Technology Research Of The Digitalisation Plumbous Model In Actinotheraphy

In the field of treating cancer, actinotheraphy has become one of the mostimportant measures of local treatment. Using plumbous model is one of the measureswhich are fit for outline to prevent patients from the harmful radicalization. Nowsome hospitals typecast the model with plastic mould. However, it has somedisadvantages, such as low precision, plumbous and plastic pollutions.The integrated channel, machining the plumbous model with the mechanicalmeasure, is put forward and established in the thesis. At first, the parameters ofplumbum are acquired from the experimentation of milling and line-cut to ensure thatthe plumbum can be milled. Then the design of the software system is accomplished.If every parameter is correct after importing the electro-picture, X or CT radiograph,the software will finish the RGB transform and boundary filtrate to assure the figureposition through reading the value of every point of the image. Then the systemacquires the array of the figure coordinate via the method of "seeking for pointsfollow the outline". It draws the integrated outline and three-dimensional former withthe B-spline. You can check whether it is right or not by coordinates counterchangingfrom each point of view. If it is not in accordance with user's demand, the image orthe parameters can be modified. Then the numerical-control programming text will becreated and transmitted to the machine.The results of the work are valuable for improving the actinotheraphy precisionand reducing the pollution.
