Hardware-friendly bi-exponential fluorescence lifetime imaging algorithms and phasor approaches

摘要

A newly developed hardware-friendly non-iterative fluorescence lifetime imaging (FLIM) analysis method was verified in an FPGA chip. Its performances were also demonstrated on two-photon FLIM images of gold nanorods (GNRs)-Cy5 labelled Hela cells. The results obtained by the proposed method can be presented in a polor plot to be compared to the widely used phasor (Phasor) approach. Combining our method with Phasor will be very useful in FLIM analysis.
