4D-Radiation Therapy is the optimal treatment to track moving organs(tumor) and give the appropriate prescription dose to tumor and low radiation dose to normal tissue surrounding tumor volume. The ABCHES is a 4DRT devices maintaining shallow breathing to patients. It allows the tumor’s movement was minimize. Meanwhile, Abdominal compression device is limited the breath compressing abdomen on patients. In this paper we will quantitative analysis the movement of tumor on only ABCHES versus ABCHES with Abdomal compression device and Analysis tumor dose and normal tissue’s dose by Dose Volume Histogram on two parts. The result of Comparision ABCHES and ABCHES with Abdominal compression device, SI(Superior-Inferior) direction, AP(Anterior-Posterior) direction and LR(Left-Right) direction was limited 1.0 ㎜, 0.2 ㎜, 0.2 ㎜(average). and also reduction rate of voluume in HPTV was 16 ± 2%, and LPTV was 15.8 ± 0.8% under only using ABCHES and ABCHES with compression. The analysis dose volume histogram was more radiation dose in ABCHES and abdominal compression device than only using ABCHES, and less normal tissue-ipsilateral lung, whole lung, kidney-dose in ABCHES and abdominal compression device than only using ABCHES. The overall analysis was ABCHES with abdominal compression better than only using ABCHES method. In hereafter it will be studies that limitation of ABCHES and abdomonal compression device. In other words, patient’s discomfort on compression intensity, method of application on patient with inaccurate respiration cycle.
