Abstract
Calibrating the dose response of an image acquisition device comprises comparing a first self-calibration curve to a second self-calibration curve to determine the relationship between the curves; modifying an acquired image based on the at least one difference; and applying an initial calibration to the acquired image, whereby the dose response of the image acquisition device is calibrated.

21. A method comprising:
-
creating a first self-calibration curve that relates a first dose map associated with a first radiation treatment plan to a first acquired image recorded from an application of the first radiation treatment plan; and
creating at least one subsequent self-calibration curve that relates at least one subsequent dose map associated with at least one subsequent radiation treatment plan to at least one subsequent acquired image recorded from application of the at least one subsequent radiation treatment plan. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A computer-readable medium tangibly embodying computer-readable instructions configured to instruct one or more processors to perform steps comprising:
-
creating a first self-calibration curve that relates a first dose map associated with a first radiation treatment plan to a first acquired image recorded from an application of the first radiation treatment plan; and
creating at least one subsequent self-calibration curve that relates at least one subsequent dose map associated with at least one subsequent radiation treatment plan to at least one subsequent acquired image recorded from application of the at least one subsequent radiation treatment plan. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
