| titleOfInvention | Determining a radiation treatment plan for delivering radiation to a patient using an external-beam radiation treatment system |
| abstract | A method of determining a radiation treatment plan for delivering radiation to a patient using an external-beam radiation treatment system is described. A first clinical goal and a second clinical goal are received, wherein the first clinical goal includes a first acceptable threshold value and a first desired threshold value for a first quality index relating to a first statistical quantity of a dose distribution, and the second clinical goal includes a second acceptable threshold value and a second desired threshold value for a second quality index relating to a second statistical quantity of the dose distribution. A cost function is obtained which includes a first term with a first weight and a second term with a second weight, wherein the first term is proportional to a value of the first quality index in excess of the first acceptable threshold value, and the second term is proportional to a value of the second quality index in excess of the second acceptable threshold value, and wherein the first weight is inversely proportional to a difference between the first desired threshold value and the first acceptable threshold value, and the second weight is inversely proportional to a difference between the second desired threshold value and the second acceptable threshold value. Optimization then uses the cost function to obtain an optimal radiation treatment plan having an optimal value for the cost function. |
