cancer detection and treatment. In 2015, the National Institutes of Health awarded Cherry and his colleague, Ramsey Badawi, a $15.5 million grant to develop the world’s first total-body PET scanner. This scanner allows all tissues and organs to be imaged simultaneously with 40 times more sensitivity than current combination PET/CT scanners. It also reduces a patient’s radiation exposure dramatically. Instead of taking 20 minutes to complete a scan this method requires only 30 seconds.Cherry received his Ph.D. in medical physics in 1989 from the University of London.

Simon Cherry, a Distinguished Professor in the UC Davis Department of Biomedical Engineering (BME), and co-leader of the UC Davis Comprehensive Cancer Center’s Biomedical Program, has been elected to the National Academy of Engineering. Cherry is being acknowledged for research that has put UC Davis on the leading edge of molecular imaging nationwide.
He is the 20th member of the UC Davis College of Engineering faculty to be elected to the prestigious academy. Cherry and the other members of this year’s newly elected class, including UC Davis engineering alum Adam Steltzner, will be inducted formally during a ceremony at the NAE’s annual meeting in Washington, D.C., on Oct. 9.
This honor follows October’s announcement that Cherry and BME colleague Ramsey Badawi, an associate professor of radiology and a PET physicist, received a five-year, $15.5 million National Cancer Institute Transformative Research Award grant to build a combination PET-CT whole-body scanner, which could drop the patient’s radiation dose by a factor of 40, or decrease scanning time from 20 minutes to 30 seconds. Such quick scans also could reduce the incidence of images blurred by patient movement....
A University of California, Davis, research team has been awarded $15.5 million to build the world’s first total-body positron emission tomography scanner, which could fundamentally change the way cancers are tracked and treated and put the university on the nation’s leading edge of molecular imaging.
The Transformative Research Award, part of the National Institutes of Health High-Risk, High-Reward Program, supports bold and untested ideas that have the potential to be paradigm shifting. This award is one of eight given in the transformative research category in 2015. The five-year grant, administered by the National Cancer Institute, will fund the EXPLORER project, led by Simon Cherry, distinguished professor of biomedical engineering at UC Davis, and Ramsey Badawi, professor of radiology.
Positron emission tomography, or PET, scans are widely used to diagnose and track a variety of diseases, including cancer, because they show how organs and tissues are functioning in the body (in contrast to MRI or CT scans, which mostly show anatomy). The EXPLORER project would address shortcomings of the current scanning technology, which requires more time and exposes the patient to more radiation because scans are done in 20-centimeter segments.
“The vision of the EXPLORER project is to solve two fundamental limitations of PET as it is currently practiced,” said Cherry. “The first is to allow us to see the entire body all at once. The second huge advantage is that we’re collecting almost all of the available signal, which means we can acquire the images much faster or at a much lower radiation dose. That’s going to have some profound implications for how we use PET scanning in medicine and medical science.”
Cherry and Badawi predict that by seeing the entire body simultaneously, their scanner could drop the radiation dose by a factor of 40 or decrease scanning time from 20 minutes to just 30 seconds. A quicker scan also could reduce the incidence of images blurred by patient movement....
