Figure 3. Daily set-up magnetic resonance imaging (MRI) for fraction 1 and 25.

Figure 3

Daily set-up imaging using an on-board 0.35-Tesla MRI scanner and a balanced steady state free precession sequence in the sagittal plane for (A) fraction 1 and (B) fraction 25. The bladder (yellow), rectum (purple), gross tumor volume (GTV) (red), and uterus (orange) were contoured on each daily setup MRI. Note the significant reduction in the GTV size, as well as the change in uterine position reflecting inter-fractional motion.
