He wanted me to mention that we should market a hand-held ultra-sound machine plugged into a laptop for self artery inspection... his clogged arteries were cured through C and he wants more accessible ways to "prove" it. So there, I told you! He said the models he saw were around 30 thousand dollars, but thinks it could be made more cheaply.
After a cursory google search I found this page (hundreds, not thousands of dollars)

Questions.
#1. Could one of these devices be used to monitor progress in blood flow, arterial blockages?
#2. On what possible grounds could a prescription be required for us to obtain and/or see such a device? (Isn't this a free country? he he he)
#3. Why are these hundreds of dollars, when the good Reverend mention multiple thousands?
Added - I do see these are "therapeutic" and not "diagnostic" which might explain the lower cost and prescription...
