The scintiscanner was the first instrument used to create images for the detection of radioactivity within the body. It was invented in 1949 by Benedict Cassen and would tap to create dots in a paper; later improved in 1956 by Dr. David Kuhl where the paper was replaced by a radioisotope emission glow lamp (photorecorder) that produced images ...

In 1961, James Robertson and his associates at Brookhaven National Laboratory built the first single-plane PET scan, nicknamed the "head-shrinker." [ 84 ] One of the factors most responsible for the acceptance of positron imaging was the development of radiopharmaceuticals.

Currently, the first total-body PET scanner, the EXPLORER, is being built, which is 2 m in axial length and contains 560,000 individual detector elements, 2 some 10 times those in commercial scanners.

The first PET camera was built for human studies by Edward Hoffman, Michael M. Ter-Pogossian, and Michael E. Phelps in 1973 at Washington University, with DOE and NIH support. Phelps, who is often credited with inventing PET, received the 1998 Enrico Fermi Presidential Award for …

Dec 21, 2017 · On a peaceful afternoon in early summer 1977, the laboratory of CERN radiobiologist Marilena Bianchi was visited by a physicist with a pretty unusual request. He asked for her help in his quest to create a first image of a mouse using a PET (positron-emission tomography) camera.

PET is a nuclear medicine procedure which takes advantage of the unique signal produced by the annihilation of a positron and an electron yielding two photons of 511 ke V traveling in nearly opposite directions.

The first prototype PET/CT scanner thus became operational in 1998, designed and built by CTI PET Systems in Knoxville, TN (now Siemens Molecular Imaging) and subsequently clinically evaluated at the University of Pittsburgh.

The first PET scanners had a small number of radiation sensors to build the image, and they could do only a slice at a time. The slices were also very thick. Thus, the images obtained with the PET had a low quality and definition.

Jul 1, 1998 · The development of positron emission tomography (PET) illustrates how advances in basic science translates into benefits for human beings. In 1930 Ernest Lawrence and co-workers conceived of the cyclotron. By 1938 Lawrence, Livingston, et al …

Jan 1, 2002 · This was the first commercial PET scanner and it provided a means for the establishment of worldwide PET research programs. The first ECAT was delivered to University of California, Los Angeles, (UCLA) in 1976 with the arrival of Phelps and Hoffman at UCLA.
