Glenn Herman: A Legacy in Computerized Tomography and Medical Imaging
The field of medical imaging has been profoundly shaped by the intersection of computer science and radiology. Among the key figures in this evolution is Glenn Herman, whose academic career spanned several decades and multiple prestigious institutions, focusing on the mathematical and technical foundations of how we visualize the internal structures of the human body.
Academic Foundations and Early Career
Herman began his professional academic journey in 1969 at the State University of New York (SUNY) at Buffalo. Joining the department of computer science as an assistant professor, he rose quickly through the academic ranks, becoming an associate professor in 1970 and achieving the rank of full professor by 1974.
A pivotal moment in his early career occurred in 1976 when he established the Medical Image Processing Group, a dedicated effort to advance the way digital tools are used to analyze medical data. This period of research culminated in 1980 with the publication of the first edition of his influential textbook, Reconstruction from Projections, which focused on the mechanics of computerized tomography (CT)—a process that uses X-rays to create cross-sectional images of the body.

In 1981, Herman transitioned his Medical Image Processing Group to the University of Pennsylvania. For nearly two decades, from 1981 to 2000, he served as a professor within the radiology department, bridging the gap between theoretical computer science and clinical application.
His contributions during this era earned him significant professional recognition. In 1991, he was elected as a fellow of the IEEE (Institute of Electrical and Electronics Engineers) for his work in the theory and development of techniques used to reconstruct and display computed tomographic images. Later, in 1997, he was elected a fellow of the American Institute for Medical and Biological Engineering. This honor recognized his efforts in implementing and evaluating methods for the 3D display of human organs using either transmitted or emitted radiation.
Final Tenure and Lasting Contributions
The final chapter of Herman's academic career took place at the City University of New York (CUNY). Joining the faculty in 2001, he served as a Distinguished Professor in the department of computer science until his retirement in 2017.
To keep the scientific community updated on the evolving nature of the field, Herman published a second edition of his seminal textbook in 2009. Retitled Fundamentals of Computerized Tomography, the work continues to serve as a foundational resource for those studying the reconstruction of medical images.

Frequently Asked Questions
What is computerized tomography?
Computerized tomography, or CT, is a medical imaging technique that uses computer-processed projections (typically X-rays) to reconstruct cross-sectional images of the internal organs and structures of the body.
What was the title of Glenn Herman's first textbook?
His first textbook, published in 1980, was titled Reconstruction from Projections.
Which professional organizations recognized Herman as a Fellow?
Herman was elected as a fellow of the IEEE in 1991 and a fellow of the American Institute for Medical and Biological Engineering in 1997.
Where did Glenn Herman spend the final years of his career?
He spent the final years of his career at the City University of New York (CUNY), where he was a Distinguished Professor in the department of computer science until 2017.
What specific contributions did Herman make to 3D imaging?
He developed, implemented, and evaluated methods for the 3D display of human organs based on the use of emitted or transmitted radiation.
