Abstract:Infinia Hawkeye 4, a multi-functional radionuclide imaging device of GE, is widely used and has a high cost performance.
The functions, architecture and faults of the wireless bridge of Infinia Hawkeye 4 were analyzed in depth. Based on the function,
architecture and failure of Infinia Hawkeye 4 wireless bridge, we proposed a solution using routers of non-original specifications to
replace it, and provided a specific implementation plan and implementation process. Analysis of the implementation effect of the
scheme showed that the scheme could realize the related functions of the original router, and the communication speed was improved.
In addition, the feedback results were good after popularization and application to other medical institutions, and the longest
failure-free operation time of wireless bridge after replacement maintenance had reached 48 months.
