Phase-calibration for imaging flow cytometry

Abstract:

Aspects of the present disclosure include methods for phase correcting signals from a light detection system (e.g., in a flow cytometer). Methods according to certain embodiments include detecting light from a sample having particles in a flow stream with a light detection system that includes a brightfield photodetector configured to generate a brightfield data signal and a fluorescence detector configured to generate a fluorescence data signal and calculating a phase correction for the fluorescence detector based on the relative phase between the brightfield data signal and the fluorescence data signal. Systems having a processor with memory operably coupled to the processor having instructions stored thereon, which when executed by the processor, cause the processor to calculate a phase correction for a fluorescence detector based on a brightfield data signal and a fluorescence data signal from the fluorescence detector are also described. Integrated circuit devices (e.g., field programmable gate arrays) having programming for practicing the subject methods are also provided.
