Researchers 3D print unique micro-scale fluid channels used for medical testing

In a groundbreaking new study, researchers at the University of Minnesota, in collaboration with the U.S. Army Combat Capabilities Development Command Soldier Center, have 3D printed unique fluid channels at the micron scale that could automate production of diagnostics, sensors, and assays used for a variety of medical tests and other applications.

Tiny ultrasound detector achieves super-resolution imaging

A device described as the world’s smallest ultrasound detector has been created by Vasilis Ntziachristos and colleagues at the Technical University of Munich and Helmholtz Zentrum München. The extremely sensitive device can image structures smaller than individual living cells and is made using inexpensive and readily available silicon-on-insulator technology. With further optimization, the team says their detector could be mass-produced for use in a broad range of imaging applications.

Medical algorithms used in medicine are trained on data from only a few states

Most medical algorithms were developed using information from people treated in Massachusetts, California, or New York, according to a new study. Those three states dominate patient data — and 34 other states were simply not represented at all, according to the research published this week in the Journal of the American Medical Association.

Ultrasound signals are converted directly to visible images by new device

The first ultrasound imaging device that converts acoustic signals directly into light has been created by Hyeonggeun Yu and colleagues at North Carolina State University in the US.  The device was fabricated by depositing an organic LED onto a piezoelectric crystal and it can produce real-time images without the need for signal processing.
