摘要： An ultrasonic imaging system is described which visually assists biopsy needle insertion. The system produces pixel values of pixels along one or more paths of needle insertion. A tissue density analyzer is responsive to the pixel values to estimate tissue density along a path of needle insertion. A needle path calculator is responsive to the tissue density analyzer and proposes one or more favorable paths through imaged tissue for insertion of the biopsy needle. The system may be used in conjunction with a three dimensional navigation system which spatially locates the needle and ultrasound image plane in 3D space.

摘要： A system and method for tracking an object (14) received within a body (16) using ultrasound wherein shifts in position of an ultrasound probe (20) tracking the object (either deliberate or accidental) can be corrected for. The method comprises tracking a position of the object through the body using an ultrasound transducer unit, and sensing movement of the ultrasound transducer unit using a physically coupled motion sensor (26). From the movement of the ultrasound transducer unit, movement of its field of view (24) can be determined. Based on a tracked history of positions (28) of the object through the field of view, and on the tracked movement of the field of view relative to the body, a direction of motion of the object through the body can be derived.
