Sensor-Based Technique for Manually Scanned Hand-Held Optical Coherence Tomography Imaging

Figure 4

OCT B-scans of in vivo human cheek skin acquired using the manually scanned imaging probe. (a) B-scan obtained without sensor feedback. Smearing artifacts are marked by dashed yellow rectangles. (b) B-scan obtained with sensor feedback showing the absence of imaging artifacts. Red arrows indicate regions of low scattering, which correspond to sebaceous follicle infundibuli.
