1. A medical imaging system, comprising:
a display screen;
an ultrasound imaging probe, configured to be inserted into a body of a living subject and to generate three-dimensional (3D) ultrasound images of tissue in the body;
a medical probe, which is configured to be inserted into the body and comprises a position tracking device and a transducer configured to contact the tissue, wherein the medical probe is one of a set of at least first and second medical probes, which comprise respective position tracking devices and are configured to be inserted into the body; and
a processor configured to receive the 3D ultrasound images, to receive from the position tracking devices position signals indicating a position of the at least first and second medical probes relative to the 3D ultrasound images, to select within the 3D ultrasound images, responsively to the indicated position, first and second regions of interest containing respective positions of the first and second medical probes, to simultaneously render both the first and second regions of interest to the display screen together with respective representations of the first and second medical probes, to detect a movement of the first medical probe, and to update the first region of interest based at least on the movement of the first medical probe without updating all of the 3D ultrasound images.
