Collimator for odontological radiology

thingiverse

Objectives: Development an open project rectangular collimator to be attached to intraoral dental X-ray devices, made using recycled lead sheets as a radiation absorbing element. Methods: Initially, the collimator was dimensioned according to the radiographic equipment of the Procion® brand, model Ion 70X-Mobile Column with 70 kV-3mA Class 1 type B common head and in the autoclavable radiographic film positioners of the brand Indusbello and Kerr™ brand number 900170. After defining the dimensions, an STL (Structure Triangular Language) file that could be printed in three dimensions of the positioner was generated and a calculation was performed to define the minimum thickness/layers to offer a reduction in the radiation dose, for the partial definition of the dose reduction it was used as a basis data obtained through Spektr 3.0 software.
