Identifying ARRI ST 'Rontgen' with odd attachment

[Sean Charlesworth]

I have  an ARRI ST labeled 'Rontgen' - I know that usually  means they were for medical/scientific use. It also has an odd side attachment I have never seen. It looks a lot like a sync generator and runs off the camera transmission as well. It has a opening on outer edge that leads into a square hole in the device. It also has a lamp, spinning shutter and what looks to be some type of photoelectric? sensor in the top ring. Curious if anyone can identify this guy.

Any chance of hosting somewhere else? Imgur isn't available in the UK as it won't comply with the online safety law here.

You could just directly post these photos. Which is better anyway, because then they are stored on the forums server and do not suddenly become unavailable.

I only found information about the 35mm versions:

From some Arri brochure (https://www.munichimaging.de/wp-content/uploads/2020/03/Brochure_ARRI_Medical_Surgical-Imaging_German.pdf )
 

In der Medizintechnik war ARRI bereits 1970 tätig. Die analoge Kamera ARRITechno 35 war eine der meistverkauftesten Kameras für den OP. Sie war die erste und einzige Röntgen-Filmkamera, die in Zeitlupe bis zu 160 Bilder pro Sekunde aufnehmen konnte.

Weltweit wurden 13000 Kameras in der Angiokardiografie eingesetzt.

Translation:

ARRI had already been active in the medical technology sector as early as 1970. The ARRITechno 35 analogue camera was one of the best-selling cameras for the operating theatre. It was the first and only X-ray film camera capable of recording in slow motion at up to 160 frames per second.

A total of 13,000 cameras were used in angiocardiography worldwide.

No clue whether the 16mm version also has been integrated into some X-ray unit and whether it was also designed to shoot at 160fps…

The interesting thing is that the well known 35mm Röntgen (X-ray) versions do not have a viewfinder installed. This one has though. I can only imagine that it is a single unit that they built for a customer.

Also, for some reason the buckle witch override button is not installed on the door.

Yeah and typically they would be painted gray. The removal of buckle is odd as well. Otherwise the camera appears to be stock but will know more once I open it up.

One question is: Is 16mm X-ray good enough for medical purposes? Or was this more for industrial purposes, e.g. X-raying goods on an assembly belt for quality checks? (120m of 16mm = more than 1400 single photos)
