ABSTRACT:
A test checks for appropriate positioning of priority fields for image collection and evaluation. The tests characterize lateral repeatability of stage movement in an X-Y plane, the longitudinal repeatability of the stage along a Z axis, cross coupling of motion in the Z direction from the X-Y stage movement, repeatability of the microscope objective turret positioning, mechanical centration of optical paths and the parfocality of optical paths. The process includes moving to a rough location, performing focus pans to determine the best focus and searching for a known object to register coordinate locations, processing those locations to determine the repeatability and accuracy of the motion system. Further, a means of evaluating these parameters is disclosed by which an automated cytology instrument will validate or invalidate data taken since the last position integrity check.
