Innovation for Personalised Cancer Treatment With DEPICT and Wolfmet 3D Tungsten by M&I Materials

Wolfmet 3D printed tungsten collimator is the perfect answer as physics & manufacturing combine to progress molecular radiotherapy imaging.

Wolfmet 3D Collimator - DEPICT Project

Wolfmet 3D printed tungsten collimator manufactured by M&I Materials proves to be the perfect answer as physics and manufacturing combine to progress molecular radiotherapy imaging.

In molecular radiotherapy (MRT) of the thyroid, existing SPECT systems are unable to accurately quantify the radiation absorbed by those patients undergoing treatment. As a consequence, only limited information regarding the success of this radiotherapy treatment has been available — that is, until now.

"The technical solution provided by M&I Materials was ideal for our application. Communication with the team was extremely valuable, and the project benefited greatly from the technical leadership that M&I Materials undertook to produce our design. The final product shows great potential to enable better radiotherapy treatment monitoring."

Experts from the University of Liverpool - Department of Physics, and The Royal Marsden and Royal Liverpool University Hospitals have been working to develop an imaging system (known as DEPICT) that will better quantify the absorbed radiation and help facilitate personalized treatment planning. The ability to individualize treatments is expected to reduce costs by improving efficacy and patient throughput and simultaneously increase rates of successful cancer treatment, leading to improved quality of life and health for those patients.

A critical part of the new imaging system is the CZT detector. This is used in conjunction with a parallel hole collimator with an active area comprising an array of 0.6mm Ø holes. Dismissing the use of lead for such an intricate design because of its unsuitable mechanical properties, the researchers decided that high-density tungsten was the ideal material for the collimator. However, it would have taken many weeks and tens of thousands of pounds to produce the collimator with standard machining methods. The research team realized that they had to find a more innovative solution. That solution was Wolfmet 3D.

Wolfmet 3D is the revolutionary additive manufacturing process provided by M&I Materials (a specialist materials manufacturer based in Manchester, UK). The process utilizes a high-powered laser to fuse successive layers of tungsten powder until a complex component is built. It is perfect for the manufacture of high-precision components such as collimators. Furthermore, collimators can be produced quickly and cost-effectively (in days rather than weeks). The Wolfmet team worked alongside the researchers to establish the optimal design and initial tests have shown the system to be a success.

With its excellent attenuation properties, a Wolfmet 3D tungsten collimator will significantly reduce septal penetration in comparison with the same collimator made from lead — resulting in much-improved image quality.

The team working on the project is hopeful that the DEPICT imaging system will be available commercially in the next 3 years.

We are showcasing Wolfmet 3D products at the EANM Annual Congress 2017 in Vienna, Austria 21st-25th Oct - Hall 2 - 238.
