Visualizing a trackable entity of interest in an ultrasound image

A method for imaging, comprising:

• receiving ultrasound images of tissue in a body of a living subject from an ultrasound imaging probe within the body;
• receiving position signals from a position tracking device in a trackable entity of interest that is inserted into the body;
• computing, based on the position signals, a position of the trackable entity of interest relative to the ultrasound images;
• selecting within the ultrasound images, responsively to the position, a region of interest that contains the position of the trackable entity of interest;
• rendering the region of interest to a display screen together with a representation of the trackable entity of interest superimposed on the region of interest;
• detecting a change in relative position of the trackable entity of interest and the ultrasound images;
• and
• updating, based at least on the change in the position of the trackable entity of interest, the region of interest without updating all of the ultrasound images.

A medical imaging system, comprising:

• an ultrasound imaging assembly configured to acquire ultrasound image data of a region within a body of a subject;
• a display;
• and
• processing circuitry configured to:
• identify a trackable entity of interest disposed within the body relative to the ultrasound image data;
• cause the display to present a view of the ultrasound image data;
• and
• in response to relative movement of the trackable entity of interest relative to the ultrasound image data, update at least one view parameter of the presented view to maintain the trackable entity of interest within the presented view.

A method comprising:

• identifying a trackable entity of interest disposed within the body relative to the ultrasound image data;
• presenting, on a display, a view of the ultrasound image data;
• and
• in response to relative movement of the trackable entity of interest relative to the ultrasound image data, updating at least one view parameter of the view to maintain the trackable entity of interest within the view.
