Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.

Abstract: A method for ablation treatment using ultrasound data begins by identifying pathology to be treated and one or more blood vessels proximate the treatment site in a medical diagnostic image. The identified ROI and the blood vessels are automatically indicated in an ultrasound image Ultrasonic Doppler velocity data is acquired from the flow within the vessels and the Doppler data is used to calculate the volume blood flow through the vessels. The thermal effect of the heat transported by this blood flow is considered in the planning or conduct of the ablation treatment, as by modifying the size of a burn zone graphic around the tip of the ablation probe.
