A High-resolution Medical Imaging Camera Invented by Researchers at Northwestern University

Researchers at Northwestern University were in the news recently for the invention of the innovative high-res camera that can see otherwise tricky things. The camera can easily penetrate into minute details such as the corners, skin, or even the skull. 

Here is how the camera functions. First, coherent light is indirectly scattered into the hidden objects, which disassembles again for its travel back to a camera. Then, as the next step, an algorithm will be utilized to reconstruct the spread signal to reveal hidden features.

The study details are included in the Nov.17 journal Nature Communications. 

The method is ideal for non-invasive medical imaging. However, the possibilities are endless for this method. In fact, this innovative method is the first of its kind for imaging around the corners. Also, it is the first ever to do so through scattering media that includes high spatial and temporal resolution, a tiny probing area besides an angular field of view.

The medical imaging arena was buzzing with activities in the recent times. Medical experts carried out a lot of experiments to develop exact imaging technologies.

Over the years, several imaging techniques were invented. However, they typically had one or more than one problem: low resolution, microscopic angular field of regard, time-consuming raster scans, and so on. The innovative method is of interest to the medical imaging world as it successfully overcomes these issues.

“Our current sensor prototypes use visible or infrared light, but the principle is universal and could be extended to other wavelengths. For example, the same method could be applied to radio waves for space exploration or underwater acoustic imaging”, this is what Florian Willomitze, from Northwestern University, had to say about the new technology. Florian is the first author of the published study on this new technology.
