Ionizing-radiation-responsive compositions, methods, and systems
View Patent ↗A method, composition and system respond to ionizing radiation to adjust biological activity. In some approaches the ionizing radiation is X-ray or extreme ultraviolet radiation that produces luminescent responses that induce biologically active responses.
1. A method, comprising:
identifying a first process that at least partially converts ionizing radiation to an amount of optical energy;
identifying a second process that at least partially converts the amount of optical energy to biological activity;
responsive to the identifying a first process and the identifying a second process, determining an amount of ionizing radiation whereby a selected amount of biological activity is produced by a combination of the first process and the second process;
irradiating at least one region with the determined amount of ionizing radiation;
detecting an amount of ionizing radiation that is transmitted or forward scattered through at least a portion of the at least one region; and
determining an amount of biological activity corresponding to the detected amount of ionizing radiation.
2. The method of claim 1 , further comprising:
adjusting the irradiating to obtain the selected amount of biological activity.
3. A system, comprising:
means for identifying a first process that at least partially converts ionizing radiation to an amount of optical energy;
means for identifying a second process that at least partially converts the amount of optical energy to biological activity;
means, responsive to the means for identifying a first process and the means for identifying a second process, for determining an amount of ionizing radiation whereby a selected amount of biological activity is produced by a combination of the first process and the second process;
means for irradiating at least one region with the determined amount of ionizing radiation;
means for detecting an amount of ionizing radiation that is transmitted or forward scattered through at least a portion of the at least one region; and
means for determining an amount of biological activity corresponding to the detected amount of ionizing radiation.
4. The system of claim 3 , further comprising:
means for adjusting the irradiating to obtain the selected amount of biological activity.
5. A system, comprising:
circuitry for identifying a first process that at least partially converts ionizing radiation to an amount of optical energy;
circuitry for identifying a second process that at least partially converts the amount of optical energy to biological activity;
circuitry, responsive to the circuitry for identifying a first process and the circuitry for identifying a second process, for determining an amount of ionizing radiation whereby a selected amount of biological activity is produced by a combination of the first process and the second process;
circuitry for irradiating at least one region with the determined amount of ionizing radiation;
circuitry for detecting an amount of ionizing radiation that is transmitted or forward scattered through at least a portion of the at least one region; and
circuitry for determining an amount of biological activity corresponding to the detected amount of ionizing radiation.
6. The system of claim 5 , further comprising:
circuitry for adjusting the irradiating to obtain the selected amount of biological activity.
