1. A system comprising:
- a first radiation detector positioned to intercept ionizing radiation directed from a radiation source toward a radiation target before the ionizing radiation has impinged on the radiation target;
a second radiation detector positioned to intercept the ionizing radiation after the ionizing radiation has passed through the radiation target; and
computer hardware configured to receive data generated by the first radiation detector and the second radiation detector and to perform operations comprising;
determining a radiation dose pattern delivered to the radiation target based on the data;
reconstructing a radiation dose imparted to the radiation target based on the data generated by the first radiation detector and the second radiation detector;
comparing the reconstructed radiation dose to one or more limits of dose deposition error; and
generating a user notification when the reconstructed radiation dose exceeds the one or more limits.

Abstract
Data from a first radiation detector and a second radiation detector can be used to determine a radiation dose pattern delivered to a radiation target from a radiation source. The first radiation detector can be positioned to intercept ionizing radiation directed from the radiation source toward the radiation target before the ionizing radiation has impinged on the radiation target and the second radiation detector can be positioned to intercept the ionizing radiation after the ionizing radiation has passed through the radiation target. Methods, systems, articles of manufacture, and computer program products are described.
