Background technique
Malignant tumour, which has become, a kind of seriously threatens human health and common multiple disease.Currently, radiotherapy becomes
One of the three big main means for treating tumour.When radiotherapy mainly penetrates tissue using ray, normal tissue and tumour
Cell controls difference biological respinse mechanism caused by radioactive ray the growth and proliferation for the treatment of tumour cell.With operative treatment
It is compared with chemotherapy, radiotherapy can retain the function of treated organ, and treatment side effect is small, can effectively ensure that patient is cured
Life quality afterwards.
Radioactive prospecting instrument tumour is subjected to internal radiotherapy, also known as brachytherapy is percutaneous or art in lead to
Implant needle or implanting device are crossed by a certain number of radioactive source implantation tumours position, the ray issued using radioactive source is for a long time to swollen
The irradiation of oncocyte, killing or kill tumour cell, to achieve the purpose that treatment.The treatment technology is widely using various
The implanted treatment of entity tumor, achieves good therapeutic effect.It is excellent that this method has that curative effect is high, easy to operate and wound is small etc.
Point.But there is also some disadvantages for this method (radioactivity Implantation in Treating), as influenced after (1) implantation because of organ activity
Source positions and arrangement cause dosage distribution to change, influence therapeutic effect；(2) falling off or migrate there are radioactive source；(3)
Radioactive source stays in the body, and is not easily taken out after treatment, to patient at heart or body brings certain burden；(4) clinical manipulation phase
