US Patent 10180398 Trajectory-based triggering system for hyperspectral imaging flow cytometer

A hyperspectral imaging flow cytometer can acquire high-resolution hyperspectral images of particles, such as biological cells, flowing through a microfluidic system. A trajectory-based triggering system can be used that will only trigger the acquisition of a hyperspectral image when an appropriate particle or cell is crossing an imaging line, thereby saving valuable resources and time. The hyperspectral imaging flow cytometer can provide detailed spatial maps of multiple emitting species, cell morphology information, and state of health. An optimized system can image about 20 cells per second. The hyperspectral imaging flow cytometer enables many thousands of cells to be characterized in a single session.
