Abstract

Background: This study describes the possibility of implemen ng threedimensional prin ng technology to create a precise construc on of a planned bolus, based on computed tomography informa on stored in the Digital Imaging and Communica ons in Medicine (DICOM) format file. Materials and Methods: To create the bolus with a 3D printer, we converted data in the DICOM format to the stereolithography (STL) format. In addi on, we produced a paraffin bolus that, tradi onally, is manually placed directly on the pa ent. CT scans were acquired for both boluses, and the images were superimposed onto the pa ent CT scans that were used to design the bolus. The superimposi on of images was performed to compare the fit of the bolus printed on a 3D printer to that of the paraffin bolus made in the tradi onal way. In addi on, for both models, the dose distribu on was simulated. To quan fy the level of matching ML, special formula was used. The ML parameter had a value between 0 and 100%, where 100% indicated a perfect fit between the model and the 3D printed bolus. Results: We verified that 100% of the volume of the 3D printed bolus was located within the contour of the designed model. The ML of the bolus was 94%. For the classical paraffin bolus the ML was only 28%. Conclusion: A bolus printed on a threedimensional printer can faithfully reproduce the structure specified in the project plan. Compared to the classical paraffin bolus, the three-dimensional printed bolus more closely matched the planned model and possessed greater material uniformity.
