Imaging

X-ray vision has long been a superpower, but soon mere mortals could see hidden objects with help from AI. A new “ghost imaging” system reads the brainwaves of a person looking at light scattered off a wall to identify an object around a corner.
-
German engineer Gaurav Singh has designed and built an industrial USB box camera in a custom 3D-printed case that not only accepts interchangeable lenses, but the image sensor can also be swapped out as needed.
-
The world’s most powerful X-ray laser is ready for operation after a massive overhaul. The upgraded LCLS-II uses temperatures colder than deep space to accelerate electrons to near light-speed and fire off a million X-ray bursts per second.
-
An ongoing study is testing a new kind of neuroimaging device designed to easily capture brain activity in real-time. These experiments will investigate the effects of ketamine on functional connectivity in the brain before, during and after an experience.
-
Hundreds of scientists around the globe have shared data to create the world's first brain growth chart. The project incorporated MRI scans from subjects of all ages to offer a unique portrait of how our brains change over the course of a lifetime.
-
A new AI tool can accurately measure plaque deposits in arteries and predict a patient’s risk of suffering a heart attack within five years. The tool promises to achieve in seconds what has previously taken trained experts up to 30 minutes to deliver.
-
A new study has offered a unique insight into the effects of mild COVID-19 on the brain by investigating scans from people before and after viral infection. The research indicates the impact of COVID-19 on the brain is “significant” and “deleterious.”
-
A new type of radar can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects, and even monitor patient vital signs in hospitals.
-
When it comes to taking high-res aerial photographs, we generally look to satellites, drones or full-size aircraft. Colorado-based Urban Sky's new Microballoon system, however, is claimed to deliver higher-resolution images at a much lower cost.
-
MRI is a powerful diagnostic tool, but the size and cost limits where it can be used. A compact, affordable new MRI system uses a much smaller magnetic field and doesn’t require shielding, and is still able to diagnose brain disorders in patients.
-
Princeton and the University of Washington researchers have developed a camera the size of a grain of salt that can snap sharp, full-color images. It’s made with a metasurface that captures light and could be scaled up to turn entire surfaces into sensors.
-
Blind corners have long troubled drivers, but researchers have now developed a holographic camera technology that can peer around corners by reconstructing scattered light waves, quickly enough to spot fast-moving objects like cars or pedestrians.
