“…The usability and efficiency of the pathologists' workstation is likely to be a significant contributor. Our group has spent seven years studying the role of digital pathology in the efficiency of reading slides, beginning with work to confirm the suspected inefficiency of the systems [9], through detailed qualitative and quantitative studies of how pathologists work [14,19], to the pathologist-centred design and evaluation of a novel digital pathology workstation [13]. This paper reports the evaluation of the latest result of that work.…”

Summary:Digital pathology promises a number of benefits in efficiency in surgical pathology, yet the longer time required to review a virtual slide than a glass slide currently represents a significant barrier to the routine use of digital pathology. We aimed to create a novel workstation that enables pathologists to view a case as quickly as on the conventional microscope. The Leeds Virtual Microscope (LVM) was evaluated using a mixed factorial experimental design. Twelve consultant pathologists took part, each viewing one long cancer case (12-25 slides) on the LVM and one on a conventional microscope. Total time taken and diagnostic confidence were similar for the microscope and LVM, as was the mean slide viewing time. On the LVM, participants spent a significantly greater proportion of the total task time viewing slides and revisited slides more often. The unique design of the LVM, enabling real time rendering of virtual slides while providing users with a quick and intuitive way to navigate within and between slides, makes use of digital pathology in routine practice a realistic possibility. With further practice with the system, diagnostic efficiency on the LVM is likely to increase yet more.3

“…Glass microscope slides can be digitally scanned to show the cellular detail that is necessary for diagnosis, but the resulting images are extremely large (up to 180,000 × 100,000 pixels for standard-sized (75 × 25 mm) glass that is scanned at 400× magnification). The process is high-volume (in our region's cancer centre the 39 consultants inspect 250,000 slides per year 7 ) and virtual slides have the potential to make it more efficient by streamlining workflows and avoiding the need to physically transport glass slides to another hospital to obtain specialist second opinions 8,9 . However, one show-stopper that currently prevents histopathology from 'going digital' is that histopathologists take substantially longer to make a diagnosis from a virtual slide than with a glass slide 10 .…”

Large, high-resolution displays (LHRDs) allow orders of magnitude more data to be visualized at a time than ordinary computer displays. Previous research is inconclusive about the circumstances under which LHRDs are beneficial and lacks behavioural data to explain inconsistencies in the findings. We conducted an experiment in which participants searched maps for densely or sparsely distributed targets, using 2 million pixel (0.4m × 0.3m), 12 million pixel (1.3m × 0.7m) and 54 million pixel displays (3.0m × 1.3m). Display resolution did not affect the speed at which dense targets were found, but participants found sparse targets in easily identifiable regions of interest 30% faster with the 54-million pixel display than with the other displays. This was because of the speed advantage conferred by physical navigation and the fact that the whole dataset fitted onto the 54-million pixel display. Contrary to expectations, participants found targets at a similar speed and interacted in a similar manner (mostly short panning movements) with the 2-and 12-million pixel displays even though the latter provided more opportunity for physical navigation, though this may have been because panning used velocity-based control. We are applying these findings to the design of a virtual microscope for the diagnosis of diseases such as cancer.

“…In order to optimize the reading environment it is important to understand what the reading process and workflow consists of [ 64 , 65 , 66 , 67 , 68 ]. For example, Randell et al [ 66 ] studied four gastrointestinal histopathologists regarding the range of activities engaged in when viewing slides to determine how to best set up a digital viewing environment.…”

Human Factors and Human-Computer Considerations in Teleradiology and Telepathology

Radiology and pathology are unique among other clinical specialties that incorporate telemedicine technologies into clinical practice, as, for the most part in traditional practice, there are few or no direct patient encounters. The majority of teleradiology and telepathology involves viewing images, which is exactly what occurs without the “tele” component. The images used are generally quite large, require dedicated displays and software for viewing, and present challenges to the clinician who must navigate through the presented data to render a diagnostic decision or interpretation. This digital viewing environment is very different from the more traditional reading environment (i.e., film and microscopy), necessitating a new look at how to optimize reading environments and address human factors issues. This paper will review some of the key components that need to be optimized for effective and efficient practice of teleradiology and telepathology using traditional workstations as well as some of the newer mobile viewing applications.
