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 system and method of evaluating dose delivered by a radiation therapy system using a marker that indicates motion. The marker is associated with the patient. In one method of operation, the method includes delivering radiation to the patient, monitoring motion of the marker during the delivering radiation, and evaluating a dose delivered to the patient based at least in part on the motion of the marker. In another method of operation, the method includes delivering radiation to the patient, obtaining information relating to the delivery of radiation, estimating dose to the marker based at least in part on the information, acquiring dose received by the marker, and comparing the received dose with the estimated dose.
摘要:
A system and method of automatically processing data relating to a radiation therapy treatment plan. The method includes the acts of acquiring image data of a patient, generating a treatment plan for the patient based at least in part on the image data, the treatment plan including a calculated radiation dose to be delivered to the patient, acquiring an on-line image of the patient in substantially a treatment position, delivering at least a portion of the calculated radiation dose to the patient, and automatically recalculating the radiation dose received by the patient.
