Clinical PET/CT scanners deliver non-invasive, precise anatomical and functional imaging of the human body. Did you know the same systems have been used to investigate plants?
A team of cross-disciplinary researchers at the University of Melbourne, University of Adelaide, and the University of British Columbia have teamed up to demonstrate the utility of clinical PET/CT scanners to image plants.Read More
Frontline medical workers put themselves at risk during a pandemic to deliver critical health care and save lives. Personal protective equipment (PPE) such as gloves, gowns, and face shields can reduce the risk of infection. To prevent contamination through airborne droplets, healthcare workers can employ an air-purifying respirator to push filtered air into their face shield or hood.Read More
The NIF Molecular Imaging & Radiochemistry (MIR) Theme is a group of NIF Fellows, Directors, and users of NIF facilities that focus on state-of-the-art radiochemistry and molecular imaging applications using PET, SPECT, and MRI.
Integrating preclinical PET systems into a national resource requires the development of defined QA programs to monitor and integrate the data from individual systems. Hence, the MIR Theme initiated a national quality assurance (QA) program for the NIF preclinical PET instruments.Read More
The Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS) exists to enable national-scale research facilities, thereby facilitating Australian researchers to address critical national and global challenges effectively and efficiently. NCRIS projects provide equipment, resources, analysis tools and, importantly, expertise.Read More

3D printing is increasingly being used in the healthcare industry to customise medical devices to meet patient-specific needs. Currently, device manufacture is lengthy, limiting the application of customised medical devices. The treatment of traumatic injuries requires intervention as quickly as possible, preferably within days post-injury.
This collaborative research project between the Dept. of Biomedical Engineering at the University of Melbourne and the Dept. of Orthopaedics at the Royal Melbourne Hospital aims to assess the feasibility of 3D printing fracture plates to treat traumatic fractures and speed up the production of devices at the point-of-care for a patient. By performing a proof-of-concept experiment on a set of cadaveric pelvis, Dr Dale Robinson and team are evaluating each phase of the 3D printing workflow. Once implanted, a series of computational models and biomechanical experiments will be used to assess whether the 3D printed fracture plate offers an improvement over a traditionally mass-manufactured plate. Paramount to designing customised implants, the anatomy of each pelvis is being characterised using the University of Melbourne’s NIF Node CT with input from PET/CT Facility Fellow Rob Williams and radiographer Rebecca Glarin. After implantation of the fracture plate, CT may assess the effectiveness of the device in terms of stabilising and reducing the fracture.
To date, the project has conducted some scans and used this data for preliminary printing of implants. Plates were designed and printed in collaboration of researchers at Johnson and Johnson and the University of Melbourne. The initial study used 3D printed medical-grade titanium and 3D rendering from the NIF facility CT. In developing this method, iterative reconstruction with maximal overlap to printing was used to be consistent with typical medical CT. This was done while still using radiation dosimetry within standard limits.
This project has the potential to improve patient outcomes by enhancing surgical intervention durability, reducing the duration and number of surgeries, and reducing the risk of life-threatening surgical complications (such as pulmonary embolism and infection) through reduced bedtime. Consequently, the effective implementation of customised 3D printed medical devices is expected to reduce healthcare costs through shorter hospital stays and reduced number of surgical interventions.
