瑞典和美国一些研究者合作研究应用聚焦超声摧毁癌细胞来治疗脑肿瘤。首先用CT进行脑肿瘤的精确定位。因为超声不能穿透骨,所以必须移除一小块颅骨,头皮仍复盖其上,以利日后愈合。然后,把排除气体的水(因为高频超声不能通过空气)盛于一个锥形容器内,并置于病人去除颅骨的部位。计算机控制的发送器发射超声,高频波从声源以固定距离集中于聚焦点即肿瘤中心。在肿瘤的正确位置造成损伤,摧毁大部分癌细胞。损伤 Several researchers in Sweden and the United States have collaborated on the application of focused ultrasound to destroy cancer cells to treat brain tumors. First of all, using CT for accurate positioning of brain tumors. Because ultrasound can not penetrate the bone, it is necessary to remove a small piece of skull, the scalp is still covered on it, in order to facilitate future healing. The degassed water (because HF can not pass through the air) is then placed in a conical container and placed on the patient’s skull. Computer-controlled transmitters emit ultrasound, which is focused at a fixed distance from the sound source at the focal point, the tumor center. Damage in the correct location of the tumor, destroy most of the cancer cells. damage
