肿瘤放疗CT定位时CT标尺和扫描层间距指示值校正装置的研制

The development of the device to proofread and correct the CT ruler and CT interval in CT simulation for radiotherapy

我们以有机玻璃和细铜线为材料 ,根据一定的数学原理 ,设计研制了一套CT标尺和扫描层间指示值的校正装置 ,从而在肿瘤放射治疗计划和CT定位时CT图像三维重建成为3D“假体”的技术过程中 ,保证了3D“假体”与患者实际解剖结构的一致性 ,在放射治疗CT定位中具有广泛的应用情景。

According to the math principle,we use polystyrene and thin copper wire to develop a device,which can proofread and correct the CT ruler and CT interval in scanning.Thus we can guarntee the accuracy for the image of body in3D digitally reconstructed radiography(DRR)in the treatment planning system.It has bright prospects in CT simula-tion for radiotherapy.
