Summary for lung cancer patients. Positive $D_{\text{pt}}$ means portal image diaphragm is inferior to DRR (more like “inhale” than simulation). $S_{\text{pt}}$ is the SD of D for an individual patient. The estimated error in $D_{\text{pt}}$ is $S_{\text{pt}}/\sqrt{(\# \text{films})}$. Diaphragm excursions are estimated visually from a fluoroscopic movie acquired at simulation. The approximate period and duty cycle are estimated from the CT simulation reference session.
