Refillable point source for motion correction during first-pass radionuclide angiography.
First-pass radionuclide angiography, for the evaluation of ventricular function during peak physiological stress, requires the use of a low-energy point source for correction of motion artifacts. A design for the construction of a refillable 125I point source is presented.
