A new imaging technology called omni-tomography could one day be used to combine different medical imaging technologies into one, according to an article in IEEE Spectrum. This could have applications both in research and personalised medicine, says Ge Wang, Director of Rensselaer Polytechnic Institute’s Biomedical Imaging Cluster, the project’s lead researcher. Current combination systems for imaging, such as PET and CT, usually apply the different methods in sequence and not at the same time. There are no systems currently that combine CT and MRI, according to Wang.
Wang developed a technique called interior tomography that is more focused than standard X-ray techniques, thereby reducing patient radiation. Wang’s research demonstrates how the concept can be used in different imaging methods, as well as for the combination of these. Wang and his team have created an engineering design for a CT-MRI scanner that they plan to present in June at the International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine, which will take place in Lake Tahoe, CA, USA. The team does not have the funding to build the combination scanner.
