摘要:
A method of delivering a radiation therapy treatment plan to a treatment area of a patient. The treatment plan is delivered using a radiation therapy system including a moveable support for supporting a patient, and a gantry moveable relative to the support. The gantry supports a radiation source, a set of jaws having a jaw width and a multi-leaf collimator for modulating the radiation during delivery of the treatment plan. The support is moved during delivery of the treatment plan to the treatment area, and the width of the jaws is dynamically adjusted during delivery of the treatment plan to the treatment area.
摘要:
A system and method of detecting a breathing phase of a patient receiving radiation therapy is disclosed. The method, in one implementation, includes the acts of obtaining a plurality of patient images representing phases of a breathing cycle, delivering radiation to the patient, collecting transmission data of the patient during the delivering radiation, and comparing the transmission data to the plurality of patient images.
摘要:
A system and method of optimizing delivery of a radiation therapy treatment. The system optimizes treatment delivery in real-time to take into account a variety of factors, such as patient anatomical and physiological changes (e.g., respiration and other movement, etc.), and machine configuration changes (e.g., beam output factors, couch error, leaf error, etc.).

摘要:
A system and method of adapting a radiation therapy treatment plan for a patient by varying the fraction size delivered to the patient on any individual day, based at least partially on the use of daily patient registration (i.e., taking images of the patient before each fraction is delivered to see the position and size of the tumor on that day). The fraction size can be dynamically altered based upon the biology of the tumor.

摘要:
A method of calculating a dose distribution for a patient for use in a radiation therapy treatment plan. The method includes acquiring an image of a volume within the patient, defining a radiation source, and defining a reference plane oriented between the radiation source and the patient. The method also includes generating a radiation therapy treatment plan, wherein the plan includes a plurality of rays that extend between the radiation source and the patient volume, and calculating a three-dimensional dose volume for the patient volume from the plurality of rays that intersect the reference plane without first having to independently calculate a dose distribution on each of the plurality of rays. The method can also include displaying the three-dimensional dose volume.
