ASMR

Correlation Model

 Model built at start of treatment fraction  Model is based on 15 data points  Automatic data-point acquisition for evenly distributed points across the breathing cycle

 Various model types

 1 linear type model (no hysteresis)  5 polynomial type models (to account for hysteresis)

 Model updated throughout the treatment fraction  Data points are replaced on a first in first out basis  Automatic image acquisition ensures an even spread across breathing cycle
