Online Lecture 2024 Milestones in CT: Past, Present, and Future Cynthia McCollough 7pm (GMT) on Friday 14th November by Zoom ... details below |
In 1971, the first patient CT exam by Ambrose and Hounsfield paved the way for not only volumetric imaging of the brain but of the entire body. From the initial 5-minute scan for a 180-degree rotation to today’s 0.24 second scan for a 360-degree rotation, CT technology continues to reinvent itself. This presentation will describe key historical milestones in CT technology from the earliest days of CT to the present, with a look toward the future of this essential imaging modality. After a review of the beginnings of CT and its early adoption, the technical steps taken to decrease scan times – both per image and per exam – will be reviewed. Novel geometries such as electron beam CT and dual-source CT have also been developed in the quest for ever faster scans and better in-plane temporal resolution. The focus of the past two decades on radiation dose optimization and management led to changes in how exposure parameters such as tube current and tube potential are prescribed such that today, exams are more customized to the specific patient and diagnostic task than ever before. In the mid-2000s, CT expanded its reach from greyscale to color with the clinical introduction of dual-energy CT. Today’s most recent technical innovation – photon counting CT – offers greater capabilities in multi-energy CT as well spatial resolution as good as 125 microns. Finally, artificial intelligence is poised to impact both the creation and processing of CT images, as well as automating many tasks to provide greater accuracy and reproducibility in quantitative applications.
A recognized leader in the development and evaluation of new CT technology and dose reduction methods, Cynthia H. McCollough, PhD, is the Brooks-Hollern Professor at the Mayo Clinic in Rochester, Minnesota, where she holds the rank of professor in both medical physics and biomedical engineering. Dr. McCollough is a fellow of the American College of Radiology, the American Association of Physicists in Medicine, and the American Institute for Medical and Biological Engineering. She has over 500 peer-reviewed papers and multiple NIH grants related to CT imaging. She has served as the president of the American Association of Physicists in Medicine and is a vice-president of the International Society of Computed Tomography. She received her master's and doctorate degrees in medical physics at the University of Wisconsin, Madison after graduating in physics from Hope College in Holland, Michigan. The first whole-body, high-flux photon counting CT (PCCT) was installed in her lab in 2014 and she has played a key role in the development of PCCT since then. She has a particular interest in the history of CT imaging.

JOHN CLIFTON ESSAY PRIZE |
About the prize
The British Society for the History of Radiology is pleased to invite entries for the John Clifton Essay Prize, an initiative to promote research and insight into the history of radiological sciences (including medical imaging, radiotherapy & nuclear medicine).
We are keen to receive essays that explore all aspects of radiology history including scientific discovery and technological development; biographical accounts; societal impact and cultural dimensions. Essays which explore less well-known events / figures, or which demonstrate the relevance of historical events to current and future practice are encouraged. Topics may include diagnostic imaging, interventional techniques, radiotherapy and may seek to highlight the work of radiologists, radiographers, physicists and engineers, or may explore imaging and therapeutic techniques from the patient’s perspective. Whilst entries are open to all, we particularly welcome participation from healthcare professionals in training and from undergraduates. Essays should be based on accurate historical research, but personal insights, reflections and perspectives can be included.
The prize is named in honour of Professor John Clifton, renowned medical physicist and member of BSHR, who sadly died in 2023.
Competition details
Closing date: Friday 25 October 2024( Note that the closing date has been extended)
Word limit: 5000
Essays should be submitted in Word.
Essays should be fully referenced.
If images are included, it should be possible to determine the copyright status to facilitate potential publication. Entries must not have been previously published elsewhere.
Entries will be judged by members of the BSHR Council and should be sent to: This email address is being protected from spambots. You need JavaScript enabled to view it.
Prizes
First prize of £250 (and publication in Invisible Light / BSHR website) Additional prizes may be awarded at the judges’ discretion. Winners will also receive a year’s membership of BSHR.
All entries will be considered for publication in Invisible Light, the Society’s journal, and on the BSHR website. Winners will be announced at the BSHR Online lecture, 8th November 2024.
