dcterms:description
The purpose of this work was to evaluate organ doses and effective doses from three verification techniques in Image-Guided Radiotherapy: from kilovoltage (kV) cone beam CT (CBCT) scans, from two orthogonal kV images, and from two orthogonal megavoltage (MV) images for two different treatment sites: pelvis and head and neck (H&N). For comparison reasons, organ doses and effective doses from prostate and H&N radiotherapy were also evaluated. Measurements of organ doses were performed in a male anthropomorphic Rando phantom by means of thermoluminescent dosemeters (TLDs) MCP-N. In our investigation, measured organ doses from one CBCT scan, from two MV images, and from two kV images of pelvis represent typically 1 to 6 %, 1 to 10 %, and 0.05 to 1 %, respectively, of organ doses resulting from one fraction of prostate radiotherapy. The maximum effective doses from one CBCT scan, two kV images and two MV images of pelvis are 5.6 mSv, 0.8 mSv and 11.9 mSv, respectively.
