A synchrotron light-source is a source of electromagnetic radiation (E/M-R),
usually produced by synchrotrons,
microtrons and electron storage-rings,
for scientific and technical purposes.
The extracted high-energy electron-beam can be directed into auxiliary components,
bending magnets and insertion devices (undulators or wigglers),
in storage rings and free electron LASERs,
supplying the strong magnetic fields,
perpendicular to the beam,
needed to convert the electrons' cinetic energy,
into quasi-monochromatic photons,
ranging from Infrared up to X-rays,
forming a tunable Free Electron LASER (FEL) .
Methods and Materials
The innovation trail of quasi-monochromatic X-Ray sources,
from 1960 to 2015,
as it is reflected on relevant Industrial Property (IP) documents,
such as ,
has been followed,
in order to outline the miniaturization process that seems to lead towards tunable,
desk-top sized FELs,
into a modern Medical Imaging Laboratory.
Plasma acceleration is a technique for accelerating charged particles,
such as electrons,
positrons and ions,
using an electric field associated with electron plasma wave or other high-gradient plasma structures (like shock and sheath fields).
All IP-Docs relevant to Synchrotron,
FEL and CLS have been searched,
in the on-line esp@cenet search-engine of the European Patent Office (EPO).
In total 872 relevant IP-Docs have been retrieved and evaluated.
This search has led to the Idustrial Property Documents that constitute the innovation kernel of the present break-through in the field of Compact Light Sources and their implementation in a way that directly serves Medical Imaging and especially Cardiac Radiology,
as a really disrupting technology,
after Wilhelm Conrad Röntgen and Sir Godfrey...
related to CLS,
have been found innovative and promising.
The disclosed innovation of some of these IP-Docs, has already been used for the development of new Systems (e.g.
the "miniature-synchrotron" in TUM/LMU Munich,
since May 2015).
as for example EP2846422A1,
disclose smart approaches,
such as a fiber-driven FEL,
feeding aLASER Wake-field Accelerator (LWFA),
creating a UV/Soft-X-Ray light-source,
promising another step towards affordable and compact medical-imaging CLS.
It is not easy to predict the exact evolution of Compact Light Sources,
