Biomolecular contrast agents with multiple signal variance for therapy planning and control in radiation therapy with proton or ion beams

摘要

A bio-molecular contrast agent (BMCA) is introduced into a biological organism such that the agent binds or reacts with target tissue within that organism. The BMCA is also signal-giving, allowing control of particle beam therapy by tracking the signal given by BMCA. The BMCA gives multiple signals which interact with different tissue elements in different ways. The variance in these signals is utilized to determine the constituency of the tissue either before and/or during therapy.
