Biomedical entrepreneur Jonathan Rothberg is working to create a cheap, portable medical imaging device that will make the technology accessible by the general public, according to reporting in MIT Technology Review. Rothberg previous started and sold two DNA-sequencing companies.

The imaging system is being developed by Butterfly Network and funded with the $100 million raised by Rothberg. Though details are sparse  the device is expected to be “small, cost a few hundred dollars, connect to a phone, and be able to do things like diagnose breast cancer or visualize a fetus,” according to the article. Additional details will be available when it is closer to market; Rothberg predicts that will be “in the next 18 months.”
