May 12,2009—Hong Kong International Airport(HKIA), which serves approximately 48 million passengers per year on flights to 150 locations,is now using RFID baggage tags for 100 percent of the 40,000 bags that leave the airport every day.HKIA has upgraded its former bar-code-based system with radio frequency identification, at a cost of HK$50 million(US$6.5 million).展开更多

The backscatter signal is treated as an emitter in a non-uniformly attenuating medium. This type of tomography has applications in radiology and dentistry for which metals effectively block the transmission of X-rays. Scanning for metals also has applications in security/baggage screening. The results show that when the forward scattering angle is zero, the algorithm, with a redefinition of the density function f, reduces to the PET attenuation correction.展开更多
