Uniform appropriate levels of stress must be applied for accurate elastograms. If the stress is not applied appropriately, inaccurate results will be obtained, particularly when strain ratios are being estimated. This paper describes a new technique which allows the real\u2010time visualization of the applied stress with a color\u2010coded stress map. The potential use of this map is discussed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ten patients (5 breast, 5 thyroid) and phantoms were scanned using the stress map.
