'Deep patient' may point the way to better care

SAN JOSE, CA - With so much research focused on disease diagnosis using artificial intelligence, it's easy to overlook a largely untapped resource that could wield at least as much firepower to reinvent healthcare for the better. That resource is the deep patient, according to a May 11 talk at the NVIDIA GPU Technology Conference.

Photon-counting breast CT shows promise

Tests of a prototype photon-counting detector breast CT scanner show that the system could be useful as an adjunct to low-dose breast CT by separating the energy levels of different types of materials within the breast to assess tissue composition and improve cancer diagnosis.
