GE Healthcare invests in a unique approach to cutting-edge CT
technology and acquires Prismatic Sensors AB, a leader in Deep
Silicon detector technology for photon counting computed tomography
(PCCT)
GE Healthcare today announced its acquisition of Prismatic
Sensors AB, a Swedish start-up specializing in photon counting
detectors, signifying the company’s continued investment in photon
counting CT technology. This technology has the potential to
establish a new standard of care in oncology, cardiology,
neurology, and many other clinical CT applications.
PCCT has the promise to further expand the clinical capabilities
of traditional CT, including the visualization of minute details of
organ structures, improved tissue characterization, more accurate
material density measurement (or quantification) and lower
radiation dose. Prismatic Sensors has overcome many challenges
working with silicon and patented a novel way to position the
silicon sensors “edge on” so the detector is deep enough to absorb
very high energy photons and fast enough to count hundreds of
millions of CT photons per second. The company was founded in 2012
as a spin-off from KTH Royal Institute of Technology in Stockholm,
Sweden.
“We believe this technology has the potential to be a
substantial step forward for CT imaging to establish a new
standard of care and eventually improve clinical outcomes for
millions of patients worldwide,” said Kieran Murphy, President
& CEO, GE Healthcare. “From the first x-ray machines to the
first photon counting CT prototype, GE Healthcare is committed to
pioneering next generation technologies to achieve precision health
and improve lives. We are excited about this cutting-edge approach
with Deep Silicon and its clinical potential.”
“Our research shows Deep Silicon is the best solution for
photon counting CT to meet clinical requirements,” says Mats
Danielsson, PhD, CEO of Prismatic Sensors, “Silicon is by far the
purest material produced for use in detectors. Alternative
materials, including cadmium-based, will be limited as x-ray
detector materials due to their imperfect crystal structure and
contaminations. Silicon-based detectors will enable superior
spectral resolution without compromising on count rate or spatial
resolution. Our collaboration with GE Healthcare has been very
productive and together, we have made rapid progress. Now, we look
forward to the next chapter as we come together as one team working
towards bringing photon counting CT with Deep Silicon detectors to
the market.”
For nearly 50 years, CT has proven to be a vital imaging tool
used to detect cancer, heart conditions, and other diseases large
and small. CT’s clinical use and diagnostic power have rapidly
increased with the introduction of volumetric imaging, faster
rotation speed, iterative and AI-based image reconstruction, as
well as dual energy. Last year, the United States reported an
all-time high in CT procedure volume with an estimated 91.4 million
scans1. Now, photon counting CT technology may have the potential
to define the next 50 years of CT innovation.
“It has been evident for decades that CT (and x-ray imaging)
would benefit greatly from energy-discriminating photon counting
detectors,” explains Norbert Pelc, Sc.D., Professor of Radiology,
Emeritus at Stanford University. “The challenge has been developing
detectors that can handle the very high photon flux from high-power
x-ray tubes while delivering good energy resolution and maintaining
or improving spatial resolution. Of course, the detectors also have
to be manufacturable at reasonable cost. It is a huge testament to
the scientists and engineers at Prismatic Sensors that they have
achieved this. I expect the impact on the CT field will be large,
for example, improved dose efficiency, particularly for low dose
acquisitions and for applications that benefit from tissue
specificity. To put the higher spatial resolution of this Deep
Silicon detector in perspective, we have not seen an improvement of
this magnitude in decades, and every other time that spatial
resolution was improved significantly the utility of CT also
advanced. This is very exciting.”
GE researchers began studying PCCT in 1993 and introduced the
world’s first PCCT prototype using cadmium-based detectors in 2006.
The company has been an industry leader in this technology for
Nuclear Medicine for a decade, providing excellent results to
clinicians and patients. Now, using Deep Silicon detectors, GE has
identified a better solution for CT to accommodate the much higher
count-rate demands of CT imaging, thereby providing much more
information to clinicians.
“Clinicians rely on the information they receive from medical
images – like those we receive from a CT – to help correctly
diagnose patients, monitor cases, and make treatment decisions,”
explains Staffan Holmin, MD, Professor in Clinical Neuroimaging,
Karolinska Institutet and Senior Consultant at Karolinska
University Hospital in Sweden. “What’s so exciting about photon
counting CT is that it brings higher spatial resolution and
contrast. This can help us to image small blood vessels, vascular
pathologies, and to see malignant changes at an earlier stage when
treatment can be more effective. The potential for substantially
reduced radiation is also important, particularly for pediatric
patients. Photon counting will likely become the standard of
care for all clinical applications where CT is used today.”
GE Healthcare expects to close the Prismatic Sensors acquisition
by January 2021, after holding a minority position in the company
since 2017. GE Healthcare and Prismatic Sensors will work together
to deliver a clinical system in the near future2. Terms of the
transaction are not disclosed.
