Computer Software and Digital Systems: Focus on Telepathology
Jaleh Mansouri, M.D.


Since Dr. Ronald Weinstein’s introduction of the term "telepathology" in the 1980's, advances in computer and digital technology have resulted in an increasing number of important applications of this modality including whole slide imaging (virtual microscopy), robotic microscopy, and remote diagnostic pathology consultation. Telepathology systems can exist in static, dynamic, or hybrid formats. Static systems transmit pre-scanned data (i.e. store-and forward) to remote locations for analysis. Dynamic systems transmit entire image data for analysis in real time. Static systems are cheaper, while the more expensive dynamic systems provide visual data with greater accuracy (resolution). Among the technical issues involved with employing telepathology systems are speed of transmission of large amounts of data over the Internet and standardization of transmitted image data (e.g. color correction).

With the expanding applications of telepathology, the preservation of confidentiality during the transmission of patient information has become an important issue. Various encryption software programs are available and employ public-key cryptography. More advanced telepathology software systems (e.g. Pixera, Apollo) have integrated encryption capabilities. Since telepathology systems can be quite expensive, it is important for pathology laboratories to closely examine their functional needs and budgetary constraints before the implementation of such a system.

Optronics provides Microcast® HD real-time High Definition Co-Observation, which replaces multi-head microscopes. The Optronics Microcast HD offers full 1080p HD digital co-observation from a microscope with 2MP progressive scan digital images at 60 FPS. The camera system uses 3CCD medical grade RGB imaging technology for precise real-time color reproduction of microscope images without interpolation. The camera's ultra high speed automatic camera shutter instantaneously compensates for higher magnification objectives and decreases in illumination. Optional full 1080p HD image capture of HD microscope images without a computer is available for reports and publications. Microcast HD eliminates the need for a multi-head microscope. For more information, please visit www.optronics.com.

Photodyne Technologies manufactures top of the line computerized macro photography systems for grossing, pathology, histology and other scientific applications, using high resolution digital cameras. Various models are available, and the company specializes in custom designs, usually at no extra charge. These state of the art macroscopic (gross) imaging units revolutionize the picture taking process in the laboratory. The systems enable even non-photographers to take professional quality photos in seconds. The patented, state-of-the-art systems are used by hundreds of leading hospitals, universities, medical examiner offices and research institutes worldwide. The included proprietary software allows one to take pictures directly from the computer. All attributes of the camera are controllable from the computer as well, and the image is viewable in real time on the screen, allowing adjustments before the picture is taken. The picture is then transferred directly to the computer and is stored on the computer's hard drive for editing, archiving, or email as an attachment like any other image file via the internet.
