短距离放射治疗(Brachytherapy),包括腔内放疗、表面模型和组织内插植放疗,是放射治疗学中与远距离放射治疗(Teletherapy)相呼应的一大分枝。它的特点是能够有效地控制肿瘤的局部病灶。自1898年居里夫人发现镭以来,以此作为放射源的短距离放疗在癌的治疗中发挥了很大的作用。到40年代,镭序已成为一种治疗方法,为放疗科等肿瘤临床工作者所用。但是,许多长期从事镭疗的医护人员 Brachytherapy, including endoluminal radiotherapy, surface models, and tissue implants and radiotherapy, is a major branch of radiation therapy that echoes teletherapy. It is characterized by the ability to effectively control the local lesions of the tumor. Since Madame Curie discovered radium in 1898, short-range radiotherapy as a radioactive source played a significant role in the treatment of cancer. By the 1940s, laser radiography had become a treatment method used by radiology clinicians and other cancer clinicians. However, many medical workers who have long been engaged in radium therapy
