Cardiac Insert

Evaluation of cardiac ECT data
Evaluation of attenuation and scatter
Simulates normal and abnormal myocardial uptake
Solid inserts simulate transmural and non-transmural cold abnormalities
Fillable inserts simulate transmural and non-transmural cold or hot abnormalities

This insert provides a multi-function simulation of the left ventricle, and can be used to evaluate SPECT imaging of cold defects within the "myocardium." Two solid acrylic sectors (45 and 60 degrees) are supplied with the insert, each one cm thick and two cm long. These non-filling defects may be placed at various positions within the "ventricle wall", either anteriorly or posteriorly. The long axis of the "ventricle" is adjustable from 30 to 60 degrees from the long axis of the cylinder. Four fillable defects are also included.
