Paper Abstract

We are developing a method for deconvolving overlapped (by 2/3rd) sets of multiple, thick (nominally 8 mm) slices scanned by an Imatron scanner. From these data we generate a 3D image with roughly equivalent resolution in three orthogonal directions. Because this is a tomographic method, the superposition of contrast in the cardiac chambers and pulmonary veins is not a problem and the density resolution is sufficient to permit imaging of arteries opacified with dilute (i.e., 5%) contrast agent, equivalent to that achievable with a intravenous bolus injection of contrast medium. To date we have demonstrated feasibility with postmortem hearts with dilute barium sulfate injected into the coronary arteries. Application in living patients will require modification of the Imatron scanner's table advance and ECG gated scanning software.
