Abstract
Multiple tumors are grouped into multiple treatment groups. Tumors in different treatment groups are treated by a radiosurgery in different treatment sessions than the tumors in the same treatment groups. The tumors can be grouped so as to decrease the biologically effective dose received by normal tissue in the treatment area. The radiosurgical planning system can divide the tumors into groups based on their location relative to each other and the radiation the tumors will be treated with and create a plan for treating the tumors according to the treatment groups.
Claims18
A method of treating multiple tumors using radiosurgery, the method comprising:
- assigning each of the tumors to one of multiple treatment groups, wherein a quantity of the treatment groups is less than a quantity of the tumors;
- and
- irradiating the tumors using a radiosurgery device in multiple treatment sessions based on the assigning, wherein any two of the tumors that are assigned to different ones of the treatment groups are treated during different ones of the treatment sessions.
A method for radiosurgical treatment, the method comprising:
- assigning each of multiple tumors to one of multiple treatment groups using a computing device, wherein a quantity of the treatment groups is less than a quantity of the tumors;
- generating a treatment schedule including multiple treatment sessions using the computing device, wherein any two of the tumors that are assigned to different ones of the treatment groups are treated in different ones of the treatment sessions;
- and
- treating an area containing at least some of the tumors according to the treatment schedule using a radiosurgical device.
A method for treating tumors in a patient using radiosurgery, the method comprising:
- identifying the tumors in the patient;
- calculating a dose impact for each of the tumors;
- placing a first one of the tumors having a largest dose impact into a first one of multiple treatment groups;
- placing a second one of the tumors having a second largest dose impact into a second one of the treatment groups;
- placing each other tumor into either the first one of the treatment groups, the second one of the treatment groups, or a third one of the treatment groups based on which placement would result in a lowest summed dose impact and a lowest group dose impact;
- calculating a first radiation dose needed to treat each of the treatment groups;
- fractionating the first radiation dose to minimize a second radiation dose to normal tissue in the patient;
- delivering the first radiation dose to each of the treatment groups at different times using a radiosurgical device.
