IEEE Rochester Section - Joint EMBS & Life Member Talk
History of CT scanning: From the 50’s to the Present time
Date and Time: March 1, 2017 - Refreshments 6:15 pm, Talk 6:30 -7:30 pm
Location: Goergen Hall, Room 109, University of Rochester, (parking info below)
Parking: Intercampus lot across from Goergen Hall
This talk will start with the beginnings of CT scanning, in the late 50’s and will describe technical advances during the next few decades. This journey will describe various generations of scanners, including cone beam systems with a description of Rochester’s contribution to this field.
The talk will contain a multitude of visuals to illustrate the contributors, technologies, and clinical devices that formed the path to modern medical CT imaging.
CT scanners and techniques have undergone a revolution from the 50’s to the present day. Early scanners scanned one or two slices and had low resolution. The scanning took minutes and the reconstruction times could be measured in hours. Scanners, today, can scan in fractions of a second and reconstruct almost instantaneously and have high resolution.
The advances in CT scanners encompass, Detectors, X-Ray tubes, Gantries, Data Acquisition Electronics as well as reconstruction techniques and rendering. The talk will give a taste of the advances in all of these components of CT scanners. Low dose techniques such as iterative techniques for dose reduction will be described.

Sreeram (RAM) Dhurjaty, PhD
Ram’s first foray into CT scanning was at Yale New Haven hospital, during 78-79where he worked on Image enhancements for the PFIZER 0300FS scanner. He later worked at Analogic Corporation, during the 80’s, designing high speed 16 bit converters for CT scanning and designed Data Acquisition Systems for CT scanning. He later worked at the Health Imaging division of Eastman Kodak designing various imaging devices. He was one of the primary inventors of Kodak’s (now Carestream) Retrofittable digital Radiography system.
Ram has held senior positions at Becton Dickinson medical systems Analogic Corporation, Bose Corporation, and Eastman Kodak and has designed a variety of Medical systems, including fetal monitors and defibrillators. He owns a medical device consulting company in Rochester, and is a co-founder of a Company, in India, that is developing the World’s first hand-cranked defibrillator.
Ram was educated at IIT Bombay and Yale University and has several degrees in Engineering including a Doctorate in Biomedical Engineering. In the 1980’s he was the chair for the Boston chapter of IEEE, EMBS. He was a member of IEEE Committee on Radiation and Man and one of the founders of the IEEE Society for Social implications of Technology.
Ram is a Life Senior Member of the IEEE and is active with the Rochester section of the IEEE.
PARKING & ROOM LOCATION
Upon entering off of Elmwood Avenue, turn onto Wilson Boulevard and go straight through the first stop sign. Up ahead on the left you will be a guard kiosk. Please tell the guard you are here for an IEEE event, and he will hand the participants a piece of paper for the dash of the car and direct them where to park, which is the intercampus drive lot. As you will see on the attached map, intercampus drive lot is across from Goergen Hall. If the participants want to map it, the address is: Robert B. Goergen Hall, Rochester, NY 14627, or see purple highlights below.
Upon entering Goergen Hall, do straight through the doors, and you will see classroom 109 up on your left, on the first floor.
