Intracranial tumor radioactive particle implantation training and dose verification method

Abstract

The invention relates to minimally invasive tumor treatment, in particular to an intracranial tumor radioactive particle implantation training and dose verification method, which comprises the following steps of puncturing a tumor substitute by using a dosimeter implanter, implanting a dosimeter at a specific point, puncturing brain tissue equivalent filler around the tumor substitute, and implanting the dosimeter at multiple points; making a preoperative plan, designing a proper puncture path according to the preoperative plan, determining a puncture layer and a specific position, and using a puncture needle for puncturing the tumor substitutes; implanting particles according to a preoperative plan after all the puncture needles puncture the implantation positions, taking out all the dosimeters and reading actual doses; making a postoperative plan, and comparing the actual dose with the particle dose for verification; according to the technical scheme provided by the invention, the defects that the intracranial tumor puncture environment cannot be truly simulated and the particle dose cannot be effectively verified in the prior art can be overcome.

Description

technical field [0001] The invention relates to minimally invasive treatment of tumors, in particular to a method for training and dose verification of intracranial tumor radioactive particles implantation. Background technique [0002] 125 I radioactive particles are a type of radiotherapy. After the puncture needle punctures the tumor, a micro-radiation source is implanted into the tumor through the needle track, and the particles continuously release gamma rays inside the tumor to kill the tumor. It is mainly used in prostate cancer in foreign countries, but it is used in solid tumors in various parts of the body in my country, and has achieved good curative effect. Since the implantation of radioactive seeds into intracranial tumors requires intracranial operations, the risk is high and the technical requirements are high, so there are relatively few units in the country that carry out this technique. It is difficult for doctors to master this technique through practic...
