Abstract: A medical diagnostic imaging system and method for adjusting image gain compensation when changing from a first imaging state to a second imaging state, where a first image power value is determined from an image acquired in a first imaging state with a first image gain compensation, a second image power value is determined from an image acquired in a second imaging state with an initial second image gain compensation, an image power change value is determined from the first image power value and the second image power value, and an adjusted second image gain compensation calculated from the initial second image gain compensation and the image power change value.

Abstract: In a medical diagnostic imaging system, a method for adjusting image gain compensation during a transition from a first imaging state to a second imaging state, including the steps of determining a first image power value based an image acquired in a first imaging state with a first image gain compensation; determining a second image power value based on an image acquired in a second imaging state with an initial second image gain compensation; determining an image power change value based on the first image power value and the second image power value; and determining an adjusted second image gain compensation based on the initial second image gain compensation and the image power change value.

Abstract: A method and system are described for displaying an ultrasonic parametric image showing tissue perfusion in registration with an anatomical ultrasonic image of the tissue containing the blood flow. The relative opacities of the parametric image and the anatomical image can be varied, enabling the clinician to view both the perfusion parameters and the blood flow simultaneously or in rapid succession. In an illustrated embodiment the anatomical image or the parametric image can be viewed alone, or in anatomical registration with different or equal opacities. The relative opacity can be changed in a smoothly continuous or stepwise manner.

Abstract: A method and system for tracing a tissue border in a medical diagnostic image are described in which a diagnostic image containing the tissue to be traced is acquired. A user manipulates a cursor on the image display to designate three landmarks on the boundary of the tissue. An automated border detector then fits a stored boundary shape to the three landmarks. The fitted border can thereafter be adjusted to precisely fit the boundary by a rubberbanding process. In an illustrated embodiment the myocardium is traced in an image of the left ventricle by first clicking on the mitral valve corners and the apex, then fitting an endocardial border to these three landmarks, then clicking on the apex of the epicardium, then fitting an epicardial border to the epicardial apex and the mitral valve corners.
