摘要： Strain is directly estimated in ultrasound elasticity imaging without computing displacement or resorting to spectral analysis. Conventional ultrasound elasticity imaging relies on calculating displacement and strain is computed from a derivative of the displacement. However, for typical parameter values used in ultrasound elasticity imaging, the displacement can be as large as a hundred times or displacement differences. If a tiny error in the calculation of displacement occurs, this could drastically affect the calculation of strain. By directly estimating strain, image quality is enhanced and the reduction in computational effort facilitates commercialization to aid in diagnosing disease or cancerous conditions.

摘要： An in vivo source of compression is used to cause a bodily structure of interest to expand and contract. Ultrasound signals are incident and their echoes are processed by a strain processor. Resulting strain images are freed from noise caused by external sources of compression. A tissue stiffness index is calculated to obtain quantitative measure of stiffness.

摘要： A method and system of strain gain compensation in elasticity imaging is provided. The system can include a probe (120) for transmitting ultrasonic energy into a physiology (150) of a patient (50) and receiving echoes, a display device (170), and a processor (100) operably coupled to the probe and the display device. The processor can process ultrasound imaging data associated with an applied stress of the physiology of the patient. The processor can generate a strain compensation function associated with the applied stress based on at least one of (i) user inputs based on expected results associated with a portion of the physiology, (ii) a strain compensation model generated prior to processing the ultrasound imaging data, and (iii) at least a portion of the imaging data. The processor can apply the strain compensation function to the imaging data to generate a compensated strain image. The processor can present on the display device at least one of the compensated strain image and an inverse of the compensated strain image. Other embodiments are disclosed.

摘要： This invention relates to a method of ultrasonically imaging a region of interest that may contain anechoic and/or hypoechoic echoes.The method comprises the steps of: providing a first and a second set of ultrasound data, said two sets comprising information of the region of interest at two different instants of time respectively, determining from the first and second data sets, a temporal consistency value of at least an area of the region of interest, and producing an image indicating this area as being hypoechoic or anechoic in accordance with said temporal consistency value. Doing so, an anechoic image produced by the method of the invention emphazises the rendering of anechoic and/or hypoechoic areas over echoic ones.
