ABSTRACT
Purpose:
To evaluate the influence of lung corrections on the target volume dose in radiation treatment of esophageal carcinoma by TPS HEVAPLAN. Materials andMethods:
Three radiation field technique to middle esophagus were used as the model of this investigation .target volume doses were calculated with photons in different energies to compare with the divergence when the lung density were set to 1.0(without lung correction) 0.33 and 0.2 (with lung correction).Results:
If no lung correction was performed, the actual radiation dose in target volume were 24%~28%, 18%~21%, 13%~15% and 7%~9% which were radiated with 60 Co, X-ray of 5MV, 8MV and 19MV.Conclusion:
The lung density must be corrected in treating 60 Co unit.
