Abstract:
1. A system for calibrating a dose response of an image acquisition device, comprising: one or more treatment planning systems configurable to output a first dose map and at least one subsequent dose map, each dose map indicating dosages that are included in a corresponding treatment plan; one or more image acquisition devices configurable to output a first acquired image and at least one subsequent acquired image, the first acquired image corresponding to the first dose map, each subsequent acquired image corresponding to one of the subsequent dose maps, each acquired image including representations of dosage intensities recorded from an application of the corresponding treatment plan; means for creating a first self-calibration curve that relates the dosages of the first dose map to the dosage intensities of the first acquired image; and means for creating at least one subsequent self-calibration curve that relates the dosages of the at least one subsequent dose map to the dosage intensities of the at least one subsequent acquired image.
