Chinese researchers Dehua Kang, Bin Wang, Yinglin Peng, Xiaowei Liu, and Xiaowu Deng examine methods for improving the bolus, releasing the details of their recent study in ‘ Low-Cost iPhone-Assisted Processing to Obtain Radiotherapy Bolus Using Optical Surface Reconstruction and 3D Printing .’

 .

Boluses generally serve as delivery systems, often for medication. In this study, the research is centered around creating a bolus that ‘acts as a water equivalent,’ assisting in providing dose distribution and good coverage. In creating a bolus via an iPhone and desktop 3D printing system, the researchers worked to create more patient-specific systems—fabricated from two CT images of the patient (one for design of the bolus structure; once for dose calculation after the bolus has been created). Ultimately, a conformal bolus was made with acrylonitrile butadiene styrene (ABS). Procedure of bolus reconstruction using the SFM method. (a) The acquired pictures were imported into SFM workspace […]
