  • Patent number: 11794037
    Abstract: A method for radiation therapy treatment verification includes acquiring: treatment plan information from a radiation therapy system; patient image data; and transit image data received from an electronic portal imaging device during radiation therapy. The treatment plan information is divided into a plurality of segments. Predicted segment image data is determined utilizing a predicted image calculation algorithm and at least the patient image data and the treatment plan information. A predicted integrated image is determined through superposition of the predicted segment image data. Measured segment responses are determined from the transit image data utilizing the predicted segment image data and the predicted integrated image. The measured segment responses are converted to measured segment doses. A measured dose map having a sum of the measured segment doses is compared to a planned dose map based on the treatment plan information to assess radiation treatment delivery.

  • Publication number: 20180185672
    Abstract: A system, a method, and a computer program product for determining a position of a collimator component of a radiation delivery device. Starting and ending times of an image generated by the radiation delivery device are synchronized with a radiation treatment plan executed by the radiation delivery device. The starting and ending times define a period of time when the generated image was acquired. Based on the synchronized starting and ending times, a predicted characteristic of the image is compared to a measured characteristic of the corresponding measured image. The predicted characteristic is determined by the radiation treatment plan. Based on the comparison, a position of the collimator component is determined. The determined position of the collimator component is compared to the radiation treatment plan and/or treatment log. The synchronized starting and ending times of the generated image are then adjusted.
