Fig. 1: Architecture of the Multi-Camera Array Scanner (MCAS).

a The MCAS with 6 × 8 sensor array (48 × 13-megapixel CMOS sensors and associated objective lenses). b Rapid 3D imaging with 48 compact microscopes, each providing a distinct 1.5 mm field of view. 7 × 7 lateral scanning grid addresses the 9 mm inter-camera gaps and axial scanning captures surface irregularities of thick specimens. c Simultaneous digitization of 3 thick cytology smears with MCAS produces high-resolution stitched image from 2352 unique captures. d High-speed focus adjustment capabilities enable 3D slide examination. e The MCAS can facilitate efficient cytopathology consultations with rapid 3D whole slide imaging and integrating machine learning capabilities.
