Modified tablet PC guides interventional MRI scans
By Erik L. Ridley
The MRI suite wouldn't seem to be the safest place to use a tablet PC, but an interventional MR physicist has found a way to make it work. Using an HP TouchPad modified to work within powerful magnetic fields, Andrew Holbrook, PhD, hopes to make it easier to perform interventional MR scans.

Heavy-metal contrast cuts radiation dose
By Eric Barnes
Wednesday, November 30 | 3:10 p.m.-3:20 p.m. | SSM20-02 | Room S404ABCompared with some heavy metals, iodine and barium simply don't produce enough contrast in CT to optimize dose, according to medical physicist Tristan Nowak, from the Institute of Medical Physics at Friedrich-Alexander-University Erlangen-Nuremberg. In a study to be presented Wednesday afternoon, his group tested several heavy metals in phantoms in the search for an eventual replacement.
