Abstract:
Objective To evaluate the clinical application, dosimetry and moving penumbra of traversing beam therapy with moving table technique for total spinal cord irradiation (TSCI). Methods Five patients received 60 Co TSCI traversing beam therapy with moving table which was developed by the Zhejiang Cancer Hospital and Zhejiang University. The maximum moving distance of the table was 60 cm. The dose was measured by ionization chamber. The radiation field size was 5 cm?10 cm and the table moved forward and back. Results Traversing beam therapy was able to increase the percentage depth dose with the dose distribution homogeneous and much better than that of multiple field irradiation. None of these 5 patients developed acute nervous system reactions. Conclusion The 60 Co traversing beam therapy is advantageous in dose distribution, more effective and safer than the traditional irradiation in TSCI .
