Health Canada approved iPhone/iPad app for stroke diagnosis

CTV News has done a great report where you can see the app in action.

“”In a medical emergency, medical imaging plays a critical role in diagnosis and treatment, time is critical in acute stroke care, every minute counts.” said Dr. Mitchell who is from the University of Calgary’s Faculty of Medicine.”

CBC also has a report that is worth a watch.

“”Now a physician anywhere can get a call on their iPhone and can immediately take a look at the images in the remote community,” said Ross Mitchell, a professor of radiology at the university who helped develop the software. “They can do more than just look at them. They can cut into them, rotate it in 3D, they can do all kinds of advanced visualizations and analysis, which may be critical to make the diagnosis.“”

Feels great to see some cutting edge tool developed in Calgary. From the University of Calgary, Faculty of Medicine press release,

“New research from the University of Calgary’s Faculty of Medicine shows that doctors can make a stroke diagnosis using an iPhone application with the same accuracy as a diagnosis at a medical computer workstation. This technology can be particularly useful in rural medical settings. This allows for real-time access to specialists such as neurologists, regardless of where the physicians and patients are located”

Here is the original JMIR (Journal of Medical Internet Research) technical paper, “A Smartphone Client-Server Teleradiology System for Primary Diagnosis of Acute Stroke“.

Discussion & Note

Not to take away from the significance and importance of team’s achievement, there are limitations in using the system over 3G network due to data transfer rate issues as indicated in the technical paper.

“The system should provide practical frame rates over cellular or wireless networks. In our experience, a single visualization server can accommodate 10 or more simultaneous iOS device users and is capable of delivering and displaying up to 14 frames per second on an iOS device connected over a 802.11g Wi-Fi network. The frame rate was enough to provide sufficient interactivity for comfortable use. However, the frame rate on a 3G cellular network was 1 to 4 frames per second, which was insufficient for practical use. We know that fourth generation (4G) cellular networks are now installed in many metropolitan centers. We estimate that the higher bandwidth of these new cellular networks should allow 10 to 15 frames per second to be delivered to smartphones. However, currently only the iPhone 4 and a few Android-based smartphones are capable of utilizing greater network bandwidth.”
