Fig. 1. Fungating mass involving the distal phalanx.


Fig. 2. Mock finger contour (gray) and bolus contour (turquoise). 


Fig. 3. Mock electron plan.


Fig. 4. Mock photon treatment plan.


Fig. 5. Patient treatment position.


Fig. 6. Bolus fixed into place using a thermoplastic fixation device with a Styrofoam block.


Fig. 7. 3-D rendering of the photon plan.


Fig. 8. 3-D rendering of the electron field.


Fig. 9. Normalization percentages were chosen to achieve similar coverage of the CTV as demonstrated in the % > Max column.



Fig. 10. (A) Visual evaluation of the transverse, sagittal, and coronal windows demonstrating the photon plan to be more uniform. (B) Visual evaluation of the transverse,sagittal, and coronal windows demonstrating the photon plan to be more uniform.



Fig. 11. The maximum dose point for the photon plan demonstrates 105% at the most distal end of the finger, whereas the electron plan demonstrates a 120% hotspot located at the apex of the bolus. 


Fig. 12. A DVH comparison demonstrating very similar plans.


Fig. 13. NanoDot placement.
