1. A method of planning radiation treatment for a patient, the method comprising:
identifying a region of interest of said patient to be treated with radiation;
determining a simulated treatment plan for said region of interest based on a statistical analysis between one or more metrics of said identified region of interest and a previously determined predictive dynamics database that includes information regarding said one or more metrics for corresponding regions of interest for a population of patients; and
characterizing said simulated treatment plan with a FLASH Index that compares an ideal FLASH radiation treatment plan to said simulated treatment plan, wherein
the FLASH index includes a FLASH Plan Index encompassing all organs at risk, and
the FLASH Plan Index includes an average of a plurality of FLASH Indexes, each of the FLASH Indexes corresponding to a single organ at risk.
 
9. A method of planning radiation treatment for a patient, the method comprising:
accessing a simulated radiation treatment plan for the patient;
determining a FLASH Index for the simulated radiation treatment plan; and
displaying the FLASH Index on a graphical user interface on a radiation treatment planning computer system, wherein
the FLASH index includes a FLASH Plan Index encompassing all organs at risk, and
the FLASH Plan Index includes an average of a plurality of FLASH Indexes, each of the FLASH Indexes corresponding to a single organ at risk.
