A programmable microscopic stage: Design and development

Area of Science:

• Pathology
• Microscopy
• Automation Engineering

Background:

• Motorized microscopes facilitate slide imaging but require manual intervention for scanning patterns.
• Current methods can be time-consuming and may miss areas of the specimen.
• Human intervention during screening leads to delays and potential omissions.

Purpose of the Study:

• To develop a programmable framework for customized, automated microscope stage scanning.
• To eliminate human intervention during the complete screening process.
• To enhance the precision and efficiency of pathological slide examination.

Main Methods:

• Implementation of a programmable framework and firmware for microscopic stage control.
• User-defined scanning patterns using 2D graphics drawing primitives.
• Conversion of patterns into machine-readable codes via micro-computer numeric controlled software for precise stage movement using servo drives and motors.

Main Results:

• A cost-effective, portable system for automated, customized microscopic slide scanning was developed.
• The system reduces reliance on technicians for whole slide examination.
• Pre-defined scanning patterns were successfully tested and validated for stage movement accuracy.

Conclusions:

• The proposed system enables fully automated and customizable scanning of microscopic specimens.
• This automation improves efficiency, reduces errors, and increases accessibility in pathological studies.
• The system's portability allows integration with various microscope types, including conventional and fluorescence models.
