Four dimensional irradiation based on respiratory gating for multiple regions

多种呼吸型式均由JFCR肿瘤研究所医院收集。研制了一种呼吸运动体模，其运动可以模拟患者呼吸波形的呼吸模式。为了在放射肿瘤学中进行高精度的四维治疗，我们开发了一个软件来监测患者在分次治疗过程中身体的连续变化。我们使用运动体模和6名健康志愿者对该软件进行了评估。我们已经证明，该软件足以用于临床使用，并可以通过使用该软件来改进呼吸治疗。

Many respiratory patterns were collected from Cancer Institute Hospital of JFCR. A respiratory motion phantom was developed, whose motion could simulate the respiratory pattern of patient respiratory waveform. In order to conduct high accurate four-dimensional treatment in radiation oncology, we developed a software to monitor consecutive changes of patient's body in intra-fractional treatment. We evaluated the software by using the motion phantom and 6 healthy volunteers. We have shown that the software is sufficient for a clinical-use, and can improve respiratory treatments by using the software.
