“Dr. Ledley is best known for developing the first whole-body computerized tomography (CT or CAT) scanner in 1973″
He called his invention the automatic computerized transverse axial scanner (ACTA). It was, in effect, the first machine capable of producing cross-sectional images of any part of the body.
” Dr. Ledley was inducted into the National Inventors Hall of Fame in 1990 and in 1997 received the National Medal of Technology. “
Dr. Ledley had more than 20 patents ….
The Story Behind the Development of the First Whole-body Computerized Tomography Scanner as Told by Robert S. Ledley
”
Dr. Robert S. Ledley is credited with “sowing the seeds” for the field of medical informatics [Ledley 1959], 1 initiating the development of computerized medical image analysis [Ledley 1964], 2 and for being the principal investigator of the Protein Information Resource (PIR) for 20 years [Dayhoff 1965] “https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1561796/

. In 1959, he wrote two influential articles in Science: “Reasoning Foundations of Medical Diagnosis” (with Lee B. Lusted) and “Digital Electronic Computers in Biomedical Science”. Both articles encouraged biomedical researchers and physicians to adopt computer technology. In 1960 he established the National Biomedical Research Foundation (NBRF), a non-profit research organization dedicated to promoting the use of computers and electronic equipment in biomedical research. https://en.wikipedia.org/wiki/Robert_Ledley
