Astrocent team members Prof. Masayuki Wada, Dr. Azam Zabihi, and Dr. Iftikhar Ahmad, alongside collaborators from various institutions, have recently published a groundbreaking article on an innovative medical technology poised to revolutionize PET scans. This new approach, called 3Dπ (Three-Dimensional Positron Imaging), introduces a total-body PET scanner that offers incredibly detailed images with lower radiation exposure and faster scan times.
The technology, inspired by the DarkSide collaboration and the emerging advancements in cryogenic photosensors, liquid argon (LAr) detector technology, and low-radioactivity argon procurement, integrates time-of-flight (TOF) technology, ultra-low dose imaging, and ultra-fast readout electronics. The innovative use of a homogenous, monolithic scintillator made from LAr doped with xenon (Xe) significantly improves the system’s performance.
What makes 3Dπ so important?
- Higher quality images
The 3Dπ system achieves an impressive spatial resolution and superior sensitivity.
- Reduced radiation exposure
The use of a novel scintillator offers fast scintillation, enhanced light yield, and reduced radiation for patients, making PET scans safer.
- Faster scans
With ultra-low dose imaging capabilities and shorter scan times, 3Dπ improves patient comfort while providing high-quality imaging.
- Cost-effective
The use of Xe-doped LAr enhances performance while being more affordable, promising a future-proof solution for medical imaging.
By reducing scan times and radiation exposure, 3Dπ holds the potential to transform how we approach medical imaging, making it not only safer and faster but also more effective for patient care.
We are proud to contribute to this exciting development and look forward to seeing how it can improve healthcare practices in the future!
