Purpose:
Total body irradiation (TBI) in extended source surface distance (SSD) is a common treatment technique before hematopoietic stem cell transplant. The lungs are organs at risk, which often are treated with a lower dose than the whole body.
Methods:
This can be achieved by the application of blocks. Three-dimensional (3D) printers are a modern tool to be used in the production process of these blocks.
Results:
We demonstrate the applicability of a specific printer and printing material, describe the process, and evaluate the accuracy of the product.
Conclusion:
The blocks and apertures were found to be applicable in clinical routine.
