Many years ago my grandfather owned a retail shoe store in Appleton, WI (back before malls). They used an x-ray machine to aid in sizing shoes. As a kid, years after it was put out of service, I came across it in the store basement. The device was about the size of a washing machine, made of a fine cabinet wood, and had a crt on top that allowed customers an x-ray view of their feet with the new shoes on. Fortunately it was no longer working when I found it.
The point is, lack of evidence is no reason to assume a non-invasive procedure is safe. There should be many "hurdles" in place to prevent unsafe medical devices. This is an area where very few consumers can analyze the risk.
- CyberDildonics 11y agoAre you seriously equating electro-magnetic radiation at a frequency high enough to be de-ionizing with the compression of fluids? The difference here is that we know how both of these things work.
- mrfusion 11y agoCombining the two topics... why can't we use ultrasound to size shoes? Anyone want to work on that with me?
- semi-extrinsic 11y agoBecause there are many small air gaps between the shoes and the feet. The impedance mismatch would be huge, and likely throw your signal deep into noise territory. Have you seen the amount of jelly they spread on your skin for medical ultrasounds? I don't think having to submerge your feet in liquid when trying out shoes would win many customers.
- mrfusion 11y agoBut in this case you just need a very rough 2d outline. I believe some stud finders use ultrasound. This might be more similar to that than a medical ultrasound.
- aaron695 11y agoThis is a nice story, but total FUD. Do you actually have evidence of any large amounts of harm this did to people? This attitude is why people don't use vaccines. Fear. It overall hurts the population.
