Invented by Ronald Nutt
and Mike Casey, the block detector has made possible the development of the high resolution tomograph that has slowed the cost of the PET scanner [and made it more affordable to the clinical sector] by decreasing the number of optical detectors needed.
Featured in Time magazine that year as â€œInvention of the Year, the PET/CT scanner was introduced as the fusion of a state-of-the-art PET scanner and a fast, multidetector spiral CT scanner as the brainchild of David Townsend, a physicist at the University of Geneva in Switzerland, and Ronald Nutt, electrical engineer and co-founder of CTI.
Unlike those earlier attempts, Townsend and Nutt
managed to create computer software that was able to control the two different imaging systems from one computer console.
