High Density Dose Map Planning
MapCHECK XY allows automatic expansion of the high density (221 detector) MapCHECK 10cm x 10cm inner field size. Preloaded templates, such as this Head & Neck template, concentrates detectors where they are needed most, and increases the overall field size. By combining multiple measured array positions it is possible to double the detector density. Users may always edit these templates or create their own.

4D Dose Map Planning
Actual “motion envelope” data for X, Y, and Z coordinates is input or imported into the MapCHECK XY/4D software, which is then reproduced by the MapCHECK XY table. The XY table reproduces the XY motion with a MapCHECK on top, and the machine may also be gated via a vertical lift. The end result is irradiation of the MapCHECK array using a simulation of the actual tumor trajectory.
The results can be used to evaluate the efficacy of the gated plan, the 4D duty cycle, and the impact to actual patient structures when breathing patterns are introduced either with or without gating.
