Technical Note: Simulation of 4DCT tumor motion measurement errors

PURPOSE: To determine if and by how much the commercial 4DCT protocols under- and overestimate tumor breathing motion. METHODS: 1D simulations were conducted that modeled a 16-slice CT scanner and tumors moving proportionally to breathing amplitude. External breathing surrogate traces of at least 5-...
