Period

This type of x-ray unit probably used c. 1950s- 1960s, and possibly later.

Canada

Used in Ottawa, specifically at 136 Lewis St., by Dr. Powers.

Function

Used to provide graphic images of internal structures.

Technical

Example of an exclusively vertical X-ray machine used in doctors' offices. Variable-pulsed, phototimed fluoroscopy. By using the strobe like effect ofavariable light source, each exposure is optimized. The little photomuttiplier pictured be?low monitors the image for a built-in reference computer. The computer automatically corrects KV in the system to assure uniform in-put to the camera. MTF improves because brilliant light pulses yield more information than the same amount of light from a steady source. And the result is something no other fluoroscopic camera can give you: an absolute maximum in brightness and contrast, with the absolute minimum dosage.
