Graves' disease with unilateral radioisotope uptake.

Experiences with radioisotope renography in children.

Radioisotope renography provides, from the individual kidney, a graphic record of the renal vascularity, of the excretory funtion of the tubular cells, and of the evacuatory capability of the tubules and the kidney pelvis. By the use of additional scintillation counters, an index of the rate of extraction of the isotope from the blood and its rate of accumulation in the bladder can also be obta...

High-Performance Computing with Accelerators

T his issue of CiSE is based on work presented at the US National Science Foundation workshop, “Path to Petascale: Adapting Geo/Chem/Astro Applications for Accelerators and Accelerator Clusters,” held at the US National Center for Supercomputing Appli cations (NCSA) in early 2009. The workshop was designed to raise awareness about the emergence of accelerator-based high-performance computing (H...

Radioisotope Powered Cardiac Pacemakers.

Over 100,000 implantable cardiac pacemakers are currently being used to rehabilitate patients with heart block. The chemical batteries powering these pacemakers usually fail within a few years. A variety of nuclear batteries with the potential of providing long-lived (10-20 years) pacemaker power, are under development. This paper reviews the status of this development. Nuclear powered pacemake...
