Screening for Cervical Cancer Using Automated Analysis of PAP-Smears

Figure 4

Illustration schematically showing image scanning using one- or two-dimensional sensor arrays. With a 2D array an image or a stack of images at different focus levels are read before the microscope stage moves a few hundred micrometers to a new position where this process is repeated as soon as the vibrations caused by the move have died out. With a 1D array the microscope stage is moving continuously and single lines in the direction orthogonal to the move are read into the computer creating a continuous flow of image data.
