System for determining a position of an interventional device in an ultrasound image based on a position of the interventional device in an x-ray image

A method comprising:

• receiving an x-ray image of a region of interest of a subject including an interventional device provided in the region of interest of the subject during an interventional procedure;
• determining a rough position of the interventional device in the x-ray image;
• acquiring ultrasound data of the region of interest of the subject including the interventional device provided in the region of interest of the subject;
• determining a refined position of the interventional device in the ultrasound data based on the rough position of the interventional device in the x-ray image;
• and
• displaying an ultrasound image of the region of interest of the subject and the interventional device based on determining the refined position of the interventional device in the ultrasound data.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• receive an x-ray image of a region of interest of a subject including an interventional device provided in the region of interest of the subject during an interventional procedure;
• determine a rough position of the interventional device in the x-ray image;
• receive ultrasound data of the region of interest of the subject including the interventional device provided in the region of interest of the subject;
• determine a refined position of the interventional device in the ultrasound data based on the rough position of the interventional device in the x-ray image;
• and
• display an ultrasound image of the region of interest of the subject and the interventional device based on determining the refined position of the interventional device in the ultrasound data.
