Our country first small launch fault scanning meter (PET) develops in the high
energy successfully, initially tests the result indicates the technical specification
basically meets the design requirements. This item is together subsidizes by the Academia
Sinica knowledge innovation instrumentation equipment development key project and the high
energy knowledge innovation item, the high energy grasps the independent intellectual
property rights, provided the safeguard for the item following development.
the launch fault scanning meter (PET) is the present most advanced nuclear medicine
imagery equipment, has been widely applied in the medical diagnosis, the medicine
development and the basic research. It uses the mark radioactive medicine
carries on to the biology in vivo physiology or the biochemistry process ??, not creates
through the fault imagery way obtains biology in vivo the function information. Small PET
is specially designs for the small animal experiment. Because the animal experiment holds
the extremely important position in the biology medicine research, the new medicine and
the treatment method needs first to carry on on the animal body, therefore small PET has
the broad application prospect.
The small animal small are very more than the human body, therefore small PET spatial
resolution and so on main target must far be higher than human body PET, greatly increased
the small PET development difficulty. In the item triturating, needs to grasp and to solve
the solid detector, the low noise simulation electronics, high speed parallel data
gathering and so on many technical questions. In order to achieve the high resolution, the
item group in in the full investigation and study international development tendency
foundation, used LSO the crystal array coupling position keen PMT detector technology
plan. Used the assembly line in the electronics system , the LVDS serial output, FPGA data
processing, position energy LUT long-distance downloads, unification mainstream technology
and so on clock assignment, TCP/IP data transmission, caused the system speed and the
stability obtains the guarantee.
