For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early.

In a new paper, the team reports that it has improved the resolution of the images produced by its system, making it easier to spot potential tumors, as well as cysts and microcalcifications. The researchers also created a user interface that makes it simple to use the ultrasound probe, even for people with no expertise in ultrasonography.

This system, they believe, could not only enable earlier detection but also allow for long-term monitoring following breast cancer treatment—either in a doctor’s office or at home.
