I will tell you all that though I found the place 45 minutes away , there was a Dr’s office 7 minutes from my house that had one , but doesn’t use it….. and a large reputable hospital 3o minutes away that has one , but don’t use it !!!! . When I questioned the technician about that she said the dr’s have just decided not to. I was dazed by that response and expressed that to her. Asked her to inquire further and to call me back…. Needless to say that didn’t occur!!!
