Novel teleradiology system allows simultaneous collaboration


University researchers have devised a unique 3D teleradiology viewer that allows remote radiologists to collaborate simultaneously using the same image.

University researchers have devised a unique 3D teleradiology viewer that allows remote radiologists to collaborate simultaneously using the same image.

"This technology provides sophisticated image analysis features, enabling seamless collaboration across remote locations without any proprietary hardware and software," said medical imaging expert Vipin Chaudhary, Ph.D., an associate professor of computer science and engineering at the University at Buffalo.

Unlike other teleradiology solutions, Dynamic Medical Viewer allows multiple radiologists to collaborate on a case simultaneously from different remote locations. Everyone can look at the same 3D image at the same time, pointing out regions of interest and making annotations, he said.

Other teleradiology products available tend merely to retrieve images from a PACS, then transmit the studies somewhere so radiologists can read them, according to Chaudhary.

"What this system enables is the capability for radiologists in various locations to actually collaborate while doing the readings," he said.

The system works on any type of computer, whether desktop, laptop, or handheld, Chaudhary said. That's possible because the system is designed around a thin-client architecture, meaning remote radiologists who receive the studies are not required to have the massive computing power necessary to manipulate 3D images.

"Since we offload most of the 3D computing to the server side, we can do 3D image analysis extremely fast," he said.

The radiology world is moving more and more toward 3D imaging, and industry needs to get to the next level of PACS, where it provides more than data storage and retrieval services, Chaudhary said.

"First-generation PACS are fairly old now," Chaudhary said. "They serve merely as data repositories. The migration toward next-generation PACS, where you will have huge amounts of computing services attached directly to the PACS, is where the industry is moving. I think our development is in that direction."

A U.S. patent application on the technology is pending. The system has been licensed to a Buffalo firm called Medcotek, one of several companies located in the university's Center for Excellence that are either collaborating with or were founded by university researchers.

The company plans to launch the system later this year, according to chief financial officer Robert M. States.
