“…In particular, the issue of fraudulent digital image manipulation has emerged as a particular area of concern [6,12,24,25]. Critics of digital imaging claim that any image manipulation, willingly or unknowingly, alters digital data which causes a misrepresentation of the original information [26].…”

BackgroundThe purpose of this study was to assess the current usage, utilization and future direction of digital photography of gross surgical specimens in pathology laboratories across Canada.MethodsAn online survey consisting of 23 multiple choice and free-text questions regarding gross digital photography was sent out to via email to laboratory staff across Canada involved in gross dissection of surgical specimens.ResultsSixty surveys were returned with representation from most of the provinces. Results showed that gross digital photography is utilized at most institutions (90.0%) and the primary users of the technology are Pathologists (88.0%), Pathologists’ Assistants (54.0%) and Pathology residents (50.0%). Most respondents felt that there is a definite need for routine digital imaging of gross surgical specimens in their practice (80.0%). The top two applications for gross digital photography are for documentation of interesting/ complex cases (98.0%) and for teaching purposes (84.0%). The main limitations identified by the survey group are storage space (42.5%) and security issues (40.0%). Respondents indicated that future applications of gross digital photography mostly include teaching (96.6%), presentation at tumour boards/ clinical rounds (89.8%), medico-legal documentation (72.9%) and usage for consultation purposes (69.5%).ConclusionsThe results of this survey indicate that pathology staff across Canada currently utilizes gross digital images for regular documentation and educational reasons. They also show that the technology will be needed for future applications in teaching, consultation and medico-legal purposes.

“…One additional but unrelated legal consideration arises from the practice of image data manipulation for publication purposes. 6 The potential for scientific fraud is self evident and may increase with technological advancement. Current guidance suggests that retention of the original captured digital image data file is essential, together with a clear explanation of any subsequent manipulation.…”

Aims:To undertake a large scale survey of histopathologists in the UK to determine the current infrastructure, training, and attitudes to digital pathology.Methods:A postal questionnaire was sent to 500 consultant histopathologists randomly selected from the membership of the Royal College of Pathologists in the UK.Results:There was a response rate of 47%. Sixty four per cent of respondents had a digital camera mounted on their microscope, but only 12% had any sort of telepathology equipment. Thirty per cent used digital images in electronic presentations at meetings at least once a year and only 24% had ever used telepathology in a diagnostic situation. Fifty nine per cent had received no training in digital imaging. Fifty eight per cent felt that the medicolegal implications of duty of care were a barrier to its use. A large proportion of pathologists (69%) were interested in using video conferencing for remote attendance at multidisciplinary team meetings.Conclusions:There is a reasonable level of equipment and communications infrastructure among histopathologists in the UK but a very low level of training. There is resistance to the use of telepathology in the diagnostic context but enthusiasm for the use of video conferencing in multidisciplinary team meetings.

“…Rather than focus on the exaggerated perils of digital images, 9 histopathologists and other microscopy users should be examining the potential benefits of digital imaging to their work practice. We have described one example of the versatility of working with microscopy images in the digital medium.…”

Background: Many digital microscopy images suffer from poor illumination at the peripheries (vignetting), often attributable to factors related to the light path between the camera and the microscope. A commonly used method for correcting this has been to use the illumination of an empty field as a correction filter (white shading correction). Aims: To develop an alternative shading correction method that does not require this additional image. Methods/Results: This report outlines an alternative shading correction method that is based upon the intrinsic properties of the image, which are revealed through Gaussian smoothing. The technique can be implemented within Adobe Photoshop or other graphics editing software and works well with both haematoxylin and eosin and immunohistochemical images. Conclusions:This technique provides an effective means of optimising digital microscopy image appearances for printing, image analysis, or telepathology.
