There are a number of technologies to scan through human body but the best is still to come. A technique called Photoacoustic imaging can lead to the production of instant 3D images which can be used for diagnosing a host of diseases such as atherosclerosis and cancer. Stanford researchers are undertaking research to develop Photoacoustic imaging as a safe and multipurpose technique.
Khuri-Yakub at Stanford stated:
In diagnostic imaging you want to detect the smallest, earliest, most minimal presence of a disease at a site in the body. That’s really the motivation for wanting to optimize these technologies.
Photoacoustic imaging produces high resolution clear images and reaches the skin as deep as three centimeters. It is also an inexpensive technique. Under this technique infrared laser light is reflected on the area and tissues get heated up and this leads to the production of shockwaves which are picked up by detectors and the signals are transmitted to the computer which produces images depending upon the sound emitted. This technology is expected to change the world of imaging.
