Madrid: Researchers
from the Pompeu Fabra University in Spain have created a high
resolution atlas of the heart based on 3D images taken from 138
people.
"This atlas is a statistical description of how the heart and its
components -- such as the ventricles and the atrium -- look,"
Corne Hoogendoorn, researcher at Pompeu Fabra University's CISTIB
centre, told SINC, the news agency of the Spanish Foundation for
Science and Technology FECYT.
The study can be applied to medical imaging, especially when
segmenting, or in other words, properly differentiating a
structure to be analysed from the rest of the image, the journal
IEEE Transactions on Medical Imaging, reports.
IEEE stands for the Institute of Electrical and Electronics
Engineers.
The level of detail and the possibility to extend the atlas give
it "an advantage over the majority of cardiac models present to
date", adds Hoogendoorn, according to a Pompeu Fabra statement.
Pompeu Fabra scientists have managed to create a representation of
the average shape of the heart and its variations with images from
138 fully functioning hearts taken using multi-slice computed
tomography. This technique offers 3D and high resolution X-ray.
To create this cardiac map, researchers developed a statistical
model capable of managing high quantities of information provided
by individual images. It can also collect temporary variations,
given that the heart is never motionless.
