Image-guided delivery of a mixture of bacteria and non-bacteria linked nanoparticles

摘要

A computer-implemented method for image-guided delivery of a nanoparticle mixture to a target tumor located in a region of interest includes selecting a non-hypoxic delivery location within the region of interest for delivery of a non-bacteria-associated nanoparticle component included in the nanoparticle mixture and selecting a hypoxic delivery location within the region of interest for delivery of a bacteria-associated nanoparticle component included in the nanoparticle mixture. An image-guided delivery and monitoring process may then be performed. During this process intra-operative images of the region of interest are continually acquired and used to guide placement of a device into the non-hypoxic delivery location, monitor delivery of the non-bacteria-associated nanoparticle component included in the nanoparticle mixture at the non-hypoxic delivery location, guide placement of the device into the hypoxic delivery location, and monitor delivery of the bacteria-associated nanoparticle component included in the nanoparticle mixture at the hypoxic delivery location.
