Leeds medical imaging seminar Wednesday February 10th in Room 8.49N Worsley Building, Leeds at 4pm. Professor Terry Jones, Visiting Professor at the University of California Davis, will present his talk on: "Improving the Sensitivity of Positron Emission Tomography" Abstract: Positron emission tomography (PET) is the most specific and sensitive means for imaging molecular pathways and interactions in humans. However, the axial field of view (FOV), and hence the axial length of the body, which current PET scanners can image at one time is less than ~25cm. This limited FOV means that less than 1% of photons emitted by the radiotracer in a human subject are actually detected. To realise the full sensitivity of PET for imaging humans a 200cms long scanner is required. To this end, a recently funded USA National Institutes of Health program to build the world’s first total-body PET scanner will be described together with the expected step changes this technology will bring in the applications of PET in clinical research and health care. http://medhealth.leeds.ac.uk/events/event/445/ Contact Harry Tsoumpas

Jakob Sauer Jørgensen Limited-data X-ray tomography and sparsity regularization at RAL (Harwell Campus) Abstract: In this seminar I will give an overview of some recent results and ongoing projects within limited-data X-ray tomographic reconstruction and sparsity regularization. First, I will describe a special limited angle tomography problem in which metal bar sample holders cause cone-shaped parts missing in the sinogram. I will describe our attempts of characterizing and preliminary results of removing the resulting artifacts. Next, I will present a projection matching algorithm for automatically aligning tomographic projections of unknown exact orientation. In the present case we are interested in ultra-high resolution tomographic reconstruction from ptychography data. Currently, unknown sample translations and rotations at the nano-scale for example caused by vibration limit the achievable reconstruction quality. I will show preliminary results with simulated and real synchrotron ptychography data. Finally, I will mention our attempts of establishing a connection between image sparsity and the amount of undersampling admitted by sparsity-regularized reconstrution methods. In particular, I will describe simulation results suggesting how one may predict the sufficient number of projections to acquire based on the sparsity level of the scanned object. I will then point to a potential follow-up study for validation on real data using the SophiaBeads? data set recently released from the University of Manchester
