Philips colors T. Rex Trix's tail using its Spectral CT technology
Philips IQon Spectral CT adds unique information to the medical record of T=
. Rex Trix
AMSTERDAM, Sept. 28, 2016 /PRNewswire/ -- Royal Philips (NYSE: PHG, AEX: PH=
IA), a leading health technology company, today presented the results of a =
Spectral CT scan of the tail vertebrae of Trix, a 66 million year old Tyran=
nosaurus Rex dinosaur. Working with Leiden's Naturalis museum in the Nether=
lands, Philips offered to scan one of the world's most complete and best pr=
eserved T. Rex skeletons. The aim of the scan was to evaluate how images of=
Trix's tail vertebrae obtained using Philips' IQon Spectral CT imaging dif=
fer from conventional CT images, and to provide a level of detail not visib=
le to paleontologists until now. =
Trix, who was discovered in Montana, USA, in 2013, was purchased by the Nat=
uralis museum and transported to the Netherlands on August 23, 2016. For 66=
million years this carnivorous dinosaur lay buried in the rocks. As the or=
ganic matter had virtually all disappeared, only the skeleton was left, and=
over the millennia a mineralization process took place. As a result, Trix'=
s fossilized bones can be considered 'remineralized' representations of her=
original bones. =

The smaller bones in the tail of a T. Rex fossil are often missing, lost to=
scavenging or washed away by currents prior to burial and fossilization. I=
ntact smaller tail elements of a T. Rex are therefore rare, and Philips was=
not aware of much prior work on the internal structure of these elements. =
However, Trix has a beautifully preserved tail. Paleontologist and dinosaur=
expert Anne Schulp of Naturalis was keen to examine Trix's vertebrae in gr=
eater detail. On August 31, her four tail vertebrae (C20 =96 C23) were scan=
ned on a Philips IQon Spectral CT scanner in Best, in the Netherlands.
"We have already looked at some of the bones using a regular medical CT sca=
nner, but we had a little problem," said Anne Schulp, Paleontologist and di=
nosaur expert at Naturalis. "There is a deposit of pyrite =96 an iron rich =
mineral that blurs the complete picture because it absorbs the X-rays. So b=
asically we required a different technology."
Philips IQon is the world's first detector-based spectral CT scanner. In ad=
dition to its unique dual-layer detector, it makes use of advanced spectral=
reconstruction algorithms. By combining these two technologies, the IQon i=
s able to obtain detailed images of objects that are otherwise difficult to=
scan, such as Trix's tail vertebrae.
"The IQon filters out all the 'noise,' as it were, thereby providing a real=
ly good insight into the bone structure and how it is built up," explained =
Anne Schulp. "It's basically making the step from black and white movies to=
color. In this way, we are able to add depth to Trix's medical records: we=
make the invisible visible. It's just really hard to describe the sensatio=
n of finding something, seeing something that no one else has ever seen."
These scans are just the first images. Further investigations will provide =
even more insights to build up Trix's medical record. Over the next few mon=
ths, on-going research with medical experts will aim to reveal more details=
about Trix's life.
"What the IQon is doing is acquiring two different X-ray energy levels in a=
single acquisition. It's fantastic to see how a detailed three-dimensional=
image is built up," said Julien Milles, Clinical Scientist CT Health Syste=
ms, Philips Benelux. "With Trix, we were able to identify and color-highlig=
ht bone structure, even with 'remineralized' versions of the original bones=
. So in one picture it is just one white blob. And then all of a sudden, at=
the click of a mouse, there is the next one where all the details in the b=
one pop up. And that with a 66 million year old lady!"
This isn't the first time Philips' imaging technology has been leveraged fo=
r unearthing secrets of the past. In 2015, Philips' CT scanners were used t=
o study bones of the bodies of people who died in Pompeii, giving archeolog=
ists a view into the daily lives, health and habits of the citizens of Pomp=
eii.
