Abstract
In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).
Claims20
A radiation therapy system comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to cause the radiation therapy system to,
- obtain a planning image of a target in a human,
- monitor a position of the target,
- compute an occurrence of substantial alignment between the position of the target and the target of the planning image based on a real-time deformation vector-field within a region of interest, and
- trigger a beam of radiation to deliver radiation therapy to the target in less than a second upon the occurrence of substantial alignment.
A radiation therapy system comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to cause the radiation therapy system to,
- obtain a planning image of at least one target volume in a human,
- continuously track a real-time position of the at least one target volume,
- compute an occurrence of substantial alignment between the real-time position of the at least one target volume and the at least one target volume of the planning image based on a real-time deformation vector-field within a region of interest, and
- trigger delivery of a dose of radiation therapy to the at least one target volume in less than a second upon the occurrence of substantial alignment.
A radiation therapy system comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to cause the radiation therapy system to,
- obtain a planning image of at least one target volume in a human,
- continuously track a real-time position of the at least one target volume using four-dimensional (4D) cone beam computer tomography resulting in a real-time video feed,
- compute an occurrence of substantial alignment between the real-time position of the at least one target volume and the at least one target volume of the planning image based on a real-time deformation vector-field within a region of interest, and
- trigger delivery of a dose of radiation therapy to the at least one target volume in less than a second upon the occurrence of substantial alignment.
