This is interesting. Would doctors build/assemble their own machines?
Definitely not the case with newer forms of imaging.
- retrac 1y agoAs the quote says, you only really need two components: an induction coil and a Crookes tube. If connecting the two counts as building their own machine, then yes many early doctors did build their own. An induction coil was an off-the-shelf part (as much as anything electrical was in the 1890s). The Crookes tube was initially a custom piece, but workshops started turning them out as soon as the Roentgen pictures caught on. Maybe worth pointing out that both doctors and laboratory scientists historically had a close relationship with glass blowers and glass work. Many doctors back then would have known someone who was able to make them a Crookes tube (often themselves). A sufficiently hard vacuum pump was I think the trickiest part?
