Abstract
An image-guided system includes an X-ray imaging device for generating one or more X-ray images illustrating a tool within an anatomical region, and an ultrasound imaging device for generating an ultrasound image illustrating the tool within the anatomical region. The image-guided system further includes a tool tracking device for visually tracking the tool within the anatomical region. In operation, the tool tracking device localizes a portion of the tool as located within the ultrasound image responsive to an identification of the portion of the tool as located within the X-ray image(s), and executes an image segmentation of an entirety of the tool as located within the ultrasound image relative to a localization of the portion of the tool as located within the ultrasound image.
