4-D Simulation
A 3D CT image is a snapshot in time. It does not represent the true position, volume, shape or trajectory of a moving tumor. This makes it challenging to define a treated volume that covers the entire range of the tumor’s motion without undue toxicity to the surrounding tissues. Doctor has to visualize the tumor clearly if he/she is to treat it effectively. There is good technology on the treatment end that provides highly conformal radiation beams, but if Doctor does not have accurate localization of the tumor, it doesn’t matter how good the technology is on the back end. 4-D Simulation allows radiation oncologist to assess motion accurately. This information helps decrease the margins around the tumor. The combination of highly conformal radiation beam therapy can accurately deliver radiation dose to the specific position, volume, shape and trajectory of the tumor, which increases the chance of cure and reduces toxicity to surrounding healthy tissue and organs.
