Researchers at Edinburgh University have adapted techniques from astronomy to register complete 3D image volumes to sub-pixel accuracy in real-time. This means that for the first time, full affine correction (to correct for perspective distortions) can be calculated and applied as an imaging sequence is acquired, vastly reducing both bulk subject motion and geometric artefacts from the images.
The core of the technology is a fast algorithm which is able to speed up image processing by factors of 100 to 1,000,000, enabling data from 3D images to be analysed in real time. The technique is applicable to structural magnetic resonance imaging, functional MRI (MRI) and other forms of medical imaging.
The method can be used to assess image quality as the scan progresses, thereby allowing radiographers to stop and re-run the scan if it is not of suitable quality.
The system allows real-time 3D registration, both rigid body and full affine and one click graphical interface operation is possible. It will save time, thus improving throughput and utilization of expensive scanning equipment.
The system runs on commodity computing components and works with DICOM format images direct from an image server, meaning no alterations to the scanner are required
Applications include medical imaging, fast data fitting and analysis; diagnostic aids; quality control; drug discovery and efficacy monitoring; and security
