Radiation Treatment Platform and Method Using a Portal Imaging Device to Automatically Control Therapy Administration
A portal imaging device is used to determine an amount of radiation that is delivered to at least one point while administering a radiation treatment therapy to a patient. Upon detecting that the amount of radiation that is delivered to that at least one point exceeds a predetermined amount of radiation (for example, a planned amount of radiation per the radiation treatment plan), administration of radiation treatment therapy to the patient can be automatically halted.
Studying dosimetric impact of motion to generate adaptive patient-specific margins in EBRT planning
A treatment planning system (106) for generating patient-specific treatment margins. The system (106) includes one or more processors (142). The processors (142) are programmed to receive a radiation treatment plan (RTP) for irradiating a target (122) over the course of one or more treatment fractions. The RTP including one or more treatment margins around the target (122) and a planned dose distribution for the target (122). The processors (142) are further programmed to receive motion data for at least one of the treatment fractions of the RTP from one or more target surrogates (124), calculate a motion-compensated dose distribution for the target (122) using the motion data and the planned dose distribution, compare the motion-compensated dose distribution to the planned dose distribution, and adjust the treatment margins based on dosimetric differences between the motion-compensated dose distribution and the planned dose distribution.
Radiation dosage monitoring system
Some embodiments are directed to a radiation dosage monitoring system including a model generation module configured to generate a 3D surface model of a portion of a patient undergoing radiation treatment, an image detector configured to detect Cherenkov radiation and any subsequent secondary and scattered radiation originating due to the initial Cherenkov radiation emitted from the patient, a processing module configured to determine estimations of radiation applied to the patient utilizing the images from the image detector and the 3D model, and to utilize the determined estimations of radiation applied to the patient together with data indicative of the orientation of a radiation beam inducing emission of the Cherenkov radiation at a time when the radiation beam was applied to generate a 3D internal representation of the location of the portions of a irradiated patient resulting in the emission of the Cherenkov radiation.

BEAM-OFF MOTION THRESHOLDS IN RADIATION THERAPY BASED ON BREATH-HOLD LEVEL DETERMINATION
A computer-implemented method of performing a treatment fraction of radiation therapy comprises: determining a current position of a target volume of patient anatomy; based on the current position of the target volume, computing an accumulated dose for non-target tissue proximate the target volume; determining that the accumulated dose is less than a current value for a dose budget of the non-target tissue; and in response to the accumulated dose being less than the current value for the dose budget, applying a treatment beam to the target volume while the target volume is in the current position.
Beam station treatment planning and radiation delivery methods
Described herein are methods for beam station delivery of radiation treatment, where the patient platform is moved to a series of discrete patient platform locations or beam stations that are determined during treatment planning, stopped at each of these locations while the radiation source rotates about the patient delivering radiation to the target regions that intersect the radiation beam path, and then moving to the next location after the prescribed dose of radiation (e.g., in accordance with a calculated fluence map) for that location has been delivered to the patient.
