A system includes determination of a model of a trajectory of a target volume, determination of a treatment plan identifying a portion of the trajectory of the target volume and an irradiation field corresponding to the portion of the trajectory, the portion of the trajectory commencing at a control point of the trajectory, control of a collimator to restrict a treatment beam to the irradiation field, monitoring of the trajectory of the target volume until it is determined that the trajectory is at the control point, and delivery of the treatment beam to the irradiation field in response to determining that the trajectory of the target volume is at the control point. |
