Yes, it is Halloween today and my kids could barely contain themselves getting ready for school. I suspect today will not be very productive as they count down the minutes before heading out to terrorize my neighbors.
Anyway, how about this for a scary thought: cinemaradiology! In the late 1800’s John MacIntyre at the Gasgow Royal Infirmary experimented with producing X-ray motion pictures. What!!!? He tried exposing film by passing it between the screen of the fluoroscope and the x-ray tube and by simply filming the fluoroscopic screen. This latter method was very difficult because, as all of you budding radiologists know, the images viewed on the fluoroscope screen were dim and of poor resolution at the time.
For years researchers worked on perfecting cinemaradiology. However, during those early years of discovery they lost interest when they realized that sharper images were possible when BOTH patients and investigators were exposed together AND that excessive radiation was a bad thing – duh!
It would only be many many years later that fluoroscope screen technology would be improved to allow for brighter and higher resolution images (and without frying the patient and everyone around!).
|Fluoroscopy is a study of moving body structures – similar to an x-ray “movie.” A continuous x-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. As an imaging tool, Fluoroscopy is used in many types of examinations and procedures.
To my knowledge, no actors from the cinemaradiology era ever became successful stars in Hollywood…
No need to use the MiWord of the day in a sentence today (see rules here) as I realize you are busy getting ready for Halloween and need a break!

It is hard to believe that the fluoroscope (essentially an x-ray machine used to produce real-time moving images viewed on a screen of the internal structures of a patient) was used to “help” better fit shoes to your feet! From the 1920 to about 1970 you were able to irradiate your feet with x-rays in order to see if you had enough “wiggle-room” in your new shoes! Crazy.
So, the whole concept of Fluroscopy dates back to you know who, Wilhelm Röntgen. We chatted about him here in our blog. He is also responsible for discovering the interesting phenomenon of barium salts fluorescing when exposed to x-rays (see here in our blog).

Soon after Rontgen’s discovery was announced, Thomas Edison (the light bulb guy) decided he could improve on this whole x-ray thing as these rays were produced by a “glass tube apparatus” – something he knew a lot about. After setting his team to work – he had a team as he was a very successful man in those days following his 1879 patent of the light bulb – they soon discovered the risks of working with x-rays. Edison decided to remove himself (literally!) from x-ray research. But before he did he developed one of the first (and arguably the most advanced in it’s time ) fluoroscopes along with a full line of x-ray kits. He also coined the term “Fluoroscope”. Interesting man…
Fluoroscopes have come a long way over the years and are still used today in areas such as orthopedic surgery, gastrointestinal investigations, and angiography but, of course, the dose of x-rays a patient receives is minimized and closely monitored. Have a look at this machine from Siemen’s. “Beam me up Scotty!”.
So how did all of these machines suddenly flood the shoe retail industry? Good question. As it happens, following the development of the high vacuum, hot cathode, tungsten-target x-ray tube by William Coolidge in 1913 the interest for a portable and reliable machine increased dramatically with the advent of the First World War. The successful deployment of numerous machines during the war to aid army physicians spurred the manufacturing industry to mass produce them. After the war, the impact the fluoroscope had on army medicine flowed into community practice.
Due to the enormous supply of portable x-ray machines at the time following the end of the war, Dr Jacob Lowe introduced the idea of using a modified portable x-ray machine in the shoe retail industry. Voila, fried feet fricassee for the next 50 years!
Now If were to be interested in using a fluoroscope to look at my feet I may be inclined to use a suit like this gentleman below is sporting…

Now for the fun part, using Fluoroscope in a sentence by the end of the day:
Serious: Bob, did you know that the foot-o-scope was a modified fluoroscope used to view ones feet when fitting new shoes which delivered on average 13 Roentgens for every 20 second exposure?
Less serious: I heard grampa grumbling he can never find shoes that fit right anymore since they banned fluoroscopes in shoe stores. What is a fluoroscope mommy?
Listen to High Heels to decompress and I’ll see you in the blogosphere.
