| 目的 测量和评价介入诊疗区域内常规穿刺平面辐射剂量的分布特点,绘制相应的等剂量曲线示意图。方法 在介入诊疗区域内常规穿刺平面建立测量平台,以X射线发生中心为测量中心,选取常规正位和常规侧位两个基本体位,在八个方向上每0.10m选择一个测量点,每个测量点测量3次,取算术平均值,校正并折算为mGyh。结果 成功测量相关数据并绘制介入诊疗区域内常规穿刺平面正、侧位辐射剂量分布示意图。结论 患者右侧是高辐射场区域,一般为手术人员站立处,辐射强度较高,必须加以防护。患者左上辐射场的强度相对较高,往往安装心脏起搏器时医师容易站在此处,应加以提示。实习医师和进修医师也常在此处观摩手术,应尽量避免。患者左下常为护师给患者输液、加药处,应予以注意。足侧偏左常为电生理技师操作仪器处,虽然辐射强度不大,但也应注意。 |

| Objective To measure and evaluate the distribution feature of radiation dose at the conventional puncture plane in invasive diagnosis and treatment area, and depict the corresponding isodose curve. Methods A platform was built at the conventinal puncture plane in invasive diagnosis and treatment area.By taking the center of X_ray source as the measurement center coosing the conventinal antero_posterior and lateral basic postures and choosing one measurement site for every 0.1 m in 8 directions,measurements were carried out for three times at every measurement point and the arithmetic means,were calculated,corrected and converted to mGy/h. Results We successfully measured doses of X_ray radiation in invasive diagnosis and treatment area,and depicted the distribution curve. Conclusion Generally, the left_superior radiation field of the patient is the strongest,where the physician interns always stands to install a pacemaker.Therefore,the latter should be alerted.The practising physicians and interns often stand there to watch the performance.They should avoid standing there.Nurses always stand in the left_inferior field of the patient doing fluid infusion and adding drugs into the fluid.They should be aware of the danger.Electrophysiology technicians often stand on the left_foot side of the patient,although the radiation dose in not large,they should take care too.Operators always stand on the right side of the patient.They should be protected. |
