Abstract
An ultrasound imaging system including an image processor configured to receive input data for capturing ultrasound images of a region of interest. The ultrasound images are taken along a first plane; and the input data further includes an indication that a needle will be inserted into the region of interest. The system can capture a plurality of ultrasound images of the region of interest along the first plane. The system can determine one or more high-confidence areas of the region of interest where the needle will intersect the first plane. Each high-confidence area is based on a probability that the needle will intersect the first plane at any portion of the high-confidence area; and display one or more on-screen markers corresponding to the one or more high-confidence areas in conjunction with the plurality of ultrasound images on the display.
