AI continues to amaze – ChatGPT is now passing Wharton Business School exams, Microsoft and Google are doubling down in their AI efforts – and I’m as big a fan as anyone, but I want to talk about a technology that has been more under the radar, so to speak: ultrasound.
Yes, ultrasound. Most of us have probably had an ultrasound at some point (especially if you’ve been pregnant) and Dr. Eric Topol continues his years-long quest to replace the ancient stethoscope technology with ultrasound, but if you think ultrasound is just another nifty tool in the imaging toolbox, you’ve missed a lot.
Let’s start with the coolest use I’ve seen: ultrasound can be used for 3D printing. Inside the body.
This news on this dates back to last April, when researchers from Concordia University published their findings in Nature (I found out about it last week). Instead of the more common “Additive Manufacturing” (AM) approach to 3D printing, these researchers use Direct Sound Printing (DSP).
The paper summarizes their results: “To show unique future potentials of DSP, applications such as RDP [Remote Distance Printing] for inside body bioprinting and direct nanoparticle synthesizing and pattering by DSP for integrating localized surface plasmon resonance with microfluidics chip are experimentally demonstrated.”Continue reading…
