    摘要： An ultrasound imaging system (10) is disclosed for creating simultaneous needle and vascular blood flow color Doppler imaging. A B mode image of an anatomical area of interest is created. A first set of Doppler image data optimized for the visualization of vascular blood flow is created along one Doppler image processing path. A second set of Doppler image data optimized for the visualization of a needle or other invasive device is created along another, parallel Doppler image processing path. A color Doppler image is created, and then displayed, by combining some or all of the B mode image, the first Doppler image data and the second Doppler image data based on a plurality of user selectable modes.

    摘要： Significant liver growths such as HCC lesions are detected during a contrast agent ultrasound exam by their early reception of contrast and brightening following a bolus injection, as compared with surrounding normal tissue and benign growths. A pixel classifier looks for and identifies pixel or voxel regions where this early wash-in of contrast occurs and denotes these pixel or voxel locations in a parametric image. The pixel classifier analyzes pixel or voxel values from a sequence of images and identifies suspicious regions in an image by uniquely coding the points in a parametric liver image where early wash-in occurs.

    摘要： Perfusion of tissue such as the myocardium by a microbubble contrast agent is imaged in realtime by a multiple pulse technique which uses low power transmit pulses which are sufficient to elicit a harmonic response from the microbubbles but are not high enough in power to cause substantial destruction to the microbubbles. In a preferred embodiment the realtime microbubble image sequence is displayed in color, overlaid with a grayscale image of the surrounding tissue in the region being imaged.
