A cross sectional imaging system performs high-resolution, high-speed partial imaging of cells. Such a system may provide much of the information available from full imaging cytometry, but can be performed much more quickly, in part because the data analysis is greatly reduced in comparison with full image cytometry. The system includes a light source and a lens that focuses light from the light source onto a small spot in a scanning location. A transport mechanism causes relative motion between a cell in the scanning location and the spot. A sensor generates a signal indicating the intensity of light emanating from the cell as a result of illumination by the light source. The system repeatedly takes readings of the light intensity signal and characterizes the light intensity along a substantially linear path across the cell. |
