Method of delivering cell therapy to a target site

A method of delivering therapy to a target site, the method comprising:

• obtaining a base image of the target site;
• navigating a catheter including a delivery needle to the target site;
• injecting through the needle a first dose of a mix of a therapeutic agent and a contrast agent into a first injection location at the target site;
• collecting sequential fluoroscopic images of a contrast agent dispersion cloud at the first injection location;
• determining a contrast agent dispersion region from the sequential fluoroscopic images of the first injection location;
• identifying a tissue type of the first injection location;
• determining a therapeutic agent dispersion region from the contrast agent dispersion region of the first injection location;
• marking the therapeutic agent dispersion region of the first injection location on the base image of the target site;
• injecting through the needle a second dose of a mix of a therapeutic agent and a contrast agent into a second injection location different from the first injection location at the target site;
• and
• determining a therapeutic agent dispersion region for the second injection location and marking the therapeutic agent dispersion region for the second injection location on the base image of the target site, wherein a plurality of the therapeutic agent dispersion regions are presented on the base image at the same time.
