The Christie NHS Trust is Europe’s largest cancer treatment and research centre.
Delivering the right dose of radiation into a tumour can dramatically improve treatment outcomes. Standard practice involves the use of simple plastic block “phantoms” to calibrate the radiotherapy device before treating the real patient.
Differing patient physiology limits the accuracy of most phantoms, reducing treatment effectiveness. Physicists at the Christie believed that they could save lives and money with a better solution. An anatomically-accurate phantom, into which sensors could be positioned at the exact location of a tumour, and interchangeable parts replicating bone and tissue density were ideal.
Working with body-scans, we developed interchangeable elements with an indexing sensor positioning system. Our industrial designers used CAD surface modelling to create usable data for on-going engineering.
Materials selection and sourcing suppliers for high tolerance CNC machined components all formed part of a Lucid service in which everything from design to working parts was delivered.
Preliminary trials indicate significant improvements in patient outcomes.
Lucid’s team has subsequently developed several variants to accommodate x-ray sheets and alternative probe sensors.
