12 JunRadiology… moves… so… slowly.
We’ve been using a programmable keypad and graphics tablet to annotate MRI brain anatomy for years. It’s nice to hear that Radiology is figuring out user interface issues: Denton, Kevin, Irfanullah Haider, Jacqueline Hill, Suzanne L. Hunt, and Ryan Ash. “Of Mice and Roentgen: Radiologist Satisfaction with a Non-conventional 13-Button Mouse—One Institution’s Experience.” Journal of digital […]

Interesting discussions about AI in healthcare at the World Medical Innovation Forum in Boston. There seems to be general agreement on this: “Artificial Intelligence is like teenage sex: everyone talks about it, nobody really knows how to do it, everyone thinks everyone else is doing it, so everyone claims they are doing it.” Don’t believe […]

There is a nice description of AI in medical imaging from Signify Research that concludes, “Access to radiologist annotated data remains a major challenge for many algorithm developers, who must be prepared to invest significant time and money in data curation. Companies with innovative strategies for obtaining data will have a big advantage.” Hey, that’s what we […]

“DeepMind Shows AI Has Trouble Seeing Homer Simpson’s Actions” (link), describes how machine learning (deep learning, neural networks, artificial intelligence) needs annotated data to train on so they went with Amazon’s Mechanical Turk service to create it. That works because we all have visual systems that to a great job. But some deep learning applications need expertise beyond what […]

C. Ledig and D. Rueckert, in Chapter 14 of this recent book, describe segmentation of MR brain images, and conclude: “The performance of current state-of-the-art techniques is starting to approach that of human observers in terms of accuracy. However, the robustness of current approaches is not yet comparable to human observers. This is especially true […]

This article from Science shows why a probabilistic atlas that includes left-handed individuals is important: Brain-zapping therapies might be hitting lefties on the wrong side of the head
