title: Seven-pinhole multigated tomography and its application to blood-pool imaging: technical parameters.
abstract: The application of seven-pinhole tomography has been predominantly to thallium-201 myocardial imaging. In view of the stationary nature of the collimator, with all views accumulating simultaneously, seven-pinhole tomography can be adapted to dynamic cardiac imaging, namely, multigated blood-pool imaging. Existing reconstruction software was modified to process the gated blood-pool data. The performance parameters of the seven-pinhole system were investigated at Tc-99m energy. This work provides an additional understanding of the seven-pinhole system as well as its potential application to abnormalities of ventricular wall motion or the quantitation of other cardiac parameters from reconstructed data.
