New Way to Look at Tissue Biopsies: Spatial Light Interference Microscopy


Pathologists would gain new tool to diagnose cancer faster and more accurately, based upon stain-free analysis of tissue
Reading tissue biopsies with a new stain-free method could eventually help pathologists achieve faster and less subjective cancer detection. Should this technology prove viable, it would also displace many of the longstanding tissue preparation methodologies used today in the histopathology laboratory.
Credit a research team from the Beckman Institute at the University of Illinois (UI) Christie Clinic and at the UI campuses in Urbana and Chicago, with developing this new technology.
They call the technique Spatial Light Interference Microscopy (SLIM). According to a story reported by Futurity.org, the technique uses two beams of light.
New Technology Could Help Pathologists Detect Cancer Earlier
In the Proceedings of the National Academy of Sciences, the scientists stated the new technology offers answers to some of the most elusive questions in contemporary biology: how cell growth is regulated and how cell size distributions are maintained. “SLIM can be so valuable for greatly improving the chances of early detection and treatment of cancer,” declared study leader Gabriel Popescu, Ph.D., Quantitative Light Imaging Laboratory, Department of Electrical and Computer Engineering at the Beckman Institute.
The reason for Popescu’s optimism is SLIM’s capabilities using optical interferometry, or interference patterns, to make accurate measurements of waves at the molecular level. This enables the technique to work with great sensitivity.

Pathology Labs Replace Microscopes with Digital Imaging


Non-US deployment of Aperio platform with image storage on a Hitachi platform.  400,000 glass slides annually at a rate of 300 TB of storage per year.  Very cool. Look for more adoption overseas this year.  
Microscopes are being replaced with digital imaging in pathology laboratories in the southern part of Sweden.

Traditional microscope glass slides are turned into digital images, which are then analyzed by pathologists directly from the computer screen, instead of using regular microscopes.

The revolution, which has already occurred in radiology, is now taking place in pathology. The contracted delivery not only digitizes the slides but also will completely renew IT support for all workflows of the pathology laboratories in the Skåne region.

Labvantage (Somerset, NJ, USA) will deliver a USD 4 million turnkey solution for digitizing the histopathological workflows in the whole region. The system will be possibly the largest such installation in the world and among the first of its kind in northern Europe. The digital slides will reside in Hitachi’s (Tokyo, Japan) Content Platform, which employs distributed object storage. All of the images will be kept well protected and duplicated across several physical discs. This makes the traditional backing up of data unnecessary.
