Here is one of my "near misses" on an Internet search for information about detecting vulnerable plaque using external, non-invasive ultrasound. The artcle referenced below use miniturized ultrasound hardware that is inserted into major arteries. This article also provides a lot of information about vulnerable plaque, which is main reasion I am posting about it here.

One of drivers for my search for information about detection of vulnerable plaque is a heart attack that happened to a friend of mine. It was result of a vulnerable plaque that ruptured, leading to formation of clot that blocked one of his cornary arteries, leading to heart attack. He survived. When they enplaced a stint at the location where the clot blocked the artery, they found quite plaque-free artery and never did develop any information about location of the vulnerable plaque that ruputred. He had no "risk factors" for heart attack, including quite acceptably low total cholesterol, LDL, etc.
Did he simply get "struck by lightening, or, can vulnerable plaques that are good candidates for rupture be located and treated? IF SO, sounds like a more rational approach than feeding hundreds of millions of folks poisions like statins to combat a fake problem.
Scanning several additional articles about detection of vulnerable plaques leads to conclusion that what progress is ongoing is using intravascular methods NOT non-invasive as I have been interested in. Kind of a bummer!! I will continue this search till I get a definitive answer. However, I am begining to suspect that I will not be spending my health insurance money on Carotid-Intima-Media-Thickness data, just to get a low-resolution "age" of my carotid arteries.
