Wicresoft's guiding die plate and manufacture method thereof.
Background technology
Radiotherapy (radiotherapy) is one of critical treatment method for tumor.For maximum limit
Degree ground reduces radiotherapy side effect and the damage of radiotherapy normal tissue, develops radioactive particle
Implanted treatment technology (hereinafter referred to as seeds implanted).
Seeds implanted is a kind of by inside radioactive source implantation tumour, allows it with the treatment of destroyed tumor
Means.Seeds implanted treatment technology relates to radioactive source, and its core is radion.Seeds implanted
Rely primarily on orientation system by radioactive prospecting instrument tumor body, sent by mini-radioactive resource and hold
Continuous, short-range lonizing radiation, make tumor tissues be killed to greatest extent, and normal structure are not
Damage or only microlesion.
Current seeds implanted operation is typically to be carried out by rule of thumb by doctor clinically, and this is just to doctor
Raw Couple herbs and skill propose the highest requirement.Traditional is carried out under CT is image-guided
Inner irradiation operation, due to exist several so that tens, up to a hundred points of puncture, in art substantially
It is " blind wear ".It addition, the tumor seeds implanted planning system that currently oneself has is all based on one-dimensional
Or bidimensional image data carry out pre-planned to puncturing inserting needle passage, can not calculate the place of particle
Prescription amount, after this just often results in seeds implanted, there is " hot-zone " (dosage mistake in inside tumor
Cause greatly side effect) and/or the adverse consequences of " cold-zone " (dosage is too small to be caused to no effect).
The information being disclosed in this background section is merely intended to deepen the general background to the present invention
