  • Verification of mlc leaf position and of radiation and light field congruence
    Patent number: 6760402
    Abstract: A system includes acquisition of first electronic image data representing a phantom located at a first position and irradiated by a first radiation field emitted by a radiation emitter, acquisition of second electronic image data representing the phantom located at a second position based at least on a first light field emitted by a light emitter and irradiated by a second radiation field emitted by the radiation emitter, generation of third electronic image data by correcting the second electronic image data based at least on the first electronic image data, and determination of a deviation between the first light field and the second radiation field based at least on the third electronic image data.

  • Radiation imaging system
    Publication number: 20040022357
    Abstract: A system for capturing an image of transmitted radiation includes transmission of a disable signal to disable a bias light of a camera at a time prior to transmission of radiation, and acquisition of an image from the camera during transmission of the radiation and during deactivation of the bias light. In some embodiments, the disable signal is transmitted in response to the reception of a pre-radiation signal, the pre-radiation signal indicating that transmission of the radiation will commence approximately one frame scan time after the pre-radiation signal is received, and the disable signal is transmitted approximately when the pre-radiation signal is received.
