Abstract
Various embodiments provide an apparatus for analyzing natural killer (NK) cell activity using a lens-free shadow imaging technique and a method therefor. The apparatus for analyzing NK cell activity according to various embodiments has a dedicated algorithm configured to analyze the activity of NK cells on the basis of a lens-free shadow image of the NK cells. According to various embodiments, the dedicated algorithm detects at least one shadow parameter from at least a partial region of the lens-free shadow image, and uses the shadow parameter to analyze the activity of the NK cells. The shadow parameters include at least one of the peak-to-peak distances (PPD) indicating the distances between peaks in the region, the width of secondary maxima (WSM) indicating the width of the maximum brightness in the region, the standard deviation of the WSM (WSM_SD) indicating the standard deviation of the WSM, or the minima of the WSM (WSM_Min) indicating the minimum value of the WSM.
