Validation of clinical radionuclide therapy dose distribution by a novel system of 3d printed organs
Lead Research Organisation:
University of Manchester
Department Name: Physics and Astronomy
Abstract
The aim of the project is to show accurate in vivo dosimetry for clinical molecular radiotherapy using single photon emmission computed tomography. This will be done using Monte Carlo simulations and 3D printed patient organs. CT scans of the 3D printed organs, acquired on a hybrid SPECT/CT system, will be used as input for the Monte Carlo simulations allowing the use of voxelised phantom models.

| Title | A custom made elliptical phantom (CATIE, the Christie Anatomical Tomographic Imaging Ellipse) |
| Description | A custom made elliptical phantom (CATIE, the Christie Anatomical Tomographic Imaging Ellipse) has been employed to scan a range of patient organ phantoms to investigate geometrical effects. |
| Type Of Material | Improvements to research infrastructure |
| Year Produced | 2013 |
| Provided To Others? | Yes |
| Impact | The phantom was used at The Christie to allow new data to be collected. These data were analysed and resulted in 3 publications so far. |
| Title | Anthropomorphic Dose Calculation Code |
| Description | A bespoke code was developed to calculate dose for a range of medical isotopes using the DICOM data input. Registration of the regions of interest were used to tag each voxel on the binary image, subsequently used in parallel with the Dose Actor class provided in OpenGATE. This enabled the individual voxelised dose to each organ to be summed respectively, then related to the residency time for the specific radioisotope. Particle filter types were utilised to enable separation of different decay modes impact to dose, namely beta and gamma absorption. |

| PI Contribution | We have provided the physics expertise needed to deliver improved dose calculations for Molecular Radiotherapy treatments at The Christie. This work has combined existing expertise in Monte-Carlo simulation, from basic nuclear physics research, and novel new 3D printing techniques. This collaboration has already delivered improved activity quantification for MRT at The Christie which provide the foundation of accurate and optimised patient dose calculations. |
| Collaborator Contribution | The Christie has provide access to anonymised patient data, clinical SPECT cameras, Molecular Radio Therapy (MRT) isotopes and current MRT dosimetry software which has allowed the techniques developed in this work to be translate to a clinical environment. The research output from this collaboration has provided improved activity quantification and validation of exiting MRT dosimetry software. |
| Impact | This collaboration has delivered improved activity quantification for Molecular Radio Therapy at The Christie which provide the foundation of accurate and optimised patient dose calculations. The research output from this collaboration has provided improved activity quantification and validation of exiting Molecular Radio Therapy dosimetry software. The collaboration has submitted two research papers on this work. |
