An ultrasonic diagnosis apparatus includes a position detector, and control circuitry. The position detector detects a position in a three-dimensional space of one of an ultrasonic image and an ultrasonic probe. The control circuitry uses a vivisection view defined in a three-dimensional space. The control circuitry associates a structure related to a subject included in the ultrasonic image with a structure included in the vivisection view using a position and orientation in a first three-dimensional coordinate system of the structure related to the subject included in the ultrasonic image and a position and orientation in a second three-dimensional coordinate system of the structure included in the vivisection view.

An ultrasound imaging system includes a processor programmed to generate an anatomy image and a number of needle frames at different transmit beam angles. The system analyzes the data in the needle frames and selects segments therein that are identified as likely representing an interventional instrument. Data from one or more needle frames are blended with the data for the anatomy image of the tissue to create a composite image of the tissue and the interventional instrument.
