3D in Medical Imaging: What Care Providers Need to Know
By MedTech Outlook | Thursday, February 28, 2019
Medical imagery is used in a short period of time to create visual representations of the body’s interior for clinical analysis and medical intervention of complex diseases. As medical providers continue to seek innovative ways to improve patient care, the medical imaging market is growing significantly. In the last two years, 3D digital medical imaging systems have effectively doubled in size. The potential applications are endless as there is continuous progress in 3D displays, including glass-free 3D volumetric displays.
Through studies, researchers have found a way to improve security and expand the use of 3D x-ray imagery in a number of applications. Researchers at the Australian National University and a team at the European Synchrotron Radiation Facility (ESRF) in France have found a way to generate 3D images using x-rays. It improved disease screening, studied extremely rapid processes, and analyzed the properties of opaque objects' materials and structural information.
The researchers were able to create random x-ray patterns and take a 2D image by shining a bright beam of x-ray light via metal foam. A weak copy of the beam was then passed through the sample with a large single-pixel detector capturing the x-rays passing through samples. They repeated this process to build a 3D tomographic image of the internal structure of the object for multiple illuminating patterns and sample object orientations.
A second team, led by Marco Stampanoni from the Paul Scherrer Institute in Switzerland, together with a team from the DeutschesElektronen - Synchrotron (DESY) in Germany and the ESRF, used high - brilliance radiographic sources.
Using a single exposure produced at specialized synchrotron facilities, they have obtained 3D information from x-rays one hundred billion times brighter than a hospital X-ray source. Using the new technique, researchers can make the necessary measurements to form a 3D image before destroying the sample, which may be useful for delicate biological samples.
Medicine is one of the most rapidly changing industries in the world as innovation and technological advancements take place. The technology is poised to change the diagnostic methods and treat a plethora of medical scenarios. A picture is worth a thousand words, and a 3D image could save a life.
