| 内容記述 | Current radiotherapy including photon and particle beams gives prescribed dose preciously, however, intrafractional organ motion is still basic problem in thoracic and abdominal treatment. To solve this, the advantage of 4DCT to quantify organ motion is beyond the conventional 3DCT ability. As a result, local control probability could be improved. The patient will get a significantly inferior treatment with greater complications without 4DCT for tumor localization, albeit that, it is important to clarify the radiation dose from 4DCT. Here we quantified the radiation dose using the anthropomorphic phantom in helical 4DCT scan. TLDs are inserted into the phantom anatomical positions. For thoracic and abdomen scan, the effective doses were 33.1 mSv and 27.5 mSv, respectively. The phantom received a few mSv of the X-ray scattering over the scan region, head and upper lobe of the lung as an example. The exposure dose from 4DCT scan is a little bit higher than that from multi-phase contrast |
