    摘要: The invention relates to an ablation apparatus for ablating a structure (14) within tissue of a living being. An ultrasound visualization unit (15) generates a two-dimensional or a three-dimensional ultrasound image for finding the structure to be ablated within the tissue. Ablation energy provided by an ablation unit (19) can then accurately be directed to the found structure. Moreover, the ultrasound visualization unit is adapted to generate during the provision of the ablation energy an M-mode ultrasound image by sending and receiving ultrasound waves in the direction, in which the structure is located, as found by using the two-dimensional or three-dimensional ultrasound image, thereby monitoring the ablation procedure. This allows for an improved control of the ablation procedure and, thus, for an improved quality of this procedure.

    摘要: Adjustment of operation of an ultrasound imaging system may be based at least in part on one or more characteristics represented in ultrasound return signals from two or more sample volumes. Adjustment may include adjusting a principal sample volume location or selecting a new principal sample volume. For example, a location of a principal sample volume may be adjusted or new principal sample volume selected so as to remain focused on an identified region of interest or to maintain the principal sample volume relative to some structure or reference. The principal sample volume may be maintained in the center or along a centerline of an artery or other structure, as the transducer array is moved along the artery or structure.
