放射治疗CT模拟三维假体校正方法的设计

Development of a Method to Proofread and Correct the 3D Virtual Patient in CT Simulation of Radiotherapy

以有机玻璃板和细铜线为材料,设计了CT模拟三维假体校正工具,测量和校正CT的FOV和层厚,以保证三维重建的3D"假体"与患者实际解剖结构的一致性。

Plexiglass and thin copper wire are used to develop a series of devices, which can proofread and correct the CT ruler and CT interval in scanning so as to guarantee the accuracy for the image of the body in 3D digitally-reconstructed radiography （DRR） in the treatment planning system.
