Overview
The SOPTOP FS Series is a CE-compliant, high-throughput digital pathology scanner engineered specifically for automated microscopic screening of acid-fast bacilli (AFB) in sputum smear preparations. It operates on a brightfield optical imaging principle, integrating motorized XYZ-stage precision movement, high-resolution monochrome CMOS imaging (≥5.0 MP effective resolution at 40× objective), and real-time autofocus algorithms to capture standardized, focus-stacked whole-slide images (WSI) of Ziehl–Neelsen or fluorescently stained smears. Designed for TB-endemic clinical microbiology laboratories and public health reference labs, the system eliminates manual slide-by-slide visual scanning—a process historically prone to inter-observer variability and fatigue-related false negatives—by replacing it with reproducible, audit-ready digital acquisition and AI-assisted detection. The FS platform conforms to ISO 15189 requirements for pre-analytical standardization and supports traceable digital workflows aligned with WHO’s End TB Strategy diagnostic acceleration goals.
Key Features
- Automated Whole-Slide Scanning: Fully motorized stage with programmable scan path optimization; supports batch processing of up to 200 slides per unattended run (FS-200 variant) or 50 slides (FS-50 variant).
- Intelligent Slide Pre-Inspection: Integrated wide-field preview camera generates low-magnification overview images, automatically detecting smear boundaries, optimal scanning regions, and initial focal plane distribution.
- Barcode & Label Recognition: OCR-compatible slide label reading (ISO/IEC 15415 compliant) ensures accurate specimen-to-image association and bidirectional LIS/HIS linkage.
- Adaptive Autofocus System: Multi-point contrast-based autofocus with dynamic refocusing during scanning to maintain optical fidelity across uneven smear topography.
- Configurable Scan Protocols: User-defined parameter groups—including magnification (20×/40×), exposure time, white balance, and z-stack depth—enabling method-specific SOP compliance.
- Targeted Review Interface: Ambiguous detections are spatially mapped and presented as navigable ROI thumbnails within the review workstation, allowing rapid optical verification under conventional microscope integration mode.
Sample Compatibility & Compliance
The FS scanner accepts standard 26 mm × 76 mm glass slides with thicknesses from 0.9 mm to 1.2 mm. It accommodates both conventional Ziehl–Neelsen–stained smears and auramine-rhodamine fluorescent preparations. All image acquisition parameters adhere to the College of American Pathologists (CAP) Digital Pathology Checklist v2.0 for WSI validation. The system meets IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards. Software architecture supports audit trail logging per FDA 21 CFR Part 11 requirements when deployed in GLP/GMP-regulated environments. Data export formats include DICOM-SR (Structured Reporting), SVS, and TIFF with embedded EXIF metadata.
Software & Data Management
The proprietary SOPTOP PathScan™ software suite provides integrated acquisition, AI inference, review, and reporting modules. Its deep learning engine (trained on >120,000 annotated AFB-positive/negative fields from multi-center clinical datasets) performs pixel-level segmentation and classification with sensitivity ≥94.2% and specificity ≥91.7% (validated against consensus expert microscopy). All analysis logs—including user login events, ROI annotations, result modifications, and timestamped decision trails—are immutably stored. Native DICOM connectivity enables seamless integration with PACS, LIS, and HIS via HL7 v2.5.3 and DICOMweb RESTful APIs. Encrypted local storage (AES-256) and optional TLS 1.3-enabled cloud sync ensure data sovereignty and HIPAA-aligned transmission security.
Applications
- Routine TB case screening in district hospitals and national TB control programs
- Quality assurance and proficiency testing for microscopy centers
- Training support for laboratory technologists via annotated digital slide libraries
- Longitudinal monitoring of smear conversion during anti-TB therapy
- Multi-site epidemiological studies requiring standardized digital morphology archives
FAQ
Does the FS scanner require external calibration or daily maintenance?
No routine optical recalibration is required; the system performs self-diagnostic checks at startup and includes automated dust detection with alert-triggered cleaning prompts. Preventive maintenance is recommended annually per ISO 13485 service protocols.
Can the AI detection model be retrained with institution-specific data?
Yes—SOPTOP provides a validated model retraining toolkit under NDA, supporting transfer learning with locally acquired, IRB-approved datasets while preserving original regulatory clearance scope.
Is remote technical support available outside China?
Yes—24/7 remote diagnostics and firmware updates are delivered via secure VPN tunnel; on-site engineering support is available through authorized regional partners in Southeast Asia, Africa, and Latin America.
What DICOM conformance profiles does the system implement?
It supports DICOM PS3.12 (Media Storage Application Profiles) for CD/DVD archival and PS3.18 (Web Access to DICOM Persistent Objects) for browser-based review, certified to IHE Digital Pathology Technical Framework (2023 Edition).
