Table 1 Average and standard deviation of photon boost cavity displacements in the three orthogonal directions, and total radial displacement

From: Image guidance using 3D-ultrasound (3D-US) for daily positioning of lumpectomy cavity for boost irradiation

Displacement R/L (cm) S/I (cm) A/P (cm) Radial (cm)
Simulation US reference 0.2 ± 0.8 0.1 ± 0.7 0.2 ± 0.6 1.1 ± 0.5
1st Treatment Fraction US Reference 0.2 ± 0.5 -0.1 ± 0.5 0.1 ± 0.6 0.8 ± 0.4
  1. Results are shown using both the simulation and first treatment fraction scans as the RV.
