6. A method of ultrasound needle guidance, the method comprising:
-
acquiring ultrasound data of a first region-of-interest including a needle; displaying a first live image in a first viewing pane, the first live image comprising an overview image defined by the first region-of-interest; tracking a position of a needle tip as the needle is inserted; establishing a second region-of-interest around the needle tip and automatically adjusting a position of the second region-of-interest to track with the needle tip as the needle is inserted; and displaying a second live image defined by the second region-of-interest in a second viewing pane at the same time as the first live image, the second live image including the needle tip at a greater level of zoom than the first live image. - View Dependent Claims (7, 8, 9, 10, 11, 12)

14. A medical system for providing needle guidance, comprising:
-
a needle including a needle tip; a probe, including a plurality of transducer elements; a display device; and a processor, wherein the processor is configured to; control the probe to acquire ultrasound data from a first region-of-interest; track the needle tip while the needle is moved; define a second region-of-interest including the needle tip, the second region-of-interest comprising a subset of the first region-of-interest; adjust a position of the second region-of-interest to track with the needle tip while the needle is moved; display a first live image of the first region-of-interest on the display device based on the ultrasound data; and display a second live image of the second region-of-interest on the display device at the same time as the first live image, the second live image including the needle tip and comprising a greater level of zoom than the first live image. - View Dependent Claims (15, 16, 17, 18, 19, 20)
