Fuzzy logic guided inverse treatment planning
A fuzzy inference system for use in modulating radiation treatment includes a fuzzifer for inputting imaging data, and inference device operatively to the fuzzifer for analyzing the imaging data and determining radiation treatment target from non-treatment target, and a defuzzifier for modulating radiation treatment pursuant to the analysis from the inference device.
1. A fuzzy inference system for use in modulating radiation treatment, said system comprising:
single input fuzzifier means for inputting and optimizing singular imaging data and a physician's treatment intention including dose/volume constraints for critical organs, normal tissues, targets and compromising strategy between critical organs, normal tissues, and targets;
inference means operatively connected to said fuzzifier means, said inference means for analyzing the imaging data and the physician's treatment intention and determining radiation treatment target from non-treatment target; and
defuzzifier means for modulating radiation treatment pursuant to the analysis from said inference means.
2. The system according to claim 1 , wherein said system is computer based.
3. A method of modulating radiation treatment by:
inputting patient data into the fuzzy inference system according to claim 1 ;
and modulating radiation treatment pursuant to data obtained from the fuzzy inference system.
4. The method according to claim 3 , wherein said modulating step includes automatically modulating radiation treatment.
5. The method according to claim 4 , wherein said modulating step includes automatically modulating radiation treatment via a computer.
6. The method according to claim 3 , wherein said modulating step includes increasing the amount of radiation at a specified location.
7. The method according to claim 3 , wherein said modulating step includes decreasing the amount of radiation at a specified location.
8. An apparatus for producing modulating radiation therapy in patients, said apparatus comprising:
an imaging device for creating and storing image data of relevant tissue and organ parts; and
a fuzzy inference system according to claim 1 , said system operatively connected to said imaging device for modulating radiation treatment.
9. The apparatus according to claim 8 , wherein said system is computer based.
10. A fuzzy inference system for use in modulating radiation treatment, said system comprising:
single input fuzzifier means for inputting and optimizing singular imaging data and a physician's treatment intention including dose/volume constraints for critical organs, normal tissues, targets and compromising strategy between critical organs, normal tissues, and targets;
inference means operatively connected to said fuzzifier means, said inference means for analyzing the imaging data and the physician's treatment intention and determining strength of radiation treatment; and
defuzzifier means for modulating radiation treatment pursuant to the analysis from said inference means.
11. The system according to claim 10 , wherein said system is computer based.
