Wat info over het bericht van vorige week mbt het bezoek van GTAT aan Finland.
Sapphire quotte al:
"Last week GT Advanced Technologies (GTAT) traveled to Helsinki, Finland to showcase its Hyperion Technology for use in the treatment of cancer!"
Het artikel zelf kon ik niet lezen, maar gelukkig is er wel het eea over te vinden:
"Hyperion Accelerator Technology for BNCT
Li(p,n) is the primary neutron producing reaction considered for use in accelerator-based Boron Neutron Capture Therapy (BNCT). One key component of a clinically viable neutron generator for this approach is an accelerator technology that is capable of producing at least 20-30 mA of protons at 2.5 MeV. In order for large-scale commercialization of the technology to be successful, the accelerator must be straightforward to manufacture, simple to operate, low-cost and highly reliable.
GT Advanced Technologies’ Hyperion 4 accelerator is well suited for this application. Initially developed for use in proton-induced exfoliation, the Hyperion 4 is a single-ended electrostatic accelerator designed to operate at 40-50 mA and 2.0 MeV. It can readily be adapted to meet the demands of BNCT. We present the major Hyperion 4 design features and the operating conditions achieved to date"
Is wellicht wat technisch, maar wel interessant. Dan is er nog:
"The medical practice of radiation science is Radiology. Radiation Oncology is a segment of Radiology, and is distinguished as therapeutic rather than diagnostic.
The radiation treatment of cancer follows the general understanding that healthy tissues recovers better from exposure to any radiation as compared to diseased tissues. This phenomenon is enhanced by active cropping of the treatment beam, fractioning, and exposure angle control. In some circumstances, absorption of radiation is helped by disease-specific radiosensitizers or contrast agents.
Boron Neutron Capture Therapy (BNCT) is an alternative radiation oncology method that uses exposure to neutrons rather than gamma rays or x-rays. The technique relies on a type of radiosensitizer that couples boron atoms to a molecule with affinity to the tumor. Healthy tissue has little reaction with the neutron beam. Cancerous tissue that has boron uptake, however, is greatly affected.
Neutrons are absorbed into boron and boost the energy level of the nucleus of the atom. This higher energy state quickly drops to its normal level with the emission of an alpha particle. It is the energetic alpha particle that kills the surrounding diseased cells.
BNCT is a very active research technique, with many researchers actively seeking a portable neutron source. US., European, South American and Japanese researchers continue to pursue this approach to cancer therapy, and have actively sought a portable neutron source."
Wel wordt opgemerkt dat:
"boron neutron capture therapy is still in experimental stages"
Ik wist niet dat GTAT ook deze kant op ging, zal wel even duren voordat het wat wordt, maar ook dit heeft volgens mij zeker potentie!
