A Groundbreaking Glimpse into the Brain Through X-rays: Celebrating 50 Years
X-rays of the brain in thin cross sections — Science News, September 1, 1973
A new [device], already hailed by some physicians as the most important advance in X-ray diagnosis since its original development, promises to give a detailed new look at the inner brain.… The EMI device produces detailed information about a particular region of the brain with relatively little radiation exposure.
That device was the first X-ray computed tomography, or CT, scanner. Today, the technology lets doctors and researchers peer inside not only the human brain, but also other organs, bones and even blood vessels. CT scanning has also become a useful tool in other areas of science, from archaeology to zoology (SN: 12/18/21 & 1/1/22, p. 44). For instance, the technology helped reveal why pumpkin toadlets are clumsy hoppers: Their inner ears may be too small to maintain good balance (SN: 7/16/22 & 7/30/22, p. 5). Sharper images made by a “photon-counting” CT scanner — approved last year by the U.S. Food and Drug Administration — could help resolve other mysteries too.
