Digital Pathology Training for Biomedical Scientists: What You Need to Learn
Digital Pathology Training for Biomedical Scientists: What You Need to Learn
Digital pathology is transforming how histopathology laboratories operate across the NHS. By converting glass slides into high-resolution digital images, it enables remote reporting, AI-assisted analysis, and more efficient workflows. For biomedical scientists working in cellular pathology, understanding digital pathology is becoming essential rather than optional. This guide covers the training you need and how to build your career in this rapidly evolving field.
What Is Digital Pathology?
Digital pathology involves the use of whole slide imaging (WSI) technology to digitise tissue sections on glass slides. These digital images can then be viewed, analysed, and reported on using specialised software, either locally or remotely.
The technology encompasses several components:
- Whole slide scanners that capture images at 20x or 40x magnification
- Image management systems that store, organise, and distribute digital slides
- Viewing software that allows pathologists to navigate and annotate images
- AI and machine learning algorithms that can assist with tasks such as tumour detection, mitotic counting, and biomarker quantification
How It Is Changing Histopathology Labs
The adoption of digital pathology across the NHS has accelerated significantly since 2020. Several factors are driving this change:
- Pathologist workforce shortages: The Royal College of Pathologists has consistently highlighted consultant vacancies. Digital pathology enables remote reporting and cross-site collaboration, helping to address this gap.
- Faster turnaround times: Digital workflows can reduce the time from slide preparation to report, particularly when combined with AI triage.
- Standardisation: Digital images provide a permanent, shareable record that supports multidisciplinary team meetings, education, and quality assurance.
- Research integration: Digital slides can be used for retrospective studies and teaching without the limitations of physical slide archives.
Leading NHS Centres
Several NHS trusts have led the way in digital pathology implementation:
- Leeds Teaching Hospitals NHS Trust was one of the first trusts in the UK to achieve a fully digital primary diagnostic histopathology service
- Cambridge University Hospitals has integrated digital pathology with its genomics programme
- University College London Hospitals (UCLH) has pioneered AI-assisted diagnostics within a digital workflow
- The Christie NHS Foundation Trust in Manchester has adopted digital pathology for cancer diagnostics
The Role of BMS in Digital Pathology
Biomedical scientists are central to the digital pathology workflow. Your responsibilities may include:
Slide Scanning
Operating whole slide scanners requires understanding of focus settings, scan area selection, magnification requirements, and troubleshooting. Poor scan quality can render a digital slide unusable for diagnosis, so the BMS role in quality assurance at the scanning stage is critical.
Quality Checking
Every scanned image must be checked for quality before it reaches the reporting pathologist. This includes verifying focus, checking for artefacts, ensuring tissue is fully captured, and confirming that the digital image matches the correct patient and specimen.
Image Management
Managing the digital slide archive, ensuring images are correctly linked to the laboratory information management system (LIMS), and maintaining data integrity are all BMS responsibilities in a digital laboratory.
Equipment Maintenance
Scanners require regular maintenance, calibration, and performance monitoring. Biomedical scientists with an aptitude for IT and instrumentation are well-suited to these roles.
Training Requirements and Courses
IBMS CPD and Specialist Portfolios
The IBMS recognises digital pathology within its cellular pathology training framework. CPD activities related to digital pathology, including scanner operation, image analysis, and quality management, count towards your professional development requirements.
Royal College of Pathologists Resources
The RCPath has published guidelines on implementing digital pathology and offers educational resources through its events programme. Their recommendations on validation of digital pathology systems are essential reading for anyone involved in implementation.
University Courses
Several UK universities offer modules or short courses relevant to digital pathology:
- MSc Digital Pathology and related postgraduate programmes are emerging at institutions including the University of Leeds and University of Warwick
- Short courses on whole slide imaging, AI in pathology, and digital workflow management are available through various providers
- Online learning platforms increasingly offer modules on computational pathology and image analysis
Manufacturer Training
Scanner manufacturers such as Leica Biosystems (Aperio), Hamamatsu, Philips, and 3DHISTECH provide product-specific training. This is usually arranged through your laboratory when new equipment is installed.
Skills You Need to Develop
IT Literacy
Digital pathology requires a higher level of IT competence than traditional histopathology. You should be comfortable with:
- Network-connected instrumentation and data transfer
- Image file formats and storage requirements (digital slides can be several gigabytes each)
- Database management and system integration
- Basic troubleshooting of software and connectivity issues
Image Analysis
Understanding the principles of image analysis, including colour normalisation, tissue segmentation, and annotation, is increasingly valuable. While you may not be developing AI algorithms yourself, understanding how they work helps you contribute to validation studies and quality assurance.
Quality Management
Digital pathology introduces new quality considerations including scanner calibration, monitor specifications for diagnostic viewing, and data governance. Experience with ISO 15189 quality management principles provides a strong foundation.
Career Opportunities
Digital pathology is creating new roles and expanding existing ones:
- Digital Pathology Coordinator (typically Band 6-7, £37,338-£52,809): Manages the digital workflow, scanner operation, and image quality
