Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 10:
11. A non-transitory computer readable medium having stored thereon one or more sequences of instructions for causing one or more processors to:
move a scanning stage in a controlled direction relative to an imaging system;
digitize, via the imaging system, a portion of a sample supported by the scanning stage during the movement of the scanning stage in the controlled direction, the imaging system configured to scan the sample as a plurality of lines based on movement of the sample in the controlled direction, each of the plurality of lines overlapping with its adjacent line, wherein the imaging system is configured to combine the scanned lines into a whole slide image;
control movement of the scanning stage in the controlled direction;
generate, using one or more hardware position encoders, sensor data during the movement of the scanning stage in the controlled direction;
detect movement of the scanning stage in the controlled direction and in a direction that is different from the controlled direction;
determine if a duration of the detected movement exceeds a predetermined duration threshold;
determine if a distance of the detected movement exceeds a predetermined distance threshold, wherein the predetermined duration and distance thresholds are determined based on detecting a vibration-induced drift in the movement of the scanning stage that causes one or more adjacent lines of the plurality of lines to not overlap and frustrates the ability of the imaging system to combine the lines into the whole slide image; and
in response to determining that the detected movement exceeds the one or more of the predetermined duration and distance thresholds, initiate a re-digitizing of the portion of the sample corresponding to the one or more adjacent lines of the plurality of lines that do not overlap.
