Measurements of the pressure, noise, and radiation dose levels from a Dornier lithotriptor are reported. The distribution of the peak pressure around the treatment focus was investigated, and the highest pressures were found to occur within an elongated volume. Within the treatment room, noise levels of 80-90 dB were produced during each shock wave, rising to 95 dB by the patient's head. Ear protection for the staff and patient is recommended, and careful room design is necessary to minimize the sound disturbance to adjacent quarters. Measurements of the radiation skin dose received by patients from the x-ray localization system were relatively high and ranged from 2-55 cGy (rad), with a mean of 12 cGy. The operator needs to be aware of these high doses and should take precautions to minimize them.
报告了对多尼尔碎石机的压力、噪音和辐射剂量水平的测量结果。研究了治疗焦点周围的峰值压力分布，发现最高压力出现在一个细长的体积内。在治疗室内，每次冲击波产生的噪音水平为80 - 90分贝，在患者头部附近升至95分贝。建议为工作人员和患者提供耳部保护，并且需要精心设计房间以尽量减少对相邻区域的声音干扰。患者从x光定位系统接受的辐射皮肤剂量测量值相对较高，范围为2 - 55厘戈瑞（拉德），平均为12厘戈瑞。操作人员需要意识到这些高剂量，并应采取预防措施将其降至最低。
