Word of the inventor
For approximately a decade, we have attended an industrial
revolution based on a control on a molecular scale of the manufacture of
objects with well defined function, the nanotechnology. So that this
scientific and technological revolution has a direction, it is necessary
that it is with the service certain urgent social requests and in
particular those related to health. We should consider instruments and
apparatuses solid, of low cost and miniaturized in order to satisfy at the
request of the medical experts who work under difficult environmental
conditions. Such requests cover multiple fields, among which radiotherapy X
occupies a place of first importance.
Since more than one
century, and under the initiative of Dr. Antoine Béclère in 1898, the
therapeutic use of the X-radiation became, with imagery X, one of the two
headlights applications of x-rays to progress towards a miniaturization of
the generator of x-rays we must use a source of electrons being able to
function at the ambient temperature, i.e. a cold cathode. This cold cathode
is the technological breakthrough, because its development was difficult
and delicate based on the operating conditions and the environment of sources
X.
Thanks to the
nanotechnology, we could develop recently in Lyon
the cold cathodes in carbon nanoperles. From their linear structures of
pure carbon spheres of dimension of a hundred nanometers, interlaced to
form a three-dimensional foam, the carbon nanoperles form a new material
which presents single and remarkable properties for the extraction of the
electrons at the ambient temperature. These cold cathodes will be at the
base of the development of our generators of miniaturized x-rays.
Our objective is to
put quickly on the market a portable x-ray gun for a conventional
therapeutic approach while minimizing the side effects. This short-term
objective will be concomitant with the development of a thorough
miniaturization of the generator of x-rays, which would authorize an
original, targeted and not very invasive radiotherapy X.
Good reading!
