X-Ray Tube

Description:

Cold cathode, four electrode glass x-ray tube with gas auto regulation, designed by Henry Lyman Saÿen and manufactured by Queen & Co. in Philadelphia. It is an example of the first tube that automatically regulated the gas pressure so that the quality and output of x-rays could be maintained.

The donor of this tube was the widow of Chester O. Davison (1888-1967), a graduate of the University of Oklahoma Medical School who headed the radiology department at Vassar Hospital for some 35 years, and then held a similar position at Highland Hospital for six years. Dr. Davison was also a consulting radiologist at the Hudson River State Hospital and the Harlem Valley State Hospital.
