  • Cause
    In eclipse the model for linear accelerator treatment head consists of both upper and lower jaws with an optional mlc. in the case of a treatment machine where the mlc replaces the lower moveable jaws (eg. siemens mlc and ge mlc) the lower jaw and mlc is represented in eclipse by combination of virtual jaws and an mlc. the calculation will treat the virtual jaw as a beam limiting device such that the resultant dose distribution will be bounded by the virtual jaw if it lies within the mlc aperture. when calculating or approving a treatment plan if a virtual jaw is positioned inside the mlc aperture a warning will be displayed in external beam planning task when planning for siemens mlc accelerator. this warning states that the virtual collimator jaws are positioned inside the mlc aperture a position which is not physically possible. this warning message is not displayed in case of other accelerator types without back up jaws (eg. ge saturne with ge mlc) or when irreg planning task is being used. if the user proceeds with the calculation the virtual jaws will remain in the current position and will be handled as a beam limiting device for the dose calculation. this will result in the region under the virtual jaw but within the mlc aperture showing no or low dose. treatment using such a plan will result in dose being delivered to the patient outside of the area indicated in the planned dose distribution and within the entire mlc aperture.
