1 Clinical evaluation of interfractional variations for whole breast radiotherapy using 3- dimensional surface imaging  Amish P. Shah, PhD, Tomas Dvorak, MD, Michael S. Curry, MS, Daniel J. Buchholz, MD, Sanford L. Meeks, PhD  Practical Radiation Oncology  Volume 3, Issue 1, Pages (January 2013) DOI: /j.prro Copyright © 2013 American Society for Radiation Oncology Terms and Conditions

2 Figure 1 Examples of AlignRT reference and verification surface images: (A) reference (pink) and verification surface (green) daily registration and (B) the registered region of interest within 2 mm of the reference surface after registration.

3 Figure 2 Schematic showing the sequence of events for patient setup for whole breast radiotherapy when using the AlignRT system. MV, megavoltage; ROI, regions of interest; RT, radiotherapy.

4 Figure 3 Initial target offsets for each fraction: left/right (○), sup/inf (+), ant/post (◊), and 3-dimensional (3D) vector length (■) for (A) 1 patient (No. 7) with moderate AlignRT offsets from skin marks and (B) 1 patient (No. 32) with excessive AlignRT offsets from skin marks.

5 Figure 4 Histograms showing percent of fractions binned by size of initial target offsets for all patients and all fractions: (A) ant/post; (B) sup/inf; (C) left/right; (D) 3-dimensional (3D) vector length.

6 Figure 5 Planned and delivered dose-volume histograms of heart, lung, and volume of prescription isodose line from the treatment plan for (A) patient (No.7) with moderate AlignRT offsets from skin marks; (B) patient (No. 32) with excessive AlignRT offsets from skin marks (data displayed in Fig 3); and (C) left-sided breast cancer patient's treatment (Tx) plan, combined with a separate patient's daily offsets in order to display a possible “worst-case” scenario from daily laser and skin mark alignments with large systematic error.
