Customer Story: Henry Ford Health Services
Remote Diagnostic Ultrasound Imaging
Henry Ford Health Services uses Mediphan DistanceDoc™ and MedRecorder™ products in a variety of settings. The organization is at the leading edge of remote diagnostic research, pioneering programs such as remote-guided ultrasound diagnosis of the health of astronauts in the International Space Station. In its work with astronauts on ISS, the center quickly ran up against image quality and bandwidth challenges that made meaningful medical diagnosis difficult to impossible in such remote settings.
“To get ultrasound images from the space station to Earth, we were convolving the ultrasound signal into an S-video signal, then compressing it to downlink to a diagnostician headquartered in Houston,” explains Jack Butler, IT program manager in the Department of Surgery at Henry Ford.
In fact, that is the very barrier that other attempts at remote medical diagnostics have encountered: it is nearly impossible to obtain diagnostic-quality images due to multiple layers of image degradation that occurs during the capture and transmission of the data, either to storage devices or over networks. What the center needed in its remote-guided ultrasound research was an ultrasound imaging innovation—a breakthrough that it has found with Mediphan’s products.
Diagnostic-Quality Image Transmission
The center recently joined forces with GE, which is providing a number of its portable ultrasound machines—called GE LOGIQ Books—in support of a project being conducted with the Olympic Training Facility in Colorado Springs and Lake Placid. Butler, for his part, was tasked with finding a way to transmit both still and moving ultrasound images from the LOGIQ Books to the diagnosticians.
When he showed the research team the video converter equipment that had been used to accomplish a similar goal on the space station, it was generally agreed that it was far too complicated a solution to use on Earth. It was also too cumbersome to pack around with sports teams the hospital is responsible for, and required too much expertise to setup and use.
“We didn't want to have to send a radiologist to the site,” Butler explains. The point was to be able to provide rapid medical diagnosis of sports injuries even when a team of doctors was not onsite. “We wanted to be able to have someone onsite with minimal training to conduct the examination under the guidance of the remote expert back at the hospital, download the images and then let a radiologist do the analysis back home.”
Using Mediphan’s VGA broadcasting solution, DistanceDoc and the accompanying archiving product, MedRecorder, the research team can now conduct realtime remote expert guidance of the ultrasound examination and download and transmit “diagnostic-quality images and video sequences to experts almost as fast. We can now get exactly the same image that you see on the ultrasound machine to an expert at the other end; everyone is just amazed at how good the images look.”
Dr. Scott Dulchavsky, Chairman, Department of Surgery at Henry Ford, adds, “While still in these early stages of our research, the Mediphan system has been used by doctors to successfully remotely diagnose injuries to skaters and wrestlers. This is a huge step forward for our research, for GE and for the Olympic sports team.”
Opening Doors to New Applications
The diagnostic-quality images that DistanceDoc captures include muscular-skeletal images (bones and joints), as well as soft tissue scans (organs, blood flow, corneas, etc.). “What we are proving is that medical diagnosis can be done from these images—there is now no doubt about this,” Butler says. “The images are exactly what a diagnostician needs to see to make diagnosis and recommendations in the heat of battle, during a game, or for astronauts in space.”
Together, Mediphan and physicians at Henry Ford Health Services are now working together to expand the applications of the solution. “There are so many ways to expand this technology and move it forward, now that we have diagnostic-quality images. We're in a whole different ballpark now,” Butler says. “S-video images are not even a consideration for us now—we're playing a whole new game now.”
It brings the center a big step closer to its overriding mandate to apply its research to as broad a population as possible, including in underserved regions. “Our vision is that one day we'll be able to send out a kid on a bike with a portable ultrasound machine to scan the population of an entire village,” Butler says, “allowing us to determine exactly who needs to see a doctor. Thanks to DistanceDoc and GE's portable ultrasound technology, that vision looks all the more achievable today.”
