LAE students in collaboration with Orbyts Fellow Mariana Carreira Bento from UCL Medical Physics & Biomedical Engineering, have made an exciting breakthrough in radiation therapy research. Their project explores the potential of 3D-printed phantoms -customisable, cost-effective models made from common thermoplastics for use in radiation therapy - to replace traditional, commercially available alternatives.

The research focused on six materials: PLA, ABS, HIPS, PETG, PMMA, and StoneFil. By carefully analyzing their linear attenuation coefficients (µ), the students identified remarkable similarities between these materials and various human tissues. ABS and HIPS were found to mimic low-density tissues like breast, adipose, and lung tissue, while StoneFil closely resembled cortical bone. PETG, PLA, and PMMA showed properties similar to brain and muscle tissues.

This innovative discovery has the potential to revolutionise radiation therapy. By providing precise simulations of human tissue, 3D-printed phantoms could improve dose calculation accuracy and treatment planning. Their accessibility and affordability could ensure safer, more effective treatments, ultimately enhancing patient care.

This groundbreaking work highlights the power of student research in driving real-world medical advancements.
